Red Devil

The Red Devil is a Hardmode enemy that spawns in The Underworld after any mechanical boss has been defeated. It is considered a more difficult version of the Demon, having more health and dealing much more damage. Similar to a Demon, it drops a magic weapon resembling its mean of attack, the Unholy Trident.

While the contact damage of a Red Devil is comparably low, its trident attack is capable of dealing large amounts of damage even to players wearing endgame armor. The tridents are fired in the same burst-like pattern that Demons fire scythes in, although they are slower and move at a constant velocity.

Tips

 * Due to their relatively low knockback resistance, they can be easily stun-locked with rapid-fire weapons, such as Megashark or Chain Gun. That still allows them to fire tridents, however.
