A Sphere - ATK & BRV DMG are his key stats, and keep in mind that spheres that trigger based on weakness damage are reliable choices for him!
E Spheres - Paine sphere is insane for him, to further raise his ATK debuff to 90%. Also excellent spheres are Seymour, Irvine, Yuffie, Emperor!
Use his LD right away to apply his imperils down and his Power of Chaos effect up! This enables his Chaos Saber Shot.
Deadly Beast Flare (S1) maintains your Fire imperil.
Livewire Shot (S2) maintains your Thunder imperil.
Nightmare Shot (EX) should be used on cooldown to reapply his Nightmare debuff and maintain his Implanted Power buff. Using it also grants you a free skill. It's also one of his strongest hitting attacks.
Free skill can go to skills in Force Time, AA before Force Time, or ignore it during Force Time if you need to spam EX/LD.
Debuff Act Longer (AA) is perfect to add extra turns of duration to his debuffs and some party buffs on the side.
A Finale Chaotic (BT) shuts down enemy buffs and applies a debuffing aura to hinder enemies even more.
Daybreak (FR) inflicts most of his debuffs and provides a comfy 50% HP DMG & Limit for attacking debuffed enemies. It asks for:
Weakness BRV DMG on turn: +35%
Target a debufffed enemy on turn: +5% (per debuff, up to 40%)
Vincent needs help doing as much BRV damage as possible so BRV DMG Up, BRV DMG Limit up, BRV Steal up, Special BRV gains or Quina/Setzer will help with that.
You can pair him with a defensive utility as his debuffs along with other mitigation can help prevent scary damage done to the party!
