Reminiscent of a collection of sawbones’ syringes, this apparatus administers an elixir of the of the wearer's choice after sustaining an injury. 

When your hit points are equal to or less than half your maximum you consume the potion contained within with no action required as if you had spent an action to do so.

Once the potion within has been consumed it must be replaced. It takes 1 minute to fill or decant the potion contained within the Auto-Injector.
