Heartbond
Faction2 / 4 / 6 / 10Heartbond Heroes can bond in pairs when deployed. Bonded Heroes enter Dormancy (invincible and unable to act) when HP drops below 1. If their partner is still alive, they reawaken with 60% HP. The Dormancy duration increases each time: 3s (1st), 3s (2nd), 5s (3rd+). Tap a Heartbond Hero and drag the Heart button to another Heartbond Hero to form a bond. Dragging a bonded Hero to the Hero Slots breaks the bond.
