+Unlike other forms of healing, the heals ability will not take effect on the healed unit’s turn, but on the healer’s turn. This means that while a unit surrounded by several healers on the same side will only receive healing from one healer per turn, a unit surrounded by healers from several allied sides will be healed once on each of said allied sides’ turns."
