The giant worm is a unique monster in Dark Messiah of Might and Magic. It is an enormous, heavily armored creature that dives at its opponent with its jaws spread wide, and can also spit poison. It is vulnerable to fire.
The giant worm is encountered in Fire in the Blood. It's too powerful to fight, and to engage it in melee would be suicide so the player should dodge its attacks, use ranged attacks and fireballs, and escape as quickly as possible.
