Thread: cost reduce vs class evolve

Well im a fairly new player as well but, as far as I know for Cost reduction you need a copy of the same unit and feed the copy for it to work (and only the first copy has a 100% chance of working the next ones go lower in %) and Class Evolve (Or CC as players call it) is a must after reaching lvl 50 so the unit gains better stats and breaks lvl cap (ex a lvl 50 Katie after CC goes back to lvl1 but retains her stats and can grown to lvl60) but the cost of the unit goes higher

Forgot to mention that after CC some units change the skill (katie goes from 10UP to 15UP after CC)
