Spreading Frost

is a boss in the Temple of Heorot and the guard of the portal to Farwood.

Tactics
Spreading Frost is a large version of the Ice Elemental with the added ability to clone itself for limited duration and summon an ice vortex. The clones can independently use their own abilities, at times winding up two or three Frost Blasts at a time, making the opponent particularly dangerous for an unwary player.
