Best Drive Disc sets for Soldier 11

Soldier 11's best 4-piece set is Puffer Electro. Woodpecker Electro and Dawn's Bloom are the alternatives, in that order.

Puffer Electro Best in slot

4-piece: Ultimate DMG increases by 20%. Launching an Ultimate increases the equipper's ATK by 15% for 12s

2-piece: PEN Ratio +8%. Drops from Madman and Follower.
Woodpecker Electro

4-piece: Landing a critical hit on an enemy with a Basic Attack, Dodge Counter, or EX Special Attack increases the equipper's ATK by 9% for 6s. The buff duration for different skills are calculated separately

2-piece: CRIT Rate +8%. Drops from Tower and Cannon.
Dawn's Bloom

4-piece: Increases Basic Attack DMG by 20%. When equipped by an Attack character, using an EX Special Attack or Ultimate will further increase Basic Attack DMG by 20% for 25s. Repeated triggers reset the duration

2-piece: Increases Basic Attack DMG by 15%. Drops from Iron Law and Outlaws.

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 Soldier 11 can take it from whichever one you have spare pieces of:

CRIT Rate +8%: Woodpecker Electro
ATK +10%: any of Hormone Punk or Astral Voice (they give the same bonus)
CRIT DMG +16%: Branch & Blade Song
Fire DMG +10%: Inferno Metal
PEN Ratio +8%: Puffer Electro

Soldier 11 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	CRIT Rate > ATK% > CRIT DMG
Disk 5	PEN Ratio > ATK% > Fire DMG%
Disk 6	ATK%

Soldier 11 substat priority

Roll for CRIT Rate and CRIT DMG first. A disc showing neither of those is rarely worth levelling for Soldier 11, whatever else it has.

Anomaly Proficiency
