Heart of the Night

I equipped artifacts on the Imps. This gave a +25% bonus. As a result, my troops have an initiative of 17, while theirs is 75. Also, look at the stats of the Imps - 80 health, 75 attack. Archdevils have 2000 health and 110 attack. I really don't understand what the problem is because in the walkthrough for the remake, Baal was a regular enemy.
