Electro On-Field DPS

Example Build: Reliquary of Truth, 4-piece Thundering Fury, ATK% | Electro% | CRIT, 120% ER

Lisa’s core identity, and best use case, is to be an On-field Aggravate DPS due to having integral components favoring both the reaction and the playstyle. By being within an Aggravate team, she gets substantial use out of her EM Ascension stat, innate and frequent Electro Application, Constellations, access to DEF Shred, and being on-field as a Driver in general. Compared to other characters who can fulfill a similar role as an On-field Aggravate DPS, Lisa stands out by preferring 20–25s rotations; wanting a secondary Electro in the team; having multiple sources of Electro Application when on-field; having far-reaching ranged attacks and an off-field presence; and simultaneously buffing teammates through her A4 Passive. “Quickburn” is another powerful composition composed of a generic Aggravate team with a Pyro unit included. All benefits from her Aggravate teams apply similarly, and, as such, “Quickburn” will be considered a subset of the Aggravate archetype.

Otherwise, Lisa can still be played as an Electro On-field DPS in other compositions such as “Quickbloom,” Lunar-Charged, Electro-Charged, or Overloaded. However, her effectiveness in these setups is not as optimal as it is within an Aggravate team due to less synergy. Nevertheless, depending on the characters available, these archetypes can still be viable.
When placed in a Lunar-Charged, Electro-Charged, or Chevreuse Overloaded team, Lisa should focus on building ATK%/Electro%/CRIT rather than towards EM. In these configurations, the added Elemental Reactions contribute supplementary damage rather than serving as the main focus.

Being a Catalyst user with a relatively quick execution on her Normal Attacks, Lisa may also act as a Driver for other off-field damage dealers. These can range from Beidou, Xingqiu, Yelan, or others that utilize attacking with Normal Attacks. When playing with such characters, attempt to rotate Lisa’s Hold Skills between cooldown downtime.

Electro Off-Field DPS

Example Build: Hakushin Ring, 4-piece Emblem of Severed Fate, ER% | Electro% | CRIT, 180% ER

Lisa’s arguably more intended and officially recognized role is as an Off-field DPS. Here, Lisa focuses on having her Elemental Burst as her primary source of damage off-field and buffing the team via her A4 Passive. Relative to other off-field Electro characters, Lisa's contribution can be the most potent in AoE scenarios or when buffing a character has priority. When built as such, she often will only execute her Elemental Skills and Elemental Burst, with her Normal Attack talent being less utilized. 

Lisa prefers to be off-field in teams where Dendro is available, as her significance heightens from taking advantage of the Quicken reaction tree. She can still be effective elsewhere without Dendro when off-field, but her damage contribution shines less prominently.

Lisa often requires a longer rotation time of around 20 seconds as she does not have short CDs.
Be sure to acknowledge her Cooldowns and Rotations since these are key.

This archetype also gradually betters as Lisa gains Constellations, unlike some other playstyles. Regardless, she works perfectly fine off-field without Constellations since they are more QoL than anything (except C4).

Reaction DPS

Example Build: Fruit of Fulfillment, 4-piece Flower of Paradise Lost, EM | EM | EM, 220% ER

As a Reaction DPS, Lisa builds entirely differently from her other usual builds, opting to maximize her reaction damage by purely stacking EM and ER%, though this same reason is also why Lisa is looked down upon as a Reaction DPS—at least, in the general public. Realistically, this archetype sees proper use in two variations: Hyperbloom and Overloaded teams. In contrast to the Electro-Charged reaction, Electro-Charged is not viable to build towards as a Reaction DPS for Lisa as who will have ownership is inconsistent and near unmanageable. As for the Lunar-Charged reaction, Lisa would rather have a generic Electro DPS build. In comparison to other Reaction-forward characters, namely Hyperbloom triggers, Lisa is distinct by having her primary trigger be her Elemental Burst and contained to an area; being one of the highest potential offensive options because of her Elemental Burst's optimal 0.5s tick rate and access to a teamwide buff from her A4 Passive; but requires high ER% investment and does not consolidate healing.

