Great white wyrm is a type of monster in ADOM. They are very fast and extremely powerful late game opponents that breathe cold, and have a corresponding immunity to cold attacks. They are vulnerable to fire (prior to 1.2.0 they were not [1]). Like other elemental wyrms they can attack with glowing balls and confusion spells, can quickly heal themselves, always have a name, and drop a large pile of treasure when killed; great white wyrms expand on the usual magical pool of wyrms with the ability to drain stats in melee range.
