Basic Thwack

Deals Quantum DMG equal to 100% of Seele's ATK to a single enemy. A straightforward attack used when Skill Points are scarce or to trigger the A6 trace action advance.

100% of ATK
Skill Sheathed Blade

Increases Seele's SPD by 25% for 2 turns and deals Quantum DMG equal to 220% of her ATK to a single enemy. This is her primary damage tool and should be used almost every turn. The SPD buff is easy to maintain indefinitely.

220% of ATK
Ultimate Butterfly Flurry

Seele immediately enters the Buffed state and deals Quantum DMG equal to 425% of her ATK to a single enemy. The Buffed state is active for the Ultimate hit itself and persists for 1 additional turn, meaning every Ultimate always benefits from the full Buffed multipliers.

425% of ATK
Talent Resurgence

Upon defeating an enemy with Basic ATK, Skill, or Ultimate, Seele enters the Buffed state and receives a true extra turn (not an action advance; buffs do not tick down). While Buffed, all attacks deal +80% DMG for 1 turn. Kills in the extra turn cannot chain another Resurgence.

+80% DMG while Buffed
Technique Phantom Illusion

After use, Seele gains Stealth for 20 seconds, making her undetectable by enemies in the overworld. When she initiates combat from Stealth, she immediately enters the Buffed state, a free Resurgence proc at the very start of the fight.

Skill is her primary damage source and SP engine. Talent governs the Resurgence Buffed state DMG bonus; both are equally important. Ultimate rounds out the burst window. Basic is rarely used at high investment.

The Hell Where Ideals Burn
The Hell Where Ideals Burn
Archer's signature. Provides a very large ATK buff and CRIT Rate when the team's max Skill Points is 6 or higher; requires Sparkle on the team. Consistently best on Seele with Sparkle due to the massive ATK multiplier, though it needs a short ramp-up period at the start of combat.
Sparkle teams
#1
In the Night
In the Night
Seele's own signature. Raises CRIT Rate and scales Basic ATK / Skill DMG for every 10 SPD exceeding 100, up to 6 stacks. Also boosts Ultimate CRIT DMG. Best in most non-Sparkle builds; slightly underutilized unless E2 is unlocked since her top build does not focus on stacking SPD.

#3
Swordplay
Swordplay
Excellent 4-star option at S5. Stacks up to 16% DMG per hit on the same target, capping at 5 stacks for a total of 80% bonus DMG. Performs best in single-target boss fights where Seele stays on one target throughout the whole fight.

Only Silence Remains
Only Silence Remains
Solid 4-star providing ATK% and bonus CRIT Rate when 2 or fewer enemies are on the field. Works best in boss encounters. Performance drops in waves with more than 2 enemies present.

Cruising in the Stellar Sea
Cruising in the Stellar Sea
Available from Herta's Store, making it permanently accessible. Boosts CRIT Rate and gains extra CRIT Rate against enemies below 50% HP. Provides ATK after scoring a kill, great synergy with Seele's kill-focused kit.

Genius of Brilliant Stars
Genius of Brilliant Stars
Her best-in-slot cavern set. The 2-piece gives +10% Quantum DMG. The 4-piece ignores 10% of the target's DEF, plus an additional 10% DEF ignore if the target has Quantum Weakness, for a total of 20% DEF ignore against Quantum Weak enemies. Pairs directly with Silver Wolf's Quantum implant for consistent maximum DEF shred.

Scholar Lost in Erudition
Scholar Lost in Erudition
Competitive alternative providing CRIT Rate and boosting Skill and Ultimate DMG by 20%, with an extra 25% Skill DMG boost after using the Ultimate. Can outperform Genius in teams without additional DEF shred sources; once any DEF shred is added to the team, Genius pulls ahead.

2-piece Mix (Flex)
Combining 2-piece Genius of Brilliant Stars with 2-piece Scholar, Musketeer of Wild Wheat, Prisoner in Deep Confinement, or The Wind-Soaring Valorous. Use this route if you have well-rolled off-pieces that beat poorly-rolled full-set alternatives.

Rutilant Arena
Rutilant Arena
Best planar set for Seele. Grants +8% CRIT Rate, and when CRIT Rate reaches 70% or higher, Basic ATK and Skill DMG increase by 20%. Seele easily reaches the 70% threshold with proper build, making this bonus near-permanent in practice.

Firmament Frontline: Glamoth
Firmament Frontline: Glamoth
Strong alternative. Provides 12% ATK and bonus DMG when SPD is 135 or higher (12% bonus), or 160+ (18% bonus). At 160+ SPD, this set edges ahead of Rutilant Arena. Best suited for high-SPD builds leveraging the In the Night signature or E2.

Backup option. Grants +8% CRIT Rate and a 15% boost to Ultimate DMG when CRIT Rate is at 50% or higher. Useful if your Rutilant or Glamoth pieces have poor substats.