Lisa can either be played on-field for more Electro Application, usually with accompanying sources of high Hydro/Dendro or high Pyro Application, or off-field, with Lisa’s Elemental Burst being the main trigger with even more sources of high Pyro or Hydro/Dendro. In either case, both rely on her Burst’s uptime; hence, ER% becomes increasingly valuable.

Despite its ease of access from only requiring two stats, properly investing in this archetype can be troublesome as there is not much to invest towards after building the main team structure and needing to balance ER% by sacrificing EM. Lisa’s only real impactful Constellation to herself as a Reaction DPS is solely her C4, majorly providing more consistency in triggering the respective reactions between intervals.

Support/Buffer/Enabler

Example Build: Thrilling Tales of Dragon Slayers, 4-piece Noblesse Oblige, ER% | … | … , As much ER as needed

As a Support/Buffer/Enabler, Lisa aims to assist the team through her valuable DEF Shred passive on her Elemental Burst and provide plentiful utility from her weapon options as a Catalyst user. She will often only utilize her Elemental Burst, with her Hold Elemental Skill used out of necessity or omitted entirely.

Due to not requiring much investment for Lisa to be effective as a Support/Buffer/Enabler, she can be a fairly common choice. While this role does not encompass Lisa as a character, it can be just as viable due to how effective her supportive capabilities remain with simply her passive and weapon utility.

Common areas where this archetype shines are when buffing an on-field character is preferred or when a team requires a low-investment—yet effective—teammate. Otherwise, with a bit of extra investment, these builds are usually better off being modified to become an Off-field DPS that also emphasizes supporting but to a lesser degree. However, there are scenarios where it is best to place Lisa as a completely supportive option rather than an Off-field DPS.

Artifacts

Artifact Stats

While this section remains to distribute accurate information, should it be necessary, using the Genshin Optimizer to construct proper artifact sets can be noticeably accommodating for Lisa—and for future characters in general.
Within the Genshin Optimizer are a bountiful amount of guides to help players get started. For Lisa in specific, do check out these multi-target optimization configurations as well as highlight 4-piece Thundering Fury!

Low Investment

At lower investment levels, assembling Lisa as some form of DPS is still generally optimal. That said, choosing to build her as a cheap Support remains just as feasible, as this archetype primarily relies on her 15% DEF Shred and weapon utility, neither of which requires significant investment.

When comparing Electro utility options at minimal investment levels, Lisa can be proportionally better because her benefits are unique, constant, and not reliant on her damage.

Higher Investment

With increasing investment, Lisa unquestionably shines more as an On-field Aggravate DPS, with Off-field and Reaction archetypes also viable because of how her reactions scale and her still relevant efficacy. Meanwhile, the Support Lisa archetype at higher investment levels begins to morph into an Off-field DPS or a Reaction DPS if to maximize her potential output, only that it is a hybridization of focusing on her Burst and pure utility instead of dedicating herself to deal damage.

Energy Recharge Requirements

Electro Resonance On-field (1 Hold Skill)	100% – 130%
Solo Electro On-field (1 Hold Skill)	130% – 160%
Solo Electro Off-field (1 Hold Skill)	170% – 200%
Electro Resonance Off-field (1 Hold Skill)	130% – 160%
Electro Resonance Off-field (No Hold Skill)	180% – 210%
Reaction DPS (1 Hold Skill)	200% – 220%
Cheap Support	As much as possible for Elemental Burst uptime.

Please understand that these ER requirements assume various criteria. Many of these values will fluctuate and likely overestimate with play as enemy count, player ability, and HP particles are not taken fully into account.
C1 and funneling are other factors as well.

Use them as a guideline, not strict requirements.

Main Stat Ideals

	(Electro) On-field DPS	(Electro) Off-field DPS	Reaction DPS
Sands	ATK% ≥ EM*	ER%** / ATK% ≥ EM*	EM / ER%**
Goblet	Electro%	Electro%	EM
Circlet	CRIT Rate / DMG	CRIT Rate / DMG	EM

*An EM Sands can be comparable damage-wise to an ATK% Sands if and only if Lisa is played in a Quicken-related team. In which case, an ATK% Sands is better in pure Aggravate but an EM Sands is better in Quickburn/Quickbloom. Otherwise and outside of such teams, an EM Sands holds little value.

