Irradiated is a debuff with different effects depending on what it has inflicted. If inflicted on the player, they receive various stat increases and decreases. The Lead Core accessory, dropped by Irradiated Slimes and Gamma Slimes, provides immunity to this debuff. If inflicted on an enemy, their health decreases over time. All enemies immune to either Poisoned or Crush Depth are also immune to Irradiated.

    • Notes[]

    • While the player has the Old Duke's Lore item in their inventory, the Irradiated debuff increases their defense and damage reduction instead of decreasing it.

    Trivia[]

    • Irradiated's name was reverted after being previously known as Acid Rain, which was a debuff inflicted on the player during the Acid Rain event.
