Frost

Frost is a runic spell that appears in Ultima Underworld II.

Spell Description
The Avatar could learn the Frost spell by reading the notes of the unfortunate mage who had developed it in the Pits of Carnage. The unknown inventor of this incantation had hypothesized that a heat-reducing runic spell could be created either out of the runes An Flam Rel or In An Flam, but tragically discovered that the former incantation produced such a violent effect that it killed whomever cast it. Using the latter set of runes, the hero could invoke a wave of icy projectiles that would strike all surrounding them. Such a spell could be used to great effect against creatures naturally affiliated with heat, such as Fire Elementals.
