Paladin

The 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 his hammer. Paladins have a chance to drop the Paladin's Shield, Paladin's Hammer or Armor Polish.

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

Tips

 * Be very careful when getting in his line of sight. He will not ordinarily throw his hammer at you if you are out of sight but it can be shown that he has the capability of doing so. He may also choose to throw his 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 him, be it one block or forty. Attempt to attack down at him, and don't fight him in hallways, as it leaves no room to dodge his hammers.
 * 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.
 * Scourge of the Corruptor for melee oriented players is highly recommended, as the constant barrage of little eaters will always interrupt his attacks. This can be found in Corruption Chests.
 * 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 do not 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.
 * If you have the Shadowbeam Staff, you can stay out of his sight and attack him indirectly by bouncing the beam on walls.
 * Using Shroomite armor will result in the Paladin constantly throwing its hammer at you, even in melee range.
 * Standing above him and using a Nimbus Rod, you no longer have to worry about the hammers. you DO have to worry about him moving out of place and tossing a hammer while you attempt to deal with other enemies.    It's highly suggested to use Spectre armor for this situation.
 * You can use a "hit and run" strategy using Magnet Sphere and highly suggested, Spectre armor. This will cause you to be out of range for his hammers and heal you up in case you take damage from a few of them while using the Sphere
 * If you were lucky enough to find the Piranha Gun, you can nearly stun lock the paladin and deal damage from out of range of his hammer throws. This is best achieved by locking the piranha on the paladin and then flying a full screen above him.
 * The Jack 'O Lantern Launcher is a very efficient weapon against him.
 * The Paladin Hammer is a very good weapon against him.

Trivia

 * The Paladin has the highest health of any non-boss enemy. Prior to 1.2, Wyverns held this title, with 4000 health. (Arch Wyverns have 8000 health, but those are exclusive to the console version.)
 * Because of its extremely high health, damage, and rapid-fire attacks, it is often considered the most difficult non-boss enemy in the game.


 * Like most rare dungeon monsters, one of the Paladin's drops is a weapon that functions similarly to his own attacks.


 * Paladin is likely named after Dan Paladin, a programer and one of the founders of The Behemoth. Paladin in Terraria is a knight, this is likely making a reference to Castle Crashers, a game by The Behemoth.
