The Tesla Defibrillator is a Hardmode Healer spell that is dropped by Frankensteins during the Solar Eclipse event. It shoots a nearly instantaneous beam of electricity around 42 tiles long that heals the first ally it comes into contact with. The amount that is healed depends on the target ally's current health, with more badly hurt allies being healed more than less hurt ones.
