Cluster Spell
What the spell does is clusters all your troops to follow that specific troop. What ever path that troop chooses is where all the troops go. If the troop dies the spell dies, to help keep that specific troop alive you get a small% increase in health
To use it just click the spell, then the next troop you drop is the cluster leader ( wont work on ClanCastle )
