Grace Build: Best Drive Discs & Stats (ZZZ)

Grace is an S-rank Anomaly agent in Zenless Zone Zero. This Grace Drive Disc build lists the sets, main stats and substats to aim for, and the Area Patrol stage that drops them, as of version 3.2.

4-piece: Thunder Metal
2-piece: PEN Ratio +8%, Anomaly Mastery +8%, Anomaly Proficiency +30 or ATK +10%
Disk 4: Anomaly Proficiency
Disk 5: PEN Ratio
Disk 6: Anomaly Mastery
Substats: Anomaly Proficiency > ATK% > PEN
W-Engine: Timeweaver

Best Drive Disc sets for Grace

Grace's best 4-piece set is Thunder Metal. Chaos Jazz is the alternative.

Thunder Metal Best in slot

4-piece: As long as an enemy in combat is Shocked, the equipper's ATK is increased by 28%

2-piece: Electric DMG +10%. Drops from Hunter and Hound.
Chaos Jazz

4-piece: Fire DMG and Electric DMG increases by 15%. While off-field, EX Special Attack and Assist Attack DMG increases by 20%. When switching on-field, this buff continues for 5s, and this continuation effect can trigger once every 7.5s

2-piece: Anomaly Proficiency +30. Drops from Hunter and Beast.

2-piece options

For the 2-piece slot the bonus matters, not the set's name. Several sets share the same 2-piece bonus, so Grace can take it from whichever one you have spare pieces of:

PEN Ratio +8%: Puffer Electro
Anomaly Mastery +8%: Phaethon's Melody
Anomaly Proficiency +30: any of Freedom Blues, Chaos Jazz or Feathered Fate (they give the same bonus)
ATK +10%: any of Hormone Punk or Astral Voice (they give the same bonus)

Grace main stats: Disk 4, 5 and 6

Disks 1 to 3 always roll HP, ATK and DEF as their main stat, so the choice is on 4, 5 and 6. A > means "better than"; = means the two are about as good.

Slot	Main stat, best first
Disk 4	Anomaly Proficiency > ATK%
Disk 5	PEN Ratio > Electric DMG% > ATK%
Disk 6	Anomaly Mastery

Grace substat priority

Roll for Anomaly Proficiency and ATK% first. A disc showing neither of those is rarely worth levelling for Grace, whatever else it has.

Anomaly Proficiency
ATK%
PEN
Flat ATK

Yanagi's signature delivers high ATK, unconditional Electric Anomaly Buildup Rate, and a big helping of Anomaly Proficiency plus Disorder damage once Anomaly Proficiency reaches 375 or more. An outstanding fit for every Electric Anomaly Agent, Grace included.

Questions

What is the best Drive Disc set for Grace?

Thunder Metal 4-piece, with Chaos Jazz as the alternative. For the 2-piece, any set with PEN Ratio +8%, Anomaly Mastery +8%, Anomaly Proficiency +30 or ATK +10% works.

What main stats should Grace use on Disk 4, 5 and 6?

Disk 4: Anomaly Proficiency > ATK%. Disk 5: PEN Ratio > Electric DMG% > ATK%. Disk 6: Anomaly Mastery. Disks 1 to 3 have fixed main stats (HP, ATK and DEF), so only their substats matter.

What substats does Grace need?

In priority order: Anomaly Proficiency, ATK%, PEN, Flat ATK. The first two are what make a disc worth levelling for Grace; the rest are tiebreakers.

Where do I farm Grace's Drive Discs?

Thunder Metal drops from the Hunter and Hound Area Patrol stage, alongside Shockstar Disco. Each run at Lv.60 costs 60 Battery Charge and splits its S-rank discs between the two sets.
