Terraria Overhaul/Slime Gun

The Slime Gun is a weapon that is purely novelty in Vanilla, but has a combat purpose with Overhaul installed. It auto-fires an arc of slime that inflicts the Slime Debuff on players, enemies, and NPCs, causing them to drip blue goo for 30 seconds, and also increases damage they receive from the On Fire! debuff. The Slime Gun can be used limitlessly and does not consume any ammunition or mana. It has a 2/3 (66%) chance of being dropped by King Slime.

The Slime Gun cannot be reforged, and therefore cannot have Modifiers.

Fire Damage Bonus
All players and enemies with the Slime debuff now receive x5 damage from the On Fire! debuff, which makes it extremely useful in Pre-Hardmode.

Slime Explosions
