First Wave Build Auras and EV beams
Second Wave Build as much minions as possible try to get at least a few archers on each Buff beam
Note: After First wave try to stay around Archer minions at hint 3 so as not to aggro Ogres to south west or north west Cores. I basically would just roam from top right core to bottom right core and upgrade before bosses.
Note: Place the Archer at hint 4 Sometimes later in the waves Its unnecsary for earlier but I lost to a spider who somehow managed to reach my crystal a few times.
Note: I used Jester during boss wave so I could use my wheel to heal all defenses well standing behind / on top of my mage minions
Note: If using strategy above beware stepping to far to the right as the helicopters will occasionally reach you and the splash damage will hurt pretty badly.
Note: The Bosses solo have 500mil x 4 and 1bil x 4 health it takes a while good luck.
