Agni

Agni is the fire-charged branch of the Kodama line. It is a bright hovering core that escalates much faster than an ordinary Kodama and ends fights with an explosion.

It becomes aggressive at a much lower anger threshold, burns on hit, and detonates on death. The burst is the part to respect. Even a clean kill can still punish melee range if you stay on top of it.

Agni appears in Anger, Prison, Aether, and Rosary. It always drops fire, so the fight has a straightforward payoff if you can finish it without standing in the blast.
