King Slime might not rule over much, but they’re royalty nonetheless, as they’re the first boss most players encounter in Terraria and the one most likely to squash you when you least expect it. Big, blue, and bouncy, this gelatinous monarch is the perfect entry point for testing your mettle, dropping some handy loot and setting the tone for boss battles to come.
Unlike the more dramatic foes lurking deeper in Terraria’s layers, King Slime is pretty casual about the way in which it appears, showing up if you poke it the right way or sometimes just crashing the party on its own. Although entirely optional, defeating it is often the first step towards serious progression, unlocking early mobility options and giving newer players a clear combat checkpoint. Here’s how to summon and beat King Slime in Terraria.
