Toge Inumaki

A Blue Jujutsu support-debuffer whose specialty is amplifying the team's damage against weakened enemies. A recurring theme in his kit is that his debuffs scale stronger the lower the target's HP, so he gets better as a fight wears the enemy down — making him a strong finisher-enabler.

S3 is his main debuff: it stacks a sizable Blue Damage Received debuff on the target that grows as the enemy's HP drops, softening it for the rest of the Blue team.

S2 cuts the enemy's Jujutsu Stat (also scaling with low enemy HP), reducing their Jujutsu damage output while charging his own Ultimate — a mix of offense-debuff and defensive utility.

His Ultimate is his payoff: an AoE that applies the Blue Damage Received debuff to all enemies and deals heavy Jujutsu damage, ideal once the enemy team is already low and his scaling is at its strongest.

The cost of his kit is his own HP — most of his skills sacrifice health to cast (more against powerful enemies) — but he offsets this with multiple self-heal effects on his skills and a passive, so he sustains himself through the bleed.

Unusually for a support, he also packs attacker-level damage — but it is concentrated almost entirely in his Ultimate, which lands a heavy AoE Jujutsu hit; his other skills are mostly debuff tools with minor damage. His main value remains as a Blue debuffer-amplifier, and he is best in a Blue team that capitalizes on his Damage Received debuffs, especially in drawn-out fights where his low-HP scaling makes his debuffs hit their ceiling.
