Paladin

Paladins are rare, resilient Hardmode enemies that spawn in the Dungeon after Plantera is defeated. They throw hammer projectiles rapidly that can pass through blocks and inflict extreme damage. Paladins only spawn in Dungeon areas with Brick Walls.

Paladins are immune to knockback, as well as the Poisoned, Venom, and Confused debuffs.

Tips

 * Paladins are exceptionally tough enemies. Their projectile attack is unusually versatile for a non-boss enemy and inflicts extreme damage. A Paladin has more health than Skeletron, and combined with its immunity to knockback, makes it difficult to kill or avoid.
 * The Paladin is less likely to target players outside its line-of-sight, or players at higher elevations. Attack from directly above it.
 * Don't fight it in hallways, as this leaves no room for dodging, and often leads to a quick death.
 * You can interrupt its attacks and prevent it from throwing its hammer by constantly firing at it.
 * Its melee attack is much weaker than its hammer throw, so you're better off taking a risk and running through if necessary.

Trivia

 * The Paladin has the highest health of any ordinary enemy (excluding the Headless Horseman and Dungeon Guardian).
