Release3.3
Cipher is a Quantum Nihility support who marks one enemy as the "Patron", strikes it with a follow-up attack whenever an ally hits it, and keeps a tally of the damage her team deals. Her Ultimate releases that tally as True DMG, and simply having her on the field makes every enemy take 40% more DMG. She fits almost any team, as long as she reaches 170 SPD and you time her Ultimate yourself.
Support / Sub DPS
Light Cones
Lies Dance on the Breeze BiS
5★
Signature and best in slot: 18% SPD makes 170 easy, and her attacks lower all enemies' DEF by 16% (24% at 170 SPD). It re-applies on every attack, which feeds Acheron, and it is a strong Light Cone for other Nihility characters too.
SPD +18%; attacks inflict Bamboozle on all enemies (DEF -16% for 2 turns), plus Theft (DEF -8%) at 170 SPD or more.
Resolution Shines As Pearls of Sweat
4★
Best alternative at S5: DEF reduction on hit, but weaker, shorter, with no SPD and a lower hit chance (aim for 67% Effect Hit Rate).
Hits have a 60% base chance to Ensnare enemies, lowering their DEF by 12% for 1 turn.
Holiday Thermae Escapade
4★
4★ option: a DMG bonus and a Vulnerability debuff on every attack.
DMG +16%, and attacks inflict Vulnerability, making the target take 10% more DMG for 2 turns.
Boundless Choreo
4★
4★ option for her personal damage: CRIT Rate, and CRIT DMG against DEF-reduced or Slowed enemies.
CRIT Rate +8%, and CRIT DMG +24% against Slowed or DEF-reduced enemies.
Good Night and Sleep Well
4★
4★ fallback: more DMG for each debuff on the target, easy to stack in debuff teams.
DMG +12% per debuff on the target (up to 3 stacks), DoT included.
Relics
Pioneer Diver of Dead Waters
×4
Most used and most consistent set for her personal damage, if you can reach 170 SPD without SPD sets.
Set effects
2pIncreases DMG dealt to enemies with debuffs by 12%.
4pIncreases CRIT Rate by 4%. The wearer deals 8%/12% increased CRIT DMG to enemies with at least 2/3 debuffs. After the wearer inflicts a debuff on enemy targets, the aforementioned effects increase by 100%, lasting for 1 turn(s).
Messenger Traversing Hackerspace
×2
Sacerdos' Relived Ordeal
×2
Two 6% SPD bonuses: the easiest way to hit 170 SPD. Diviner of Distant Reach or Warrior Goddess of Sun and Thunder (2-piece) work the same way.
Set effects
2pIncreases SPD by 6%.
2pIncreases SPD by 6%.
Genius of Brilliant Stars
×4
Alternative to Pioneer: DEF ignore, even better against Quantum-weak enemies.
Set effects
2pIncreases Quantum DMG by 10%.
4pWhen the wearer deals DMG to the target enemy, ignores 10% DEF. If the target enemy has Quantum Weakness, the wearer additionally ignores 10% DEF.
Eagle of Twilight Line

Debuffer build with an Energy Regeneration Rope: each Ultimate advances her action.
Set effects
2pIncreases Wind DMG by 10%.
4pAfter the wearer uses their Ultimate, their action is Advanced Forward by 25%.
Planar ornaments
Firmament Frontline: Glamoth
×2
Best for Sub DPS Cipher: she naturally exceeds 160 SPD, so the full DMG bonus is always active.
Set effects
2pIncreases the wearer's ATK by 12%. When the wearer's SPD is equal to or higher than 135/160, the wearer deals 12%/18% more DMG.
Lushaka, the Sunken Seas
×2
Best for pure support: Energy Regeneration and ATK for the ATK-scaling DPS in the first slot.
Set effects
2pIncreases the wearer's Energy Regeneration Rate by 5%. If the wearer is not the first character in the team lineup, then increases the ATK of the first character in the team lineup by 12%.
Penacony, Land of the Dreams
×2
Top pick in Quantum teams (Archer, Rin Tohsaka, Sparkle): Energy Regeneration and DMG for same-element allies.
Set effects
2pIncreases wearer's Energy Regeneration Rate by 5%. Increases DMG by 10% for all other allies that are of the same Type as the wearer.

Major Trace priority: Empyrean Strides (A2) > 300 Rogues (A4) > Sleight of Sky (A6) — you need all three. Never trade SPD for damage stats if it drops her below 170.
Teams
Recommended teams
Archer Quantum
Her most successful team on Prydwen: an all-Quantum lineup where Sparkle fuels Archer's Skill chains, every hit on the Patron feeds Cipher's tally, and Penacony, Land of the Dreams works on everyone.
Acheron
Cipher counts as a Nihility teammate for Acheron, and with her signature every attack, follow-ups included, applies a debuff that feeds Acheron's Ultimate. Jiaoqiu can replace Mortenax Blade.
Guide
How to play
How she works
- Patron (Talent). If no enemy is the Patron, the enemy with the highest Max HP becomes it; the main target of her Skill or Ultimate also becomes the Patron. When another ally attacks the Patron, Cipher launches a follow-up attack on it (once per turn, reset at the start of her turn).
- The tally. Cipher records 12% of the non-True DMG allies deal to the Patron, and 8% of the damage dealt to other enemies with her A4 (300 Rogues). Overflow DMG is never counted, so a tally reflects the real HP enemies lost.
- Empyrean Strides (A2). At 140/170 SPD she gains 25%/50% CRIT Rate and her tally grows by 50%/100% — at 170 SPD she records 24% of the damage on the Patron and 16% on other enemies.
- Ultimate (130 Energy). Deals 25% of the tally as True DMG to the target, then splits the remaining 75% evenly between the target and its adjacent enemies. Against a single enemy, all of it lands on that enemy. The tally is then cleared.
- Sleight of Sky (A6). While she is on the field, all enemies take 40% more DMG, and her follow-up attack gains 100% CRIT DMG.
Rotation
- Use her Technique: the opening hit on all enemies adds 200% more to the tally.
- Mostly use Basic ATK to generate Skill Points; use her Skill when you have Skill Points to spare or to move the Patron onto a priority target (it also Weakens enemies and raises her ATK by 30%).
- Hold the Ultimate until the tally is big, then fire it at the boss or at the start of a new phase. Damage stored during an easy first wave can be carried over to delete the next one.
Tips
- 170 SPD in combat is mandatory: below it you lose half of her tally and half of her CRIT Rate bonus.
- Play her manually: Auto mode fires the Ultimate as soon as it is ready and wastes most of the stored damage. Exception: with Feixiao, frequent Ultimates simply mean more attacks.
- The more HP enemies have, the more she can store — she is at her best against tanky bosses.
Strengths
- Permanent 40% DMG taken aura on all enemies, with no upkeep
- Stores the team's damage for a True DMG nuke that ignores RES and damage reduction
- Very fast and Skill Point friendly
- Fits almost any team as a close second-best support
- Good Toughness damage for a support
Weaknesses
- Low personal damage without heavy investment
- Needs 170 SPD to unlock her full power
- Loses much of her value on Auto mode
- Few good Light Cones besides her signature
