Heart of the Night

No need to buff anything there; it's already intense, and people are complaining. We'll see what happens next. There are still many random parameters. Before the battle, I had a luck of 4 and a defense of 5, and I also got a random initiative boost. It requires a lot of replaying, it's a hassle. I just checked – I was fighting an Engineer in the Week of Retribution, and we were constantly under acceleration.
UPD: I won against Gilva. The main losses were due to Silanna's daughter wiping out her fairies and dancers. I got tired of resurrecting them, and the entire garrison was laughing at me, but without the fairies and dancers. I'll replay it. I saved the archers, druids, unicorns, dragons, and ents. The idea of summoning Exiles in the basement is actually quite good. It's especially useful when you're tired of everything at the end, and those ghosts take so long to hit... and there are only a few left in the squads, and then it's Exile-Exile-resurrect someone-Exile again. This back-and-forth certainly helps you progress. He attacked again, this time on Sunday evening, so I didn't get the weekly bonus. But I don't think it's critical. Let's see what happens next.

You need the ring for the quest, without which one Necromancer will be very unpleasant. The quest is given by the witch, the same one who offers skills to choose from.

So, these Necromancers are quite annoying for now.

Everything else can be obtained; the trident and dragon crown drop from the first level, but they're useless if you're not playing with machines on Chaos.

Of course, the crown and ring give +1 to everything.

I completed Gilva without any losses and resurrected everyone who suffered at the end. But it was so annoying that I forgot to save the replay. Maybe I'll replay it later with a beer if anyone is interested. The idea of taking unicorns with magic resistance is not a good one. Because someone will inevitably get poisoned, meaning you have to remove the poison en masse, so the resistance from the unicorns is useless. I separated the archers and druids into different areas. I placed unicorns with the druids and vampires opposite them, and they dealt with the vampires together; that was their task. They did it perfectly. The Child of Light is resurrected or regenerates well. And there will be plenty to resurrect. So, don't worry; if you also give the unicorn divine power, it will have a good attack. It's tedious, but there were no problems. At the end, when there are few enemies left, the Exile ability is like a balm for the soul – bam, and it's all over; the base is clear
