Terrarian from Best Melee Weapon Terraria
Weapons of Terraria can vary greatly. Like, a LOT. This one is a yo-yo from the Hard mode that drops from the Moon Lord boss 11.11% of the time. Despite being a yo-yo, it can inflict very high DPS, which compensates for base damage. 190 melee damage and 14% critical chance make the entire thing that much sweeter.
