Hey guys I'm stuck at chapter 18 of Conquest, the fact that all the enemies are promoted and the only ones on my team are me and the royal family barring the smallest one. Should I start promoting my units now even though their not maxed out yet? Zero is 18, Keaton 17, Effie 17, and Silas 14. Which ones would it be good to promote now and anybody have a solid strat for this chapter I have to take down Zola and two generals within 20 turns and my only good magic dealing units are Leo, me and Nyx (not really shes 11 lv wise)
