Evolutions

I just now finally managed to get a second copy of a lord, previously all i ever saw was gold. So i evolved my void to A+, my question is this. Is it possible to evolve my A+ void again by getting another void? or would it require 2 voids to makea second A+ to evolve my first A+, or are evolutions capped at a one time thing?

Just trying to get a feel for if its worth farming more of the same or if i should just evolve all my team to A+, granted Blood Blush Vanessa makes that a bit more difficult.

If u put them together and the button will not change to evolution... hence nope. There is nothing past A+ there is no S or such mythical rank as of yet.

Thanks kind of figured that was the case, but since it took so long to get a second one just to get my first A+ figured id ask before spending all that energy to get another to see it for myself.

I had 4 leveled Void+ at one point... got kinda boring

sorry the question but to evolve a monster from B + to A , I can sacrifice any monster A or I do like the monsters A which are 2 equal ?
