Incubation

[Morrigan]

I understand that keeping the protection even is important... start with Exo hero then Endo... However, I heard there was a way to force a certain outcome and I haven't figured out how to do it.  Which combinations give what outcome? Bela and Hela for example can be combined with Summoner, Warrior, HP, etc.

What is the best to choose for what situation?  I will be experimenting and will post here.  Help and input is much needed and appreciated.
