I finally found the ending of the game.
I shall spend another few hours to get to that point and use 2 - 3 thousand souls in a single army.
Games amazing and I also recommend maybe adding a level type that doesn't have bomb enemies. They keep you from advancing pretty effectively but also kills a ton of their teammates. Maybe a artillery type unit could be the alternative support, long range, low damage, decent rate of fire. The mage guys are already heavy gunners but with how they attack, they are typically seperated from the group and when I have a larger army, the mages typically just get dismantled before they really do anything. Not that the mages arent cool and aren't strong. when they first appeared they felt like absolute monsters and I died not long after.