**As either an Off-field DPS or a Reaction DPS, an ER% Sands should be used if Lisa cannot regenerate her Burst on given rotations. However, situations do exist where Lisa, as an Off-field DPS/Reaction DPS, can supply herself with an ATK%/EM Sands, respectively, and rely on ER% substats instead.

Offensive Substat Priorities

On-field Aggravate DPS	1. CRIT 2. ER% 3. EM if ATK% Sands; ATK% if EM Sands 4. ATK% if ATK% Sands; EM if EM Sands
General On-field DPS	1. CRIT 2. ER% 3. ATK% 4. EM
Off-field DPS	1. ER% until sufficient 2. CRIT 3. ATK% (and/or EM if in a Quicken team)
Reaction DPS	1. ER% until sufficient 2. EM 3. ATK% or CRIT

Electro Lisa Sets

Electro Lisa Artifact Overview

4-piece Thundering Fury	As an On-field Aggravate DPS, 4TF is unequivocally Lisa’s Best-in-Slot (BiS) artifact set. 4TF’s Electro DMG%, Bonus Reaction% damage, and Cooldown Reduction (CDR) are all massively beneficial for Lisa. Its Electro% and Reaction% are valuably effective in her Aggravate teams, with added benefit if other reactions like Hyperbloom or Overloaded are present, and the CDR brings her extensive utility — including when plunging.  At first, the benefits of having CDR for Lisa may not be apparent since allowing more Hold Skills is not inherently positive. Attempting to force more Hold Skills only extends field time and becomes unwieldy to manage. However, why its CDR proves to be worthwhile is how it can shorten Lisa’s setup time, enables her to use her Hold Skill anytime in a rotation, and allows chaining her Tap Skills for enhanced attack strings, thus maximizing Aggravate triggers and slightly improving her Energy Generation. Do note that, outside of On-field Aggravate teams, 4TF is only marginally valuable compared to other available sets.
4-piece Gilded Dreams	4GD is a selective set but can do well for Lisa if she is along with Dendro.  Often, 4GD will give Lisa 14% ATK and 100 (+80) EM in such teams, which is relatively valuable for raw stats. Otherwise, outside of On-field Aggravate teams, the value of its EM rapidly decreases and becomes of little value. 4GD would be more effective than 4TF in an Aggravate team if Lisa is positioned more off-field.
4-piece Marechaussee Hunter	4MH is a highly restrictive set, intended only for use when Lisa is alongside Furina in any of Lisa’s Electro-Charged or Lunar-Charged teams. However, it fares strongly in such scenarios, often a BiS. 4MH competes effectively due to the dearth of great artifact options in these respective archetypes, making the set's already powerful CRIT Rate buff enunciated. Otherwise, 4MH should never be used on Lisa if Furina is not a teammate, as receiving HP fluctuation will be inconsistent, and its 2-piece effect is negligible.
4-piece Long Night’s Oath	4LNO can be a viable set when Lisa is enabled to plunge by Xianyun. Realistically, it is an option in Lisa's Aggravate, Electro-Charged, and Lunar-Charged Plunge teams, but not ideal. Naturally, Lisa can consistently maintain 3–5 artifact stacks while on-field because of her Tap Skill's short cooldown. Even so, however, 4LNO is not optimal. In Electro-Charged and Lunar-Charged Plunge teams, where Furina is a likely teammate, 4MH rises over instead. In Aggravate Plunge teams, the QoL and flexibility of 4TF make it stand out compared to 4LNO, even though their performance is somewhat comparable. In situations where 4MH or 4TF are less significant, 4LNO may be more advantageous.
4-piece Night of the Sky’s Unveiling	4NotSU can be offensively optimal for Lisa when the following conditions are true: Lisa is intended to be on-field, Lisa is in her Quickbloom or Lunar-Charged teams, and there are multiple Nod-Krai teammates present (Moonsign Level 2+). The assortment of teams available is limited, thus 4NotSU is a very niche set. Should all prerequisites be valid for Lisa, 4NotSU provides sizeable CRIT Rate, valuable EM, and a teamwide buff to Lunar Reactions.
4-piece Thundersoother	4TS performs relatively well in a fair amount of Lisa’s teams.  Since Lisa has the potential to manage her Electro aura with proper rotations and ability usage, it is easy to meet 4TS’ precondition. If micro-management is not an issue, 4TS can be ideal for the above teams, excluding various Dendro teams as many other Elemental auras can be present for an Electro aura to be consistent.
4-piece Emblem of Severed Fate	4EoSF is another selective set for Lisa, yet is ideal for her in any Off-field DPS role. Given Lisa requires substantial ER from being off-field, 4EoSF gets considerable value. However, outside of this archetype, 4EoSF is noticeably weakened as she often will not require high ER benchmarks due to her on-field teams having frequent sources of Energy.
2-piece Combinations	Depending on Lisa’s selected archetype, her viable 2-piece sets include: • 2-piece Thundering Fury • 2-piece Noblesse Oblige • 2-piece 20% ER • 2-piece 18% ATK • 2-piece 80 EM Split sets remain a decently well-rounded option in most areas because of their ease of attainability.  Of them all, 2-piece Thundering Fury has the highest priority due to Lisa appreciating its versatile DMG% more and being a step closer to building a proper 4TF set.

