Walkthroughs for custom maps.

Nasos, yes, I didn't go into more detail – there are already a lot of words (by the way, thank you for reading it :)).
32767 = 2^15-1. Adding 1, we get 1 in the highest bit, which will be interpreted as a minus for 16-bit signed numbers.
In the last battle, in the last best attempt, I took 39764 skeleton warriors, BUT in the save they are divided, and after saving, another heroine gives 7000 skeletons, and Erdian attacks Lea de Vuz. Overflow does not occur during normal actions, but when reading the save or changing turns, you may get a negative number, so you need to remember this and take precautions. Here, in principle, 32 thousand skeletons are enough, it’s just that the more there are, the easier it is to win.

overall walkthrough of 2000+ (!!!) MONTHS.

And I naively thought that 20-30 months was too long! :D Now many people are creating maps for HotA, and there are often Giant-sized maps – I think this is for hardcore players: in the same time that you complete one such map, you can complete a dozen XL maps. :) Besides, the authors also prohibit the use of City Portal, Flight, and Dimension Door.
