Off-field DPS Fischl AKA Oz requires little field time, switching in only to cast her Skill (summon Oz) and her Burst (refresh Oz’s duration). This playstyle enables Fischl to be a battery and Electro reaction enabler.
While playing Fischl as an on-field DPS is generally a suboptimal playstyle, it is a personal preference players can opt for.
Fischl as an on-field DPS utilizes both Physical and Electro damage from various parts of her kit. This playstyle has many variations due to players being able to choose whether they want to emphasize her Electro or her Physical damage.
Off-Field DPS: Skill > Burst
On-Field DPS: Skill = Normal Attack > Burst
Fischl’s Talent priority is dependent on her playstyle and build.
For off-field DPS builds, it is not recommended to level her Normal Attack.
As a general rule of thumb for on-field DPS builds: If you are using an Electro Goblet, prioritize her Skill. If you are using a Physical Goblet, prioritize her Normal Attack.
Normal Attack | Bolts of Downfall
A 5-hit string that can deal respectable Physical damage for on-field DPS builds. It allows Fischl to work as a driver for units such as Xingqiu and Beidou or a trigger for weapon passives such as Prototype Crescent.
Elemental Skill | Nightrider
Fischl’s Skill summons Oz who stays on-field to deal single-target Electro damage for 10s (or 12s with C6) with a 25s cooldown (effectively a 15s downtime). Oz’s initial summon will snapshot any buffs, and his resummon will re-snapshot. Despite Oz’s awkward rotations, he is the premier Electro battery and a consistent Electro reaction enabler. His damage should not be neglected, even for on-field Physical DPS builds.
Elemental Burst | Midnight Phantasmagoria
Fischl’s Burst allows her to take the form of Oz and fly across the field with increased movement speed for 2s, dealing Electro DMG to nearby opponents. At the end of the transformation, Oz is summoned at her location. If Oz is already on the field, he will be resummoned and his duration will be refreshed. After the Burst transformation ends, Oz’s attacks are still considered Skill DMG. As such, the damage from Fischl’s Burst is not as important as its ability to refresh Oz’s duration for essentially 100% uptime.
Since Fischl cannot dash or attack during her transformation, it is recommended to cancel Fischl’s Burst early by swapping to another character as soon as possible.
Ascension 1 Passive | Stellar Predator
Fischl’s A1 Passive deals AoE Electro DMG if Fischl hits Oz with a fully charged shot. While the damage from this passive is sizable, it is not worth using even for on-field DPS builds.
Ascension 4 Passive | Undone Be Thy Sinful Hex
Fischl’s A4 Passive deals Electro DMG to the closest enemy if an Electro-related reaction is triggered by the on-field character while Oz is also on-field. This passive is an integral part of Fischl’s kit due to its lack of ICD and low cooldown (0.5s), allowing Fischl to be a very consistent Electro applicator.
Constellation 1 | Gaze of the Deep
When Oz is not on the field and Fischl fires a Normal Attack at an enemy, Oz (in the form of a purple orb) will fire a coordinated shot that deals Physical damage. Damage dealt in this way is considered Normal Attack damage.
Fischl’s C1 is only relevant to on-field Physical DPS builds, but even then, it is not optimal since high Oz uptime is preferred for both more damage and energy generation. C1-oriented playstyles are purely player preference.
Constellation 2 | Devourer of All Sins
The AoE Electro damage when summoning Oz is increased by 200%. This is a 200% additive increase to her talent multipliers and only affects Oz’s initial summon. A small overall damage increase.
Constellation 3 | Wings of Nightmare
Increases the Talent Level of Fischl’s Skill by 3. Fischl’s second-best Constellation due to Oz making up a significant portion of her damage for both off-field and on-field DPS builds. Slightly less valuable for on-field DPS builds centered on Fischl’s Physical damage and C1.
Constellation 4 | Her Pilgrimage of Bleak
At the initial cast of her Burst, Fischl’s C4 provides an additional instance of Burst damage in a small AoE. Additionally, Fischl will heal herself when her transformation ends. The damage increase through C4 is minimal, but the healing is a nice survivability boost.
Constellation 5 | Against the Fleeing Light
Increases the Talent Level of Fischl’s Burst by 3. This does not increase her C4 damage, but does increase the damage dealt when Fischl comes in contact with an enemy during her Burst transformation. Another overall minimal damage increase.
Constellation 6 | Evernight Raven
Fischl’s best Constellation. C6 extends Oz’s uptime by 2s and causes Oz to perform coordinated Electro attacks (instead of auto-targeting) when the on-field character uses a Normal Attack. This effectively increases Fischl’s Electro application and is a sizable damage increase.
Combos (On-field DPS only)
N# = Corresponding number of consecutive Normal Attacks
AS = Aimed Shot (not fully-charged)
|N2 AS||Fischl’s highest personal damage string and the best at triggering Beidou’s Stormbreaker.|
|N5 AS||An easy and perfectly acceptable combo; worse than N2AS at triggering Beidou’s Strombreaker, but better at triggering Xingqiu’s Rain Swords.|
Off-field DPS Fischl’s ER requirements are highly variable and can depend on whether you have her C6 (which can reduce ER requirements by ~10%), what team she is in, and the enemies you are facing. For a more accurate estimate, use Zakharov’s Energy Recharge calculator.
|~120-140%||Off-field DPS, burst every rotation|
|~100%||Off-field DPS, burst every other rotation|
|~110-130%||On-field DPS (with Oz)|
Ideally, Oz’s uptime should be maximized to increase Fischl’s personal damage. However, Fischl’s awkward cooldowns (25s and 15s for her Skill and Burst, respectively) do not align well with many team rotations. In these cases, it is better to either A) alternate between Burst and Skill each rotation or B) use Fischl’s Burst every rotation but only use her Skill every other.
