Best Drive Disc sets for Ju Fufu

Ju Fufu's best 4-piece set is King of the Summit. Swing Jazz, Proto Punk and Shockstar Disco are the alternatives, in that order.

King of the Summit Best in slot

4-piece: When the equipper is a Stun character and uses an EX Special Attack or Chain Attack, increases CRIT DMG of all squad members by 15%, and when the equipper's CRIT Rate is more than or equal to 50%, further increases CRIT DMG by 15%, lasting 15s. Repeated triggers reset the duration. Passive effects of the same name do not stack

2-piece: Increases Daze of attacks by 6%. Drops from Words and Weapons.
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.
Shockstar Disco

4-piece: Basic Attacks, Dash Attacks, and Dodge Counters inflict 20% more Daze to the main target

2-piece: Impact +6%. Drops from Hunter and Hound.

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

Impact +6%: Shockstar Disco
CRIT Rate +8%: Woodpecker Electro
ATK +10%: any of Hormone Punk or Astral Voice (they give the same bonus)
Energy Regen +20%: any of Swing Jazz or Moonlight Lullaby (they give the same bonus)
Increases Daze of attacks by 6%: King of the Summit

Ju Fufu 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%
Disk 5	ATK%
Disk 6	Impact = ATK%

Ju Fufu substat priority

Roll for CRIT Rate and Flat ATK first. A disc showing neither of those is rarely worth levelling for Ju Fufu, whatever else it has.

CRIT Rate (until 50% if using 4P King)
Flat ATK (until max. 3400)
CRIT DMG
PEN

Ju Fufu W-Engine and skill priority

Roaring Fur-nace S-rank, ATK sub-stat

Ju Fufu's signature is her best engine: lots of unconditional Daze and ATK, plus a 20% DMG Boost for the whole party that is easy to keep up permanently. Because her kit scales heavily with ATK, it makes her build the most forgiving while also giving the highest personal damage. With a high-quality build it is not mandatory, but it remains the top pick.

Skills to level first
