Paladin

Paladin is a rare Hardmode enemy who spawns in the Dungeon after Plantera is defeated in the same world. It throws hammers that can pass through walls. The Paladin also possesses the capability of randomly teleporting without effects to back it up in the event they get stuck. They walk very slowly, but no one should ever underestimate the power of their hammer. Paladins have a chance to drop the Paladin's Shield, Paladin's Hammer or Armor Polish. (Paladin's Shield and Paladin's Hammer cannot both drop from the same Paladin.)

They are immune to knockback and the Poisoned, Venom, and Confused debuffs, and only spawn in dungeons with a Brick Wall.

Tips

 * Be very careful when getting in its line of sight. It will not ordinarily throw its hammer at you if you are out of sight but it can be shown that it has the capability of doing so. It may also choose to throw its hammer if you jump while you are within melee range.
 * The Paladin has a bad habit of spamming hammers if the player is at a lower elevation than itself, be it one block or forty. Attempt to attack down at it, and don't fight it in hallways, as it leaves no room to dodge its hammers.
 * You can interrupt its attacks and prevent it from throwing its hammer just by constantly firing at it. Its normal melee is much weaker than its hammer throw, so you're better off taking a risk and running through it if necessary.

Trivia

 * The Paladin has the highest health of any ordinary enemy (excluding the Headless Horseman and Dungeon Guardian).
 * The Paladin may be a reference to Iron Knuckles from the Legend of Zelda: Ocarina of Time.
