Discussion about the Stronghold faction.

The only thing I haven't quite figured out is "Strength vs. Magic." Sometimes it works so that when I cast it on the Weavers, their Tower moves, and they spend the entire duel fighting only in melee, and for some reason, in spider form. It's actually nice because in human form, they are stronger, and their Deadly Gaze works.
Strength vs. Magic also works normally on Sanctuary.
And now I just beat the Necropolis. In the first turn, I cast Strength vs. Magic, but the Weavers immediately started shooting, and they did a lot of damage to the Centaurs, although it didn't help them.
Maybe they dispelled it? I didn't look at the combat log. I'll look next time.

Chingiz, you haven't figured out Strength vs. Magic, but rather the Centaurs! When they move, they take two turns: one for shooting and one for moving. So, if you cast Strength vs. Magic on a Centaur and then have them shoot, the effect on them will end at that point. The same thing happens if one of your units has Battle Fury and you move them after that. I fell for this myself at first: it seems like I've protected everyone from magic, and then I see that someone is getting hit hard by that same magic. :) You just need to be more careful. When I fight the Undead, I often have the Centaurs skip their turn just so everyone is protected. The same goes for Battle Fury – I just defend with everyone. You just need to carefully monitor who has Strength vs. Magic applied and for how many turns, taking into account the Centaurs and Battle Fury.

As for the fact that the spiderlings fight in human form for the entire duel, that's just the AI being bad. It always fights like that if they are blocked. And if they can shoot, then they only transform and shoot. It's just a noob. :)