2-piece and 4-piece Golden Troupe (GT) should not be used on Lisa if you aim to build her effectively—it is completely anti-synergistic with how relevant other artifact sets are. Lisa cannot also connect her Hold Skill under 4GT’s maximum buff due to swap delay, even with perfect execution. GT’s only use to Lisa is to flex or showcase large numbers on her Hold Skill.

Reaction Lisa Sets

Hyperbloom or Overloaded

Reaction Lisa Artifact Overview

4-piece Flower of Paradise Lost	4FoPL is the best set for Hyperbloom Lisa in terms of damage, namely due to its raw and strong increase in Hyperbloom DMG%. The only potential downside for 4FoPL is that its domain is typically less effective to farm than the domain for Gilded Dreams and Deepwood Memories.
4-piece Gilded Dreams	With Lisa as a Reaction DPS, 4GD generally gives the most value to this archetype when dealing with Overloaded reactions. In her Hyperbloom teams instead, 4FoPL outperforms slightly. Due to these teams often consisting of non-Electro units, 4GD will amount to Lisa a staggering 230 EM.
2-piece Combinations	If the above sets are not attainable by some means, then any split between various 2-piece ER% and EM sets is viable due to the raw value 80 EM or 20% ER brings to this archetype.
4-piece Thundering Fury	4TF is only near the other artifact sets above because its extra 40% Reaction DMG manages to be less effective than the pure EM/ER% other sets give at reachable EM levels due to being a constant additive bonus rather than a multiplicative one.  4TF only becomes strictly better than the above sets if Lisa is running a near-impossible amount of EM on her gear, which is highly unlikely.

Support/Buffer/Enabler Sets

4-piece Scroll of the Hero of Cinder City	Although Lisa cannot access the full buffing potential 4Scroll has, allowing her to buff teammates with a 12% DMG Bonus buff can be highly worthwhile, especially when Lisa generally has less artifact options as a Buffer. Typically, 4Scroll is best in teams where Lisa is buffing non-ATK-scaling characters—like when alongside a Quicken on-fielder. 2Scroll’s Flat Energy generation can be selectively useful in niche cases for Lisa, provided a teammate originates from Natlan.
4-piece Noblesse Oblige	Otherwise, for ATK-scaling teammates, 4NO’s 20% ATK buff can be a potentially more optimal choice on Lisa than other artifact sets. 4NO also welcomely buffs Lisa’s Burst damage and she is able to equip it without egregious drawbacks.
4-piece Silken Moon’s Serenade	Although rarely equipped on Lisa as a proper buffing set, 4SMS still can be a viable option. It has the potential to provide a teamwide 60 or 120 EM buff, depending on the team’s Moonsign Level. 4SMS also further buffs Lunar Reactions, although this itself is anti-synergistic to Lisa’s kit and DEF Shred, While there are not many teams that can effectively utilize Lisa with the 4SMS set, it is still worth noting that the 2-piece effect grants a 20% ER bonus.
4-piece Instructor	While generally not advised for Lisa to equip due to reasons such as low uptime on its passive, mandating Lisa to swap in more often, and naturally having fewer stats as a 4-star artifact set, 4Inst’s teamwide 120 EM buff can be a niche, cheap option as a Buffer in select Quicken teams.

