Pathfinder: The New Age of Haven
Gem, 10 points of energy damage negated once per day.
The first time someone carrying the Energy Heart takes acid, cold, electricity, or fire damage, the gem reduces the amount by 10 (to a minimum of 0).
The gem’s power will be recharged by the next day.
This gem was found in a room in the lair of a Black Dragon Whelp, located on a pedestal between two statues in a room with a fiendish trap.
The Party solved the puzzle and after checking for danger removed the gem from its resting place, giving it to Charlotte.
