P.S. Actually, everything needs to be fixed.
In the real game, I couldn't find anything better than trying to level Gunnar's Tactics on Genies, then kill the Snipers, take the Wood, and then use Crag to bust the external dwelling and max out the Dwarf Cottage. But Gunnar, by level 3, had leveled up Logistics to Expert). And the Genies had a huge stack of 5, and they took down 2 of my birds with morale.
So the question is: what is the earliest day this external dwelling can be taken, playing from day one.
If you can't be bothered, you don't have to upload the saves; just tell me what the build order is, what troops you have, and what level the hero is. And of course, what the losses were. For simplicity, you can assume money is no issue, although in reality that's not the case, but there isn't enough for Behemoths; everything else can be built.
2nd question (arose after looking at the leader's save): how, in general, should one have optimally developed on this map. One of the starting heroes is Gunnar.
