kolotok, is this all based on the Polish version?
Generally, I prefer to honor the capture rights of Jiuply and leave Cypsela alone. Because capturing that useless village doesn't give you anything except a small increase in gold. At the same time, losses are inevitable, but more importantly, Cypsela loses part of her army there.
Waiting a couple of weeks for growth is a normal strategy and doesn't ruin the walkthrough. You can still reach Inferno; it arrives at the 4th village around day 431, and you can intercept it there (that's what I did before the patch where the blue garrison attacked on day 311). This is a normal timing.
In my current walkthrough, I'm using Lucifers and Pitambars and reaching 341, but this is a rather high-quality walkthrough that, while reproducible, will require a certain level of skill from you.
What is your timing for building the snakes, bulls, vivs, and Capitol? And have you lost more than 6 gnolls in any battle? Except for the battle with the dragonflies on the respawn point, losses can definitely be reduced. In each battle, you should only lose gnolls and as few as possible.
Regarding enemies, only Cypsela, in her first appearance, inflicted losses – but significant ones, around 80 gnolls. And this is already with her army reduced due to capturing the rights of Jiuply.