Electro Lisa Weapons

Electro Lisa Weapon Overview

As a brief guideline for her weapons in Dendro-inclusive teams, weapons that boost ATK% become weaker in comparison.

The order in which each weapon appears is loosely ranked.

Reliquary of Truth	Reliquary of Truth is Lisa’s definitive BiS weapon for personal damage across a majority of her teams. Although Lisa cannot utilize the enhanced passives of Reliquary of Truth, which requires her to deal Lunar-Bloom damage, its impressive and unconditional CRIT DMG, CRIT Rate, and EM still make it her optimal choice. The EM buff is most effective with 4-piece Thundering Fury for permanent uptime, but it still provides effective uptime even under other circumstances. Reliquary of Truth’s stats make it exceptionally powerful for Lisa in her ideal Dendro-inclusive teams compared to other weapons.
Kagura’s Verity	Kagura’s Verity is a strong, competitive weapon for Lisa’s personal damage. It also has the best numbers for showcasing Lisa’s Hold Skill, should it ever be needed. For Lisa, building up weapon stacks is feasible with her Tap Skills since she only needs to execute 2 Tap Skills for a future maximally-buffed Hold Skill. As an On-field DPS, there is ample time to build up the weapon's passive. Otherwise, if she is in a role that cannot mandate that setup time, causing her to mistime the buff or not gain it entirely, it becomes comparable to the other 5-star weapons.
Lost Prayers to the Sacred Winds	Lost Prayers manages to be a competitive option from its raw stats in some of her archetypes, but especially within Aggravate as the CRIT Rate becomes greatly enunciated. Many of Lisa’s preferred teams only allow her to garner up to 1 to 2 weapon stacks naturally, lessening the weapon’s max potential. However, its added Movement Speed compliments Lisa’s lack of mobility, especially when she stays on-field.
Vivid Notions	In any of Lisa’s Plunging teams, Vivid Notions instantly becomes her BiS weapon since she can readily activate the secondary passive with her Tap Skill, also bolstering 4-piece Thundering Fury’s effectiveness.  Aside from Plunging teams, Vivid Notions’ raw constant ATK% and CRIT DMG allows it to be a consistent and competitive weapon among other archetypes, regardless. For example, when Lisa is an Off-field DPS, Vivid Notions is often ideal for personal damage despite ignoring most of its passives.
A Thousand Floating Dreams	Within Lisa’s Dendro-related teams, Thousand Floating Dreams sees notable worth as a weapon, often juxtaposed with or directly under other 5-star weapons.  In such teams, Thousand Floating Dreams buffs Lisa once in EM and twice in DMG% from commonly having another Electro unit and other units like a Dendro and a Flex slot. Its teamwide EM buff is another benefit as well. For purposes like where sources of Hydro or Pyro may be present, allowing occasional Hyperblooms or Overloadeds, Thousand Floating Dreams also does comparably better due to its raw EM. Outside of Lisa’s Dendro-related teams, Thousand Floating Dreams quickly drops in value since its EM substat becomes barely potent.
Tome of the Eternal Flow / Surf’s Up / Nocturne’s Curtain Call	Although these 5-star weapons’ passives are nearly nonexistent for Lisa, they can still be a viable option in her Aggravate teams due to their sheer CRIT value.
The Widsith	Comparatively, Widsith often will be Lisa’s BiS 4-star weapon; it can be similar to 5-star weapons as well.  Within Aggravate teams, Widsith’s CRIT DMG and all of its possible passives remain effective and useful. Thus, it unequivocally is Lisa’s best 4-star in that scenario. Otherwise, outside of Aggravate, getting the EM buff is virtually ineffective and rotation times will have to be taken into account for proper usage.
