The great wyrm is a monster in Might and Magic VI: The Mandate of Heaven. It is stronger than the wyrm and giant wyrm. Great wyrms have more hit points and a higher armor class than giant wyrms, and a greater resistance to magical damage. Like wyrms and giant wyrms, they are immune to poison, and have some resistance to most other type of damage, but have no resistance to physical attacks. They can be encountered in Caves of the Dragon Riders and Dragonsands.
