The Mystic Urn is an artifact in Heretic and Hexen. It looks like a grey urn with a golden ankh on it. Using a Mystic Urn restores the player to full health. Unlike Doom's Soulsphere, it can be carried around until needed, but cannot raise the player's health above 100, which makes it similar to the Berserk pack but without the pack's fist improvement power. On skill 1, the Mystic Urn is sometimes used at death, preventing you from dying.
