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.
The cave is a dangerous areas as it is multicombat and the trolls can hit high using both Melee and Ranged attacks; wearing a Neitiznot shield is advised as it lowers the max hit of the ranged trolls from 6 to 2. While en route to the cave, it's strongly advised to activate Protect from Melee since the melee trolls do more damage. You are unable to use the Dwarf multicannon within this cave, when attempting to set up the cannon it will state, "The air is too dank for you to set up a cannon here."
