In my game. Even with Shettara and Nameless left there are still not enough Undead/Demons and I only have Reha left..very disappointing. I upgraded some Demon Artifiacts but that didn't bring Moro's % down...so wtf? lol How can you free they guy with so little Undead/Demons around?

don't forget to put black knights in castle before fighting with undead and demons~~~
(montero underground have about 5-10 demon creeps,verona may have 3-4)

in fact, splint of darkness isn't necesarry....the most advantage of black knight is easy to resurrect and if you want to get a high score, moro dark should die- - this poor guy has the 3rd exp(about 26k) in the whole game~

Are you saying you should not use BK's when fighting Demons and the undead?

YES

the formula of dark power may like this

enemy has undead -4
enemy has demon -3

your troop has undead +2(included backup)
your troop has undead +1(included backup)

Actually it's -5 for undead and -4 for demons, with +1 from undead in the army or reserve and +2 for demons in army or reserve. So in essence if an enemy army has demons and undead, the counter will drop down by 9. Pretty nice, but it is a rare occasion.

Well that's my game ruined lol I only started it to get the splinter. I didn't realise that when freeing Moro you don't use BK's (solo campaign) I could go back and do it all again....hmmm