Cashflow Supervision	Cashflow Supervision is a niche BiS for Lisa, only becoming her best weapon when paired with Furina in her Electro-Charged teams. In Lunar-Charged teams instead, although Furina is still commonly chosen, other weapons fare more prominently. In such teams, Lisa prefers driving with Normal Attacks more than in her Aggravate teams and has easy HP fluctuation from Furina, making Cashflow Supervision’s ATK SPD and buffs powerful.
Skyward Atlas	Skyward Atlas is a solid weapon for Lisa’s non-Aggravate archetypes. Innately, Skyward Atlas carries both DMG% as well as ATK% and high Base ATK from its raw stats. Since Lisa does not naturally gain any sources of DMG%, it remains an effective static passive even when under external attack buffs. That said, because of its ATK% substat, attack buffs aren’t as impactful relative to other weapons.  However, in Aggravate teams, the ATK% does not garner as much value as it would otherwise and becomes undervalued.
Dawning Frost	An adequately performing 4-star option in most of Lisa’s teams. Dawning Frost is her best 4-star within Quickburn and Quickbloom, where both CRIT and high EM are recommended.
Solar Pearl	Solar Pearl is a well-rounded weapon for a 4-star.  Its dual DMG% passive meshes well with Lisa’s kit overall in any given scenario. Due to this, any external attack buff also complements this weapon to the point where high refines can compete against low-refined 5-star weapons. One thing to note is that both parts of its passive are not able to be snapshotted.
Blackcliff Agate	If being able to stack its passive proves to be tangible, Blackcliff Agate can rival well against other options.  However, realistically speaking, stacking it will be more difficult than not and will most likely be a CRIT DMG stat stick in the end. It is more recommended to spend your Starglitter elsewhere than for Blackcliff Agate.
Flowing Purity	Flowing Purity is Lisa’s best craftable 4-star weapon for personal damage if healing is accessible, providing an ample DMG% buff. Should healing be omitted, Flowing Purity falls behind other craftable weapons.
Mappa Mare	Mappa Mare is a viable weapon for Lisa, providing EM and a fair DMG% buff.  Mappa Mare is strictly inferior to Flowing Purity if activating Flowing Purity’s passive is possible. If other reactions like Overloaded or Hyperbloom are present or healing is absent, then Mappa Mare can outperform Flowing Purity.
Hakushin Ring	Hakushin Ring is often Lisa’s best craftable 4-star weapon as an Off-field DPS.  Overall, Hakushin Ring provides valuable stats to Lisa: ER% and teamwide DMG%. However, it only shines if Lisa is in the position as an Off-field DPS where the ER% is appreciated. Otherwise, if she is an On-field DPS with a sufficient Battery, Hakushin Ring should not be considered an offensive option.
Sacrificial Jade	Although Sacrificial Jade carries a valuable CRIT Rate substat and an EM buff, its other HP% buff is completely wasted on Lisa. As a Battle Pass weapon, Solar Pearl outclasses Sacrificial Jade entirely.
Favonius Codex	Although Favonius Codex may lack offensive output, its passive Energy Generation can be very useful. Often Favonius Codex can be considered as an option if Lisa is more primarily focused on getting her Burst or others’ Bursts up in time. Otherwise, do not use Favonius Codex if your aim is damage.
Fruit of Fulfillment	For the purpose of building towards Electro damage, Fruit of Fulfillment should not be considered. It can give high amounts of EM and does have an ER% substat, but the diminished ATK% often will be why it does not compare well. Fruit of Fulfillment does see great use in another archetype, however.
Sacrificial Fragments	Sacrificial Fragments is only listed here to highlight its flaws, as this weapon should not be used on Lisa when built toward Electro in any way.  The EM substat is marginally effective, even within Aggravate. Its CD reset also does not get tangible use on Lisa because it can potentially trigger through her Tap Skills and would only elongate rotations if used for her Hold Skills.

