Negation (lower lets more through), and how much more or less damage that type deals than Standard does.

From full HP with that status alone; thresholds grow after each proc. Frostbite's extra 20% damage taken isn't counted.

Attacks, their hits, parry and block, grabs and damage are read from the boss's animation events and attack data; when it picks them, from its battle script. Attack names follow the names players commonly use; the rest are described from their hits.
