The Ice Giants in the Asgarnian Ice Dungeon are uncommonly slay by F2P players due to the lack of valuable items these monsters drop. There is a reason why the Edgeville dungeon and Varrock dungeon is more abundant in F2P players because the Hill giants and Moss giants possess more beneficial items such as the Mossy Key and Giant Key. In order to clear the gap, I think an Ice giant boss should be implemented into the game. Similar to the Ice Giants, the boss will be larger, equipped with iced plate bodies with icy spikes protruding from the armor, vibrant red eyes, and wielding a long battle-axe-like weapon and a spiky shield. Additionally, the boss could have a special attack that could freeze the player if they're too close it. This idea could also be improve if it was introduced as a co-op boss fight for F2P.
