I would consider the possibility of freeing Boragus and Gretchin with a berserker, azure dragons, and rusty dragons as a conditional disadvantage, unlike Marlo, because they need to be freed quite early, and the enemy is not idle and also wants to do it. However, the difficulty also lies in the fact that there is an event with very strong guards at the beginning of the 3rd month before the prisons, which is almost impossible to break through with the same Craig due to the simple lack of mana. So, I would definitely not call it a freebie.
I started breaking through the 3 main bosses with Gundula; I also chose the landscape for her, but not the one he chose. I managed to find a place with access only for 1 hex unit, and then everything is simple.
I managed to conduct the battle with Mephala on the castle defense in such a way that she did not teleport the golems until I squeezed all the mana out of her to 0. I noticed a pattern when she threw the golems and when she didn't, and the battle was won based on this.
It is also interesting how it was possible to kill 7000 Xerxes' ifrits. In general, the result is good; if I hadn't used quick spells at all, I think I would have finished the walkthrough somewhere around the 6th month.
Has anyone tried to investigate the question of when the computer will split its ranged unit stack?
