The Ultimus Cleaver is a Hardmode broadsword that drops from the Ravager. When swung, five homing gravity-affected sparks will fly out of the weapon, with each one piercing up to 4 times and dealing one-tenth of the initial damage of the Cleaver. The five sparks are always thrown out at the same semi-equidistant angles, with the highest going straight upward and the lowest going straight forward, regardless of where the player is aiming. Each spark lasts for 2 seconds before dissipating. Additionally, landing a true melee hit will cause explosions to erupt on the target, dealing additional damage.

Its best modifier is Legendary.


  • The explosion generated by sword hits deals exactly 100% of the weapon's base damage, can not critically strike, does not damage nearby targets, and cannot be modified by any means.
    • This effect, along with its visuals, is identical to the Hellkite.


  • When it was initially released, and for a few versions thereafter, the weapon was not actually swung, and instead was held out as it was used, with sparks flying out only when the user was on the ground.
