The Iosaur is an aggressive melee mob that spawns in Precasian Underground Dens. It is a hunter mob that can only be damaged if the player is level 52 or higher, and grants 200 hunter experience points when killed. It regenerates health very rapidly (about 30 (Heart.png×15) health per second), and also has high knockback as well as knockback immunity. This mob applies Slowness to the player on hit, which lasts for 2.5 seconds.

Trivia[edit | edit source]
