Round table

The gargoyles started rushing. But it's not about them, it's about the fact that there was no wagon.

Well, without a wagon, you definitely won't win. But 2 level 5 gargoyles + a wagon is excellent cover. Pixies are only good for distraction. In general, the recipe is simple: wait for daytime, build a forge, buy gargoyles, and easily defeat these dwarves.
