Paladin

The Paladin is a Hardmode enemy who spawns in the Dungeon and throws hammers that go through walls. He can drop the Paladin's Shield, Paladin's Hammer or Armor Polish. The Paladin also possesses the capability of randomly teleporting without effects to back it up in the event it gets stuck. He walks very slowly, but no one should ever underestimate the power of his hammer.

They are immune to the Poisoned and Venom debuffs.

Tips

 * Be very careful when getting in his line of sight. He won't ordinarily throw his hammer at you if you're out of sight but it can be shown that he has the capability of doing so.
 * You can interrupt his attacks and prevent him throwing his hammer just by constantly firing at him. His normal melee is much weaker than his hammer throw, so it's better off taking a risk and running through him if necessary.
 * The Chlorophyte Partisan can handle him from behind walls thanks to the smoke it emits right as it starts retracting. Use this to easily defeat him, but you'll have to constantly punish him. Keep your guard up for Necromancers as no doubt you may get swarmed if you don't pay attention.
 * The Death Sickle is highly effective at defeating a Paladin in under a minute thanks to high DPS and DOT, and the fact you can hit him on the other side of a wall/floor/ceiling.
