Irradiated Slime

The Irradiated Slime is a Hardmode slime that only spawns during Tier 2 of the Acid Rain event. It has a very low chance to drop the Lead Core upon death, which provides immunity to the Irradiated debuff and is used in the crafting of Silva armor.

The Irradiated Slime is unique among slimes in that it uses Biome Mimic AI, allowing it to leap at the player.
