The following spells are NOT allowed to be used with one another, or by itself just to inform you all. In the next update it should be fixed, but for now you are not allowed to use any of these combos.
Pericing + Stop is not allowed.
Zombie + Revive any level is not allowed.
Death is not allowed.
Vigor is not allowed. NOTE: Will be allowed in next update.
Light 4 is not allowed, due to double attacking glitches.
More MAY be added later, but for now this is the offical list so far.
