Auto-inject Healthpak

A prized example of Consortium medical technology. A creature may have only one of these equipped at a time. This item takes 2 actions to attach to one's body.

Once attached, a creature will regain 4d4 + 4 hit points automatically when its hit points drop to half. The injection is not without side effects, as it speeds up the creature's metabolism in order to heal it. 

After using 2 Auto-inject healthpaks in one day, a creature must roll a DC 14 CON saving throw or take a level of exhaustion. The saving throw DC increases by 2 for each Healthpak used above two.

Notes: Bonus: Hit Points, Healing, Consumable
