Ranger "Refugees" - [5th campaign, 1st mission]

Exactly, at high levels, after the first battle in a week, the energy runs out and that's it. In the fifth game, before patches 1.6 and 2.1, there were hordes of skeletons, and 15% of the fallen would turn into skeletons without any energy cost, and as a result, each battle would bring in hundreds of skeletons, and in the end, there would be a huge number of these skeletons.

Well, that's what I understood :)

Something is wrong with that damned Biaara. I've already opened the entire map, cleared all the neutrals, captured all the garrisons, no one is blocking her path, but she still doesn't move, she just stands there, oh, I wasted so much time for nothing, I'll have to replay it, but this time I'll play on Recruit difficulty, because if she doesn't come again, I don't need to waste so much time for nothing again)).
PS In general, I have all the Campaigns and all the missions unlocked, but in the next mission, my Faeiden is much worse leveled, so I will definitely restart.
PS The most annoying thing is that in the external guilds, I got almost all the dark magic spells of levels 1-3 :( and now it's not a fact that I'll be so lucky again
