Heart of the Night

you can do without a mine; the upper garrison of the city serves as a mine; the main thing is to fill all the cells at the bottom (and make sure there isn't a single type of creature at the top that exists at the bottom) - I used this when I failed to defeat the first Necromancer; it works. It doesn't work if you need to capture not all the sprites, but specifically 1-4, but then the option of changing their upgrade doesn't work for me; I always need sprites anyway)) (although my blue sprites are very enhanced by a mod, the yellow ones not so much :)

Otherwise, the map is excellent; adding Necromancers would definitely not be superfluous, although after the tactics, you need time to recover; two weeks later for the next one is too soon.