ATK% or EM (if Aggravate)
Physical DMG% (if on-field)
For Aggravate teams specifically, ATK% Sands is similar to or better than EM Sands for most artifact/weapon combos, but EM Sands and EM substats are still viable. While an Electro Goblet is almost always preferred, a Physical Goblet can be used for on-field DPS builds focusing on Fischl’s C1.
ER (until requirement) > CRIT Rate/CRIT DMG > ATK%
|Any 2pc combo of ATK%/EM/Physical/Thundering Fury||A versatile build for any playstyle. 2pc EM sets are only an option for Aggravate teams; Physical DMG sets are an option for on-field DPS builds.|
|4pc Thundersoother (4TS)||Theoretically high damage ceiling for Electro-Charged and Aggravate teams, but not recommended because of its heavily conditional and niche passive.|
|4pc Gilded Dreams (4GD)||A great choice for Fischl’s reaction-centric builds. While its performance is close to 4TS in Aggravate and Electro-Charged teams, 4GD’s value drops drastically in other teams, making it a very situational set. Overall a good set to have if you have other characters who can make use of this set, but otherwise not worth farming for a full set.|
|4pc Tenacity (ToM)||A support set where Fischl can provide high uptime on the 4pc passive. Sacrifices Fischl’s personal damage for team buffs, but can provide a marginal overall upgrade to team DPS in ATK-scaling teams. Generally not recommended to farm for.|
|4pc Pale Flame (4PF)||Solid set for on-field DPS builds only. After the first rotation, Oz will benefit greatly from the 4pc ATK% buff.|
|Polar Star||Fischl’s BiS for all builds. Strong CRIT Rate main stat, strong passive that gives a hefty amount of ATK and Skill/Burst DMG.|
|Elegy of the End||Trades lower personal damage for team buffs and more ER, viable for off-field DPS builds.|
|Any other 5* Bow||Great stat sticks; most will be comparable to Polar Star if not better under specific conditions.|
|Alley Hunter||Comparable to 5* Bows for off-field DPS builds due to its easily obtainable stacks.|
|Prototype Crescent||A solid F2P option for all builds with the caveat that it requires hitting a weak point with a quick Aimed Shot to trigger its passive. Without its passive, this weapon’s value severely drops.|
|Fading Twilight||Another strong F2P but event-exclusive option. Off-field DPS Fischl can make good use of the ER and ATK it gives.|
|Stringless||An option for off-field DPS builds, particularly in Aggravate teams. Has a good passive at high refinements.|
|Rust||Since Aimed Shots are not an integral part of Fischl’s kit, this weapon performs decently for on-field DPS builds only.|
|Mitternachts Waltz||Aesthetically pleasing, but relevant only for on-field DPS playstyles that also maximize Oz uptime. Not recommended otherwise.|
Fischl is extremely versatile as she is able to fit into almost any team that needs Electro application, an Electro battery, or an off-field DPS with low field time.
|Xingqiu||Xingqiu’s off-field, single-target Hydro application matches well with Fischl’s off-field, single-target Electro application.|
|Sucrose||Sucrose is a good driver for off-field DPS Fischl’s A4, and she is also able to hold the 4VV artifact set and TTDS Catalyst.|
|Literally any Electro unit who would benefit from an Electro battery.||Includes Beidou, Yae, Cyno, Raiden, etc.|
|Literally any DPS who would benefit from off-field Electro application.||Practically the entire roster can synergize with Fischl due to her low field time, good particle generation, decent off-field damage and consistent Electro application which can enable a variety of Electro reactions (Overload, Electro-Charged, Quicken, etc.).|
This is not a comprehensive or ranked list of teams. The inclusion of a certain team, or lack thereof, does not necessarily indicate the power level of the team in question.
Electro-Charged (AKA “Taser”) teams typically include Fischl, a Hydro unit, and an Anemo unit. Usually, the Anemo unit drives the Electro-Charged reactions.
Fischl paired with a Pyro unit for Overload reactions.
When Fischl and a Hydro unit cause the Electro-Charged reaction, both an Electro and Hydro aura can coexist on the enemy. An instance of Pyro application on top of that causes both Overload and Vaporize reactions, hence the name “Overvape.”
A “Soup” team mixes Electro, Hydro, Pyro, and Anemo applications to trigger many reactions (Electro-Charged, Overload, Vaporize, Swirl), creating a soup of numbers and reactions. Fischl is a great enabler for the Electro reactions.
Fischl’s off-field Electro application paired with a Cryo unit allows her to trigger Superconduct for another Physical DPS.
While the current roster of Dendro units is small and teams utilizing the new Dendro reactions still need further testing, Fischl seems to have particular relevance in Aggravate teams due to her A4’s potential to trigger many Aggravates.
Although further investigations and team DPS calcs are still needed, Fischl may have a role in Hyperbloom teams. Oz’s tendency to avoid targeting Dendro Cores works in favor of Hyperbloom teams by allowing an Anemo unit to be the more consistent Hyperbloom trigger.
Fischl as an on-field DPS has many choices for flex slots, including: a Cryo unit for Superconduct, an Anemo unit for VV Shred, another off-field DPS, a buffer, or a healer/shielder.
