Jade is a Quantum Erudition damage dealer and support built for AoE teams. Her Skill turns an ally into the Debt Collector: +30 SPD, and each of their attacks adds Quantum Additional DMG to every enemy hit while charging her Talent. Every 8 enemies hit, she fires an AoE Follow-Up ATK that stacks Pawned Asset for CRIT DMG and ATK. She shines in Pure Fiction, especially next to The Herta.

Relics
Poet of Mourning Collapse

Top choice as long as she has no SPD: Quantum DMG and 32% CRIT Rate. Avoid it if her Skill must hit a precise SPD breakpoint.
Set effects

4pDecreases the wearer's SPD by 8%. Before entering battle, if the wearer's SPD is lower than 110/95, increases the wearer's CRIT Rate by 20%/32%. This effect applies to the wearer's memosprite at the same time.
Genius of Brilliant Stars
×4
Best against Quantum-weak enemies thanks to its DEF ignore; weaker otherwise.
Set effects

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.
The Ashblazing Grand Duke
×4
Generic option: her multi-hit Follow-Up ATKs stack its ATK bonus easily.
Set effects
2pIncreases the DMG dealt by Follow-Up ATK by 20%.
4pWhen the wearer uses a Follow-Up ATK, increases the wearer's ATK by 6% for every time the Follow-Up ATK deals DMG. This effect can stack up to 8 time(s) and lasts for 3 turn(s). This effect is removed the next time the wearer uses a Follow-Up ATK.

×2
Most used: Follow-Up ATK DMG and CRIT DMG, quickly stacked in Follow-Up teams.

×2
Slightly stronger with another Erudition character (The Herta, Himeko • Nova): ATK and +12% CRIT Rate.

The Herta Erudition
Her best use: make The Herta the Debt Collector. Jade gives her +30 SPD and some of the most frequent stacks and Energy of any Erudition partner, and deals great damage herself in Pure Fiction.
Himeko • Nova
Himeko • Nova's frequent AoE hits charge Jade quickly, and both Erudition characters activate Izumo Gensei and Takama Divine Realm.
Free-to-play
Herta's AoE Follow-Up ATKs and Jade's ping-pong off each other, while the free Trailblazer (Remembrance) adds CRIT DMG and Lynx heals.
Guide
How to play
How she works
- Acquisition Surety (Skill). One ally becomes the Debt Collector for 3 turns (the duration ticks down at the start of Jade's turns) and gains +30 SPD. After each of their attacks, Jade deals Quantum Additional DMG (25% of her ATK) to every enemy hit, at the cost of 2% of the Debt Collector's Max HP. She can't recast it while a Debt Collector exists.
- Fang of Flare Flaying (Talent). She gains 1 Charge for every enemy hit by her or by the Debt Collector. At 8 Charge, she launches an AoE Follow-Up ATK and gains 5 Pawned Asset stacks (+2.4% CRIT DMG each, up to 50 stacks, i.e. +120%).
- Vow of the Deep (Ultimate, 140 Energy). AoE damage, and her next 2 Talent Follow-Up ATKs get +80% DMG multiplier.
- Traces. Reverse Repo (A2) gives Pawned Asset when enemies enter combat and 3 more at the start of each Debt Collector turn, Collateral Ticket (A4) advances her by 50% at the start of battle, and Asset Forfeiture (A6) adds +0.5% ATK per Pawned Asset stack.
Rotation
- Use her Technique: enemies with Blind Fealty won't attack, and the battle starts with AoE damage and 15 Pawned Asset stacks.
- Skill on the ally who hits the most enemies the most often (The Herta, Himeko • Nova…) and recast it whenever it expires; otherwise use her Blast Basic ATK to save Skill Points.
- Use her Ultimate whenever it's ready, ideally before a flurry of Follow-Up ATKs.
Tips
- Charge depends on the number of enemies hit: she is at her best against crowds (Pure Fiction) and needs E1 to shine against one or two targets.
- With 4-piece Poet of Mourning Collapse, take no SPD at all: her base 103 SPD drops to 94.8, below the 95 threshold for the full 32% CRIT Rate.
- The Debt Collector's HP drain is small, but keep a healer or shielder in the team.
Strengths
- Top-tier performance in Pure Fiction
- Great synergy with AoE and AoE Follow-Up damage dealers
- A strong flat +30 SPD buff on one ally
- Slots easily into existing AoE teams
- One of the best partners for The Herta
Weaknesses
- Below average outside Pure Fiction for a limited 5★ (unless paired with The Herta)
- Highly variable damage output
- Relies on her E1 against one or two targets
