Glacial Rift creates a twisting portal to the elemental realm, and allows the chilling Frost Weaver to enter through to your dungeon, tethered to the defense.

The Frost Weaver is a powerful minion who will slow nearby enemies with its arctic attacks, and upon death will explode in an icy blizzard straight from the realms which is came, freezing nearby enemies solid for a period of time.

Glacial Rift is one of the defenses available within the Vein of Sloth.
