Disciples 2 legions conquer empire capital

the game is disciples 2 rise of the elves; quest "nyullokth's vengeance" using legions of the damned. started with imported warrior leader at lv6 with incubus horn equipped. the guardians of the capital are overpowered, the only way to kill them is using paralyze or petrify (at least i think), and of course survive their first attack XD... i've used a fortune potion(permanent hit+) on incubus(what a sweet demon :P) and a invulnerability potion(-50% dmg) before battle to survive myzrael attack, and some strenght potion to speed up a little the process. after beating him u get everything the race had, for some reason i didn't get their spells. well w/e enjoy :P
