The Paladin's Hammer in action.

The Paladin's Hammer is a Hardmode, post-Plantera boomerang that has a 1/15 (6.67%) / 29/225 (12.89%) chance of being dropped by Paladins in the post-Plantera Dungeon. The projectile can pierce infinite enemies but cannot pass through blocks.

Its best modifier is Godly or Demonic. Both modifiers increase the average damage output by the same amount. However, Ruthless might be preferred if the player already has very high critical strike chance.

Notes

Similarly to most boomerangs, the Paladin's Hammer receives increased velocity and range from melee speed bonuses, but not attack speed.
While the hammer is clearly visible in darkness, it emits no light.

Tips

The infinite piercing of the Paladin's Hammer makes it very effective against segmented enemies, which it can strike multiple times in one pass.
The Paladin's Hammer has similar DPS compared to the Possessed Hatchet; however, the former pierces infinitely, has a higher velocity, does not home in on enemies, and has much more knockback.

Trivia

A second Paladin's Hammer can be thrown before the first hammer returns with precise timing.

The hammer is a common choice of weapon for paladins in many fantasy games, though they are not often thrown.
The hammer's throwing function is similar to Mjölnir, the magical hammer wielded by the Norse god Thor, which would return to his hand after being thrown.
This is the only hammer in the game that has no function as a tool, but still activates the "Stop! Hammer Time!" achievement.
Unlike the projectile thrown by the Paladin, this weapon cannot pass through blocks.
