The Slag Magnum is a Hardmode gun that is dropped by Earth Elementals. When Musket Balls are used as ammo, it fires a special bullet that inflicts the Armor Crunch debuff on targets for a short time, which reduces their defense by 15, and splits into 4 small shards on impact which deal 35% of the original bullet's damage.
Its best modifier is Unreal.
- Because of the high armor reduction, it is much more effective on enemies with high defense. This means it can be quite potent as a support weapon throughout the entire rest of the game.
- Due to how early it is available and its powerful effect, it is an excellent weapon against the Mechanical Bosses.
- Its effect is very similar to Crystal Bullets, making it an excellent crowd control tool.
