Worshipper – “Conquest” [Campaign 2, Mission 3]

GAZA SECTOR, what is the purpose of the demon army? The mission is designed to utilize the enemy's troops, meaning the elves, which can be hired in greater numbers from level 1 to 7. Gather reinforcements from two cities, and sooner or later, your army will become larger than Ilfina's. If you have logistics and she doesn't, you can try to lure her out of the city and capture her without a fight.

Did you kill the druids? If so, the elven troops will stop appearing, and no one will join Ilfina.
