Red Devil

The Red Devil is a hardmode enemy that spawns in The Underworld after any of The Destroyer, The Twins, or Skeletron Prime has been defeated. It can be considered a harder version of the Demon.

While the Red Devil itself does not cause much contact damage, its trident attack is capable of dealing large amounts of damage even to players in Hallowed armor, Chlorophyte armor and Turtle armor. The tridents are similar to the Demon's scythe attack, but do more damage and do not accelerate.

The Red Devil is immune to the On Fire! debuff.

Tips

 * To defeat it, attack only while it charges his tridents. While he shoots, focus on dodging only, as receiving more than 4 hits will probably kill you.

Trivia

 * The Red Devil may be a subtle reference to VMFA-232, a US Marine fighter attack squadron nicknamed the Red Devils, as their emblem looks very similar to the appearance of this devil in-game.
 * The Red Devil may be also be a reference to the Red Devils of the NES title Ghosts and Goblins, who are also notorious for being extremely hard to kill for less experienced players, and both appear to look quite similar.
 * The Red Devil may also be a reference to Manchester United's crest, with the spear, but no wings.
