Heartbond
Faction2 / 4 / 6 / 10Deploy a Heartbond Hero on another Heartbond Hero's special tile to bond them together. When one of the two is about to die, that Hero will enter dormancy. If their bonded Hero is still alive, the dormant Hero will reawaken with a certain amount of HP and rejoin the battle. The dormancy lasts for 3s the first time, 5s the second, and 5s the third and subsequent times. Placing bonded Heroes in the Hero Slots removes the bond.
