Stan

Stan is a Hard Mode miniboss encountered in the Underworld that has a 20% chance of spawning upon defeating at least 10 Demons and/or Red Devils within 20 minutes.

He looks like a very buff demon with wings that look too small for his body and is about the size of the Paladin. He can only move by walking, jumping and gliding. He is surprisingly nimble and also very fast. He attacks with Stan's Blade, he will only attack when the player is within range.

When he reaches half of his health his wings grow to match his body size, he is able to fly, his melee attacks get stronger and he shoots Demon Arrows from between his horns.

When he reaches a quarter of his original health he will summon 3 Red Devils to assist him in battle, he can will be able to shoot tridents similar to those of Red Devils and his attack rate also increases.