Eidolons

E 1
Extirpating Slash
When dealing DMG to an enemy whose HP percentage is 80% or lower, CRIT Rate increases by +15%. Nearly always active since most encounters begin with enemies already below 80% HP after the first hit, or Seele will drop them below that threshold quickly.
Recommended Pull
E 2
Dancing Butterfly
The SPD Boost effect from Seele's Skill can now stack up to 2 times (up to +50% SPD). This directly enables the Firmament Frontline: Glamoth planar set at its highest tier and makes In the Night's SPD-scaling bonus more valuable. Allows Seele to reach breakpoints for additional actions.
Solid Upgrade
E 3
Dazzling Tumult
Skill level +2 (max 15) and Talent level +2 (max 15). Both upgrades boost her primary damage sources: Skill multiplier increase and the Resurgence Buffed state DMG bonus. Noticeably increases overall damage output.
High Pull Value
E 4
Flitting Phantasm
Seele regenerates 15 Energy each time she defeats an enemy. Directly reduces the turns needed between Ultimates, keeping Seele in Buffed state more often during multi-target encounters or when she can chain kills.
Good Passive
E 5
Piercing Shards
Ultimate level +2 (max 15) and Basic ATK level +1 (max 10). Increases the Ultimate's multiplier on what is already her largest single hit. Incremental but meaningful improvement to burst damage.
Incremental
E 6
Shattering Shambles
After using her Ultimate, inflicts Butterfly Flurry on the target for 1 turn. Enemies with Butterfly Flurry take additional Quantum DMG equal to 15% of Seele's Ultimate DMG every time they are attacked by any ally. If the afflicted enemy is killed by Butterfly Flurry DMG from another ally's attack, Seele's Talent will not trigger. Simulation data shows E6 increases damage by roughly 82% from E0 baseline.
Massive Upgrade

Major Traces

Nightshade
Ascension 2
When Seele's current HP percentage is 50% or lower, reduces the chance of being targeted by enemies. A defensive survival trace that keeps Seele safer in situations where she drops to low HP, reducing the risk of her being focused down before she can recover.
Lacerate
Ascension 4
While Seele is in the Buffed state, her Quantum RES PEN increases by 20%. Resistance penetration is one of the most powerful damage multipliers in the game as it affects a separate calculation from DMG%, CRIT, and ATK scaling. This trace is a core reason why Seele can deal meaningful damage against non-Quantum Weak enemies.
Rippling Waves
Ascension 6
After Seele uses a Basic ATK, her next action is Advanced Forward by 20%. Provides a small but consistent action economy bonus whenever Basic ATK is used, allowing more turns in a given cycle when Skill Points are tight.

Frequently Asked Questions

Yes, Seele is A Tier and remains a capable single-target DPS who clears all endgame content with proper investment. However, she requires increasingly heavy investment to keep up as enemy HP pools grow. The key challenge is maintaining the ability to one-shot trash mobs, which fuels her Resurgence extra turns. If you can't consistently one-shot adds, her performance drops significantly. With Sparkle and good Relics, she still performs well in Memory of Chaos and Apocalyptic Shadow.
Swordplay at S5 is the best free-to-play option for single-boss encounters where Seele stays on one target. Only Silence Remains at S5 is strong if the fight stays at 2 or fewer enemies. Cruising in the Stellar Sea from Herta's Store is permanently accessible and synergizes well with Seele's kill-focused kit through the post-kill ATK buff.
When Seele defeats an enemy with her Basic ATK, Skill, or Ultimate, she immediately enters the Buffed state and gains a true extra turn, not an action advance. The key distinction is that buffs do not tick down after extra turns, unlike action advances. This means she retains the full duration of SPD boosts and other timed buffs. The extra turn itself cannot trigger another Resurgence, so she cannot chain infinitely.
Silver Wolf is highly recommended but not mandatory. Her Quantum implant ensures enemies always have Quantum Weakness, enabling the full 20% DEF ignore from the Genius of Brilliant Stars 4-piece set. Without Silver Wolf, Genius loses half its set bonus against non-Quantum Weak enemies. In that scenario, Scholar Lost in Erudition becomes a stronger alternative relic set, and you can consider other supports like Sparkle, Robin, or Tingyun instead.
Aim for 80%+ CRIT Rate. In practice, many players push toward 100% because Seele's damage is so tightly tied to critting every hit that even one non-crit on a key Skill or Ultimate hit can feel like a large loss. Fu Xuan's Skill provides an extra ~12% CRIT Rate to the team which helps significantly. Use CRIT Rate on the Body main stat or CRIT DMG depending on your substat rolls, keeping a 1:2 CRIT Rate to CRIT DMG ratio as a rough target.
E1 adds 15% CRIT Rate against enemies below 80% HP, which is nearly always active and provides strong value with no build changes required. E2 enables SPD stacking and the Glamoth planar set at full effectiveness. E3 is the biggest power spike, boosting both the Skill and Talent levels which directly scale her damage. E6 roughly doubles her damage from E0 in simulations, but spending six limited 5-star copies on one character is only for dedicated Seele mains.
