Snilloc's heat-seeking snowball

Unlike Snilloc's snowball, this spell did not require the caster to be able to see the intended target.

Components
The spell required verbal, somatic, and material components. The material required was either a chunk of ice or a piece of ivory.

History
The spell was developed as a minor modification of Snilloc's original spell by the drow wizard Dostrealt, who was blind. He had developed and collected a number of spells that did not rely on eyesight, so that his spellcasting efficiency was not hindered by his disability.
