Energy Mirror? I dunno.
Basically when cast on your party it reflects /2 the dmg into the minion with the most health in your party...
So in a 4 minion team:
M1: 5,000 life.
M2: 4,000 life
M3: 3,000 life
M4: 3,000 life
Minion 1 gets hit for 500 life, he only takes 250 dmg, the remaining 250 is then given to M2. M2 only takes 125 dmg, and the rest is given to M3, which takes 63 dmg, and the rest is given to M4. (if minions have same life it's given to whoever is closer to minion 1)
When cast it effects all of your minions, and dmg goes to all your minions as shown.
