I'm not a sage in this game at all, I play for fun mostly and I constantly have to watch my unit losses but yesterday I was trying to get scrap units for sacrifice and used up the eggs I had saved and got 2000 of those flying, red mosquito things and went into a battle so I can sacrifice them for some demonologists and I actually used them to hit a unit of Orcs and did 74,321 damage to be exact. It was funny as hell because I didn't expect much from them. Too bad they die so easily in battle..I have the Whip and the poison Dagger so that helped alot with the damage.
I also used up alot of the spider eggs I had with some artifact I got from killing Moro Dark which gives spiders alot of power and was cleaning house with them too.
Freaking addicting game!
