Rime Hulk

Rime Hulk
Rime hulks are a withered branch of the frost giant family tree, descended from ancient giants who withdrew from the world and succumbed to their elemental nature. Most rime hulks dwell in the Frostfell, the 'plane of ice' that forms the border between the Elemental Planes of Air and Water. Others lurk in isolated rifts in enormous polar glaciers.
Smaller and weaker than their ancestors, rime hulks are roughly formed masses of frost and ice. Their vaguely giant-shaped physical forms are unstable, constantly breaking apart and reforming as clouds of frost billow off them. As a rime hulk moves, it leaves a trail of ice that can freeze enemies in place. When it dies, a rime hulk explodes in a burst of frost.
In all seriousness, though, it's best not to get caught up in what these hulks were or might have become had things gone differently for them. They're dangerous, and most of them do not wish you well. Act accordingly.
