This is a team healing spell. No attack by your hero will happen for the round. Instead you will heal your team based on the formula provided. Amount healed = (Intelligence of hero + hero's level) (power of card + card level) / 10. Card power for blue = 7.5; purple = 10; yellow = 12.5; red = 15. Example: hero is lvl 35 with 100 intelligence and has a level 4 blue Druid Blessing skill. Amount healed = (100 + 35) (7.5 + 4) / 10 = 155.
