The Hide of Astrum Deus is a Hardmode accessory that drops from Astrum Deus. The wearer creates an astral infection explosion and twelve astral stars rain from the sky that damage nearby enemies upon being struck or dealing a true melee hit. True melee damage is boosted by 50% for up to fifteen seconds after being struck by an enemy. The Hide of Astrum Deus also provides immunity to Astral Infection, Cursed Inferno, On Fire!, and the Frostburn debuffs. Any enemy that hits you will take 75% of the damage they dealt.


  • This accessory synergizes well with the Blood Pact, as getting struck by a critical hit makes the true melee boost longer.
