- A reference guide and manual in Russian for Heroes 3.

Yes, I agree that it may take a lot of time and luck :)
Regarding the resulting damage, do you mean the two possible scenarios:
- base damage (RND=20) + luck (RND=20) + double damage (RND=20) = 60;
- (base damage (20) + luck (20))*2 (double damage) = 80.
Therefore, in the second case, the damage will always be even.
:D It seems like a small detail, but it's interesting to get to the bottom of it:D
