Best Drive Disc sets for Seth

Seth's best 4-piece set is Astral Voice. Swing Jazz, Proto Punk and Freedom Blues are the alternatives, in that order.

Astral Voice Best in slot

4-piece: Whenever any squad member enters the field using a Quick Assist, all squad members gain 1 stack of Astral, up to a maximum of 3 stacks, and lasting 15s. Repeated triggers reset the duration. Each stack of Astral increases the DMG dealt by the character entering the field using a Quick Assist by 8%. Passive effects of the same name do not stack

2-piece: ATK +10%. Drops from Monster Duet.
Swing Jazz

4-piece: Launching a Chain Attack or Ultimate increases all squad members' DMG by 15% for 12s. Passive effects of the same name do not stack

2-piece: Energy Regen +20%. Drops from Monster and Weirdo.
Proto Punk

4-piece: When any squad member triggers a Defensive Assist or Evasive Assist, all squad members deal 15% increased DMG, lasting 10s. Passive effects of the same name do not stack

2-piece: Increases Shield effect by 15%. Drops from Hunter and Beast.
Freedom Blues

4-piece: When an EX Special Attack hits an enemy, reduce the target's Anomaly Buildup RES to the equipper's Attribute by 20% for 8s. This effect does not stack with others of the same attribute

2-piece: Anomaly Proficiency +30. Drops from Sharp Fang and Blunt Axe.

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 Seth can take it from whichever one you have spare pieces of:

Energy Regen +20%: any of Swing Jazz or Moonlight Lullaby (they give the same bonus)
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)
Impact +6%: Shockstar Disco
Increases Shield effect by 15%: Proto Punk

Seth 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	ATK% > Anomaly Proficiency
Disk 5	ATK% > Electric DMG%
Disk 6	Energy Regen = Anomaly Mastery

Seth substat priority

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

Anomaly Proficiency

Seth W-Engine and skill priority

Peacekeeper - Specialized A-rank, ATK sub-stat

Easily Seth's best engine: unconditional ATK% for bigger shields, a big chunk of extra Energy Regen for his burst combo, and a massive Anomaly Buildup boost on two of his strongest attacks, ideal in Disorder teams.

These agents compete with Seth for the same set, which is worth knowing before you hand a good piece to one of them.

Questions

What is the best Drive Disc set for Seth?

Astral Voice 4-piece, with Swing Jazz, Proto Punk or Freedom Blues as the alternatives. For the 2-piece, any set with Energy Regen +20%, Anomaly Proficiency +30, ATK +10%, Impact +6% or Increases Shield effect by 15% works.

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

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

What substats does Seth need?

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

Where do I farm Seth's Drive Discs?

Astral Voice drops from the Monster Duet Area Patrol stage, alongside Branch & Blade Song. Each run at Lv.60 costs 60 Battery Charge and splits its S-rank discs between the two sets.
