Case Resonator is an augment. When obtained, it enhances the effects granted by any core augment in the body slot. If the player does not have a core in their body slot, the augment does nothing until they obtain one.

It can be found as a drop from Gold Chests. It can also be found in Shops with a price of 35 Nuts.


  • With Armatort's Shell, if the player takes damage when they have armor, there is a 50% chance for the player to take no damage at all.
  • With Owlhawk's Reign and Dracopent's Pride, whenever the effect triggers, the amount of health restored is doubled.
  • With Oxjack's Guile, the shield will retaliate with a spread of five bullets if it blocks a projectile.


  • Case Resonator was introduced in the 1.3 Update to 20XX.
