Aethusa's Prison

Stealth +32

Disable DC 42 nature (legendary) or DC 45 crafting (master) to remove an immunity the prison currently has to one of the following damage types: acid, cold, electricity, or fire (this effect lasts until the prison uses its Energy Immunity reaction to regain that immunity); DC 42 arcana (master) to fortify the pedestal's containment runes, preventing the prison from using its Chromatic Eruption action for 1 round and causing it to suffer feedback that inflicts 20 untyped damage (this damage bypasses the prison's hardness and immunities); DC 42 thievery (master) or Dispel Magic (8th rank; counteract DC 34) to suppress the pedestal's containment runes for 1 round, preventing the prison from using its Self-Repair action and causing it to suffer feedback that inflicts 20 untyped damage (this damage bypasses the prison's hardness and immunities). Unlike most hazards, Aethusa's prison can't be disabled, but it can be destroyed by reducing it to 0 Hit Points.
