Icefiend

Icefiends are low level NPCs found at the Ice mountain near Barbarian village. They can be assigned as an easy task by Chaeldar, giving 53 Slayer experience when killed.
They have a combat level of 18 and have 9 Hitpoints. They freeze players when they attack, immobilizing them for a few seconds. When players are doing the Barbarian assistance quest, the Icefiends will become aggressive, freezing them during their rescue mission.

Icefiends only drop ashes.
