Paladins are rare, resilient Hardmodeenemies 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.
Although Paladins have a visual height of 4 tiles, they can pass through 3 tile-tall corridors.
Paladins cannot throw hammers while moving.
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, immunity to knockback and high defense, making it difficult to kill and dangerous to try to slip past or ignore.
Paladins are less likely to target players outside their line-of-sight, or players at higher elevations (it generally cannot fire above 45 degrees). Attack from directly above it: This avoids the hammer attack entirely, and the Paladin will remain directly below the target player.
Fighting it in hallways is not recommended, as this leaves no room for dodging, and often leads to a quick death.
A Paladin's attack will be interrupted if it takes damage, making fast weapons more effective at keeping it suppressed.
The damage taken from touching a Paladin is much weaker than its thrown hammers.
