Taborlin's Key

Once per game, up to 30 points of damage inflicted on the wearer can be negated. The damage must come from a single source, but the damage can be of any type other than Eldritch or Push.

Any unused damage absorption is wasted. E.g., if this charm is used to negate a 25-point attack, the 5 remaining points are wasted–they cannot be “banked” for later.