Reaction Lisa Weapons

Hyperbloom or Overloaded

Hover to expand the image

Reaction DPS Weapon Overview

For a Reaction build, weapons that yield an EM or ER% substat are of high value because these are effectively the only ways to boost Lisa’s output. For the most part, these builds disregard her usual role as a source of regular Electro damage.

Etherlight Spindlelute	In this archetype, Etherlight Spindlelute has all the components necessary to be ideal for Lisa as a Reaction DPS, having 45.9 ER% and up to 200 EM from its passive. Its sheer stat volume makes it consistent enough to outperform even 5-star EM Catalysts. Etherlight Spindlelute, however, is an event-exclusive weapon.
Fruit of Fulfillment	Should Etherlight Spindlelute not be available, Fruit of Fulfillment is a craftable weapon that provides almost similar stats in volume.  It topples other weapon choices by providing 45.9 ER% from substats and up to 180 effective EM from its passive. Its ATK% debuff is also barely detrimental due to most of the damage of this archetype residing in reactions. All other craftable options pale to Fruit of Fulfillment in this archetype for personal damage.
Starcaller’s Watch	Starcaller’s Watch has a staggering unconditional 365 EM (at R1), the most out of any Catalyst.  The massive raw EM alone allows Starcaller’s Watch to have the maximum total rotational damage in Lisa’s Reaction teams. However, Lisa will never activate the weapon’s buffing effect and will need to focus on meeting her Energy needs.
5-star EM Catalysts	Stemming from being 5-star EM weapons themselves, these weapons provide at least 265 EM constantly and are offensively strong, at the cost to meet ER requirements: A Thousand Floating Dreams, Sunny Morning Sleep-In, and Nightweaver’s Looking Glass.
Favonius Codex	Favonius Codex can be of great value in part of its Energy Generation, which Lisa, as a Reaction DPS, would crave. Having Lisa’s Burst up consistently can be more important than dealing more Reaction damage, in which case, Favonius Codex stands strong.  Many of the teammates in her Reaction teams also wield high Energy Cost Bursts in tandem with Lisa, allowing Favonius Codex to potentially side as a Battery for teammates as well. If necessary and with high refinements, Lisa can opt to stay on-field to trigger its passive more often provided she has some amount of CRIT Rate.
Sacrificial Fragments	Due to Sacrificial Fragments having a high constant EM substat value at 221 EM, it can see fair use in this playstyle provided the ER requirements are met too. Sadly, however, even in this archetype its passive remains practically useless.
Magic Guide	Although Magic Guide is a 3-star weapon, it has a relatively high constant EM substat value at 187. As EM is mostly the only thing that matters for these kinds of builds, it is a solid option for players who do not have the above weapons. Be cautious as leveling it to 90 purely for its EM may be a waste of resources.
Wandering Evenstar	Wandering Evenstar, unlike its usage for Electro Lisa, can be of some use in her Reaction builds.  Having an EM substat, Wandering Evenstar is already a potential option in that regard but can get marginally more value due to its passive’s Flat ATK bonus having a larger effect when Lisa is built toward her Reactions.
Hakushin Ring	Hakushin Ring is outperformed by Fruit of Fulfillment in terms of personal damage, but can still have value. Of all the ER% providing weapons that aren’t Favonius Codex, Hakushin Ring also allows additional buffs to the Pyro/Hydro characters in the team, which can potentially be more effective than increasing Lisa’s personal damage. Do note that the passive requires Lisa to trigger it when she is on-field.
The Widsith	Technically, Widsith can also provide EM, but this is legitimately a last resort option as, often, you would be sacrificing a majority of her stats to fulfill a Reaction build. It does have the highest potential EM though, albeit purely random.

Support/Buffer/Enabler Weapons

The weapons listed here are not ranked in any order, as each carries varied benefits.

Hakushin Ring	Hakushin Ring is a great choice for this archetype; specifically if only the other Elemental DMG% buff proves to be useful, often which being with Dendro. Do note that the passive requires Lisa to trigger it when she is on-field, which may need to be accounted for.
Thrilling Tales of Dragon Slayers	At R5, TTDS provides a hefty ATK% boost to whomever Lisa swaps onto.  TTDS is familiar as a supportive weapon as the increase in ATK% is often substantially appreciated and is commonly owned. The only real downsides to TTDS are that not all rotations will have its cooldown on the ready and that its effectiveness lessens notably in Quicken teams, allowing Hakushin Ring to be better.
Favonius Codex	Favonius Codex can pair very well with this archetype.  In the cases that Lisa is necessary for her Burst uptime for her DEF Shred or for supplying the team with additional Energy, Favonius Codex is assuredly a safe and usable option.
Prototype Amber	Prototype Amber's passive notably enables Lisa to heal allies, giving her a niche in Furina teams as an efficacious support. Also, it alleviates her Energy Generation slightly by providing Flat Energy to herself.
