Weapons

Weapons are essential items used for combat against enemies, bosses, and even other players during PvP games. They typically deal more damage than their tool counterparts. Some weapons can be crafted at a Work Bench or a Pre-Hardmode/Hardmode Anvil, while others can only be found in Chests, as enemy drops, or purchased from NPCs. Terraria has a wide variety of weapons and weapons classes, each suited to particular play styles or specific tasks.
