Hey guys, this is the idea I wanna pitch.
The dark spell would be called 'Evolve' : When dropped on troops or when troops run into it's area of effect, the troops instantly evolve to their next level. In other words, if a barbarian is level 5 and runs through the spell circle, it will evolve to level 6, it will stay in this state until the end of the attack. However, the spell will not work on troops who are already maxed out. As for the technicalities like how much DE it will cost, how many evolve levels each upgrade is worth and how long the spell circle lasts will be up to the programmers, should they decide to go with my idea
Feel free to criticise
