- Regen Wand: A regen wand is a tubular device roughly fifteen inches long. It emits waves of energy that promote cellular growth and healing. The device is standard issue for most first aid kits and is simple to use. It is exhausted after a single use. System: A single regen wand can restore all Bruised or Lethal damage in the Bruised, Hurt, or Injured boxes. Anything more is beyond its capabilities.
