Well, after many tries I could beat the all the battle with flawless victory without using either quick save nor resetting turn, I could even kill all the soldier in the battle where you have to survive 10 turns.
It was a nice challenge, I loved the game, it was quite hard, mostly in the fight against the Voronese Army, the grenadiers were problematic to deal. doing a lot of area damage. It got easier after the second playthough, since I started abusing the Mockery skill, setting some sort of meatgrinder.
Now is time to wait for the next chapter, keep the good work!.
