The Irradiated Slime is a Hardmode slime that only spawns during Tier 2 of the Acid Rain event. Rather than spawning like normal NPCs, they gradually fall from the sky while the event is ongoing, and can fall through platforms while doing so until they are at a similar height to the player. 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.
