Ice Elementals

It is not exactly clear what kind of magical creatures ice elementals are.

Description
While the exact nature of these creatures is unknown, what is clear, however, is that their attacks are hard-hitting and can kill a lesser man with one strike. Additionally, their bodies, due to being created from hard ice, are difficult to destroy. Logically, fire - regular fire, not cold-fire - is therefore their weakness. Only the best warriors should dare to battle it out with these merciless constructs.

They are found in the places they were told to guard.

Trivia

 * The final battle of Ultima VII Part Two is against a number of these, conjured by the Order Serpent. This can hit players unprepared, as otherwise there aren't any battles at the Shrine of Balance.
