Ophidian

Ophidians are monsters from Heretic that resemble snakes and carry pointed staffs. When attacking, they fire a chain of three purple shots from their staff, pause, and then fire a red fireball. Ophidians sometimes drop a Flame Orb when killed. These particular Flame Orbs are worth 5 shots instead of the usual 1 shot. The Ophidian stops firing briefly between the purple shots and the fireball. The purple shots do up to 8 points of damage and the fireball up to 24 points. Ophidians are considers as tough as a revenant from Doom.

Some source ports refer to the Ophidian as "Snake" or "Serpent".

They first appear in The Storehouse.
