Ray of frost

Ray of frost is a spell cast by wizards, formerly a cantrip cast by both wizards and sorcerers, that is filled with cold energy. When cast, the spell conjures a frigid blast of cold, freezing white or blue air which then streaks towards its intended target.A magic missile is a bolt of pure force cast as a spell from its caster's fingertips.

Prior to the Spellplague ray of frost could be cast by both wizards and sorcerers and like all other spells, with the exception of invocations, ray of frost could not be cast at-will but had to be prepepared. Ray of frost was also considered a cantrip, or a very basic spell known to virtually all wizards, though it lost this status following the Spellplague, becoming a fully-ranked spell.
