Queen – “The King’s Sunset” [Campaign 1, Mission 5]

It's unclear where the berserker came from. In the garrison, there are 1000 high-initiative demons. They moved first, and Isabel only had the "Pray" spell left (which doesn't require mana). But I had 850 archers and 16 archangels.

There's a ring on the map that gives +1 to base stats and +10% initiative to archers. A ring that gives +20% initiative to all units can be bought. So, it turns out that inquisitors can definitely move before the demons (as well as archangels and paladins) and destroy the entire stack with one shot. At least, my demons didn't get a chance to move...
