The Ice Troll King is the boss monster for The Fremennik Isles quest, and is the leader of the ice trolls. He is located on the northern part of the isles in his lair. He uses all three Combat styles, which includes a Melee attack, a Magic attack that freezes players, and a Ranged in which he will throw rocks at players and a special move, which will send players flying across the battleground.
He can be fought in the Nightmare Zone after the quest is complete.
The main thing to be careful about is his special attack that knocks players backwards. Players should use the Protect from Magic or Protect from Missiles prayer. Protect from Melee will result in the Troll King knocking the player into the cave wall for very high damage, which will repeat mutiple times, leaving them almost helpless; when players use either of the other prayers, it negates his attack, which knocks you back. Equip the Neitiznot shield (created during the quest). This, combined with the Protect from Magic prayer, should keep damage taken to a minimum as the shield will lower his Ranged Strength and he will not hit you for more than 1 or 2 Hitpoints with each hit. A one-handed dragon weapon or better is advised to defeat the King as he has high defensive stats.
Another way of defeating him is to simply use a Ring of recoil and to stand well away from him. This will cause him to use Ranged attacks dealing small amounts of damage to you and him. This method uses a lot of food and may still result in death if you are unlucky.
Another strategy is to use the Protect from Missiles prayer. If this prayer is used, the Troll King can only use magical and close-range (melee) attacks, and players can negate his attack, which knocks them backwards. However, he can still freeze players with his magical attack, which can be highly annoying and a waste of Prayer, and Protect from Missiles has a higher Prayer requirement. Bear in mind also that the damage taken from the Magic attack is not reduced nearly as much by equipment, if at all. For these reasons, Protect from Magic is generally recommended.
After the Ice Troll King is dead, decapitate him and take the head to the Burgher to show you have defeated him.

- Note: The King has a Magic attack similar to Ice Barrage; however, players can use Prayer to protect themselves.
