The Ice Troll Caves can be found north of Jatizso and Neitiznot. To enter the caves, players need to have completed parts of The Fremennik Isles quest. Six Honour guards can be found fighting ice trolls in the northern most cave. The Ice Troll King is also found in this cave. After the completion of The Fremennik Isles, the caves can only be accessed using the western entrance, and the Ice Troll King no longer appears.
Although Yak-hide armour and a Fremennik round shield from the quest may offer some Defence against the trolls' attacks, the cave is a multicombat area and dangerous as the trolls can hit high using both Melee and Ranged attacks. While en route to the cave, it's strongly advised to activate Protect from Melee since the melee trolls do more damage. If using a Dwarf multicannon during a Slayer assignment, it is important to be wary of high damage and low drops.
