Damage calculator

Pick a party member and a skill, say how the QTEs went, and see each hit's damage against an enemy, with and without a critical hit.

How this works: each skill's hits come from its battle sequence (one per action effect, cut short where a missed QTE ends the combo) and its script's multipliers from the skill balancing table. Every hit then runs the game's damage steps: Attack, Defense, critical hit ×1.5, the target's Skill multiplier, affinity, damage bonuses, the skill multiplier, the 9,999 limit (lifted completely by the Painted Power Picto or Lumina) and rounding.

What the game does with a hit

Attack, then Defense. The hit starts from the attacker's Attack, rounded up. Defense reduces it to Attack² ÷ (Attack + 2 × Defense); no enemy in this build has any Defense, so this step changes nothing.
Critical hit. ×1.5, more with a skill or Lumina that raises critical damage. The chance is the crit rate plus any bonus chance, out of 100.
Target and affinity. Some enemies take more or less from Skills and base attacks. A weakness gives ×1.5 damage and ×2 break damage, a resistance ×0.5 both; nullified elements deal nothing and absorbed ones heal the enemy by the attacker's Attack.
Damage bonuses. Buffs, Pictos and Luminas: their multipliers multiply, their "increased damage" percentages add up first (two +30% make ×1.6).
Skill multiplier. The skill's base value × (1 + 10% per Good QTE, 20% per Perfect, for most skills) × its overcharge, together with Mark (×1.5) and Defenceless (×1.25) on the target.
Limit, Shields, rounding. A party member's hit stops at 9,999 unless Painted Power is equipped, which removes the limit altogether; a Shield absorbs a whole hit; the rest rounds to the nearest whole number, halves up.

Flying enemies dodge 80% of Skill and base attack hits; the numbers are for the hits that land. Skills that pick random enemies are shown for hits on the chosen one.

Damage skills not in the calculator: Mayhem: each hit takes its element and multiplier from Lune's Stain queue, consumed one Stain per hit from the end. Storm Caller: its damage comes later, at the end of enemy turns and when they are hit, not from the cast.
