Calamity Mod Wiki

Several items in the Calamity Mod can prevent death if the player takes fatal damage while they are equipped. The player is revived back to a certain amount of health, or prevented from dying via other means, and is usually granted additional effects.

  • Player is unable to die and immune to most debuffs for 8 seconds.


  • The revives have an order of priority in which they get triggered: Nebulous Core is always triggered first, Silva is triggered only if the former did not and then, Permafrost's Concoction is triggered only if the other options did not.
  • Prior to 1.5, the God Slayer armor had a revive similar to the Nebulous Core, and all variants of the Auric Tesla armor had Silva armor's revive.
  • Armageddon's instant death effect bypasses all revives.
