Antiseptic (5 uses)

Once applied, this fresh-smelling cream can keep a wound moist and prevent infection for more effective healing. You can apply an antiseptic as an action. 
When a non-synthetic creature treated with an antiseptic takes a short rest, they roll a bonus hit die and add the result to the total number of hit points regained from the rest. Once a creature benefits from an antiseptic, it cannot do so again until it finishes a long rest.
