Mist Form

The Form of Mist is a relic in Castlevania: Symphony of the Night that allows Alucard to assume the form of mist. This consumes MP and allows Alucard to be invulnerable to damage and to pass through certain gates. Alucard can normally only assume Mist form for a very brief moment, but there are additional relics that can be found that enhance this ability, including the Power of Mist that increases the amount of time that he can stay in Mist form and Gas Cloud which causes the mist form to damage enemies. In Castlevania: Judgment, Alucard's evade move involves him turning to mist briefly and reappearing further back or on the other side of his opponent.
