On Hard Mode, K'ril Tsutsaroth has a few changes in his mechanics, such as no longer having an explicit weakness to fire spells, as well as no longer using his Prayer smashing ability. Like all other hard mode God Wars Dungeon bosses, K'ril can bind players for 250 damage if they are under him. His health increases to 100,000 from 55,000, and he has three special attacks he can activate any time during the fight. He is still poisonous and his bodyguards act as normal.
