Every Terraria prefix — 97 reforge modifiers that tune a weapon or accessory's stats at the Goblin Tinkerer.
On weapons, Legendary (melee) and Godly or Demonic (others) maximise damage. On accessories, Menacing gives the most DPS and Warding the most defense.
Prefixes, or modifiers, are reforge stats attached to a weapon or accessory. Visit the Goblin Tinkerer to reforge and reroll them.
