The Heal Stone is Snerlin's secondary special ability in Minion Warfare and Minion Warfare 2: Warmageddon. Upon being used, Snerlin summons a magical rock that regularly dispenses health orbs for its duration. Each orb dispensed will replenish around 25 HP, making it useful in a jam. It serves as a placeable source of healing for all Minions nearby its location, and will do so until it disappears after about 30 seconds.
