Strategy

Main article: Callisto/Strategies

Callisto primarily attacks with melee, but he also uses ranged against players that he cannot reach. His melee attack deals massive damage and shatters into other players near his current target. His melee attack has a minimum hit of 35 . At specific health intervals, he can deploy ghostly bear traps that bind players that step into one. When Callisto does this, he will become unfrozen regardless of any remaining time on the freeze. Callisto will occasionally send out a slow magic attack towards the player. If the player is not praying Protect from Magic when the attack reaches the player, this will result in the player being knocked back and temporarily stunned, in addition to potentially taking a large amount of damage.

Protection prayers will negate all ranged and magic damage of his attacks, but Protect from Melee will only reduce the damage by ~50%.
