I decided to revisit the good old Heroes of Might and Magic V and got stuck. Besides Ornell and Arantir, I only have 2 Necromancers from the tavern, and the tavern has been empty for a week now, so I can't perform the ritual and proceed to the Holy Flame. The Dungeon remains untouched because I was tempted by the trees with experience. I thought I needed to free that specific hero, but the walkthrough says "3 Necromancers from the tavern."
Are there any solutions besides restarting the game (what if it happens again???) and @Win()? :(
Just in case, my heroes haven't died; I only had to retreat with a secondary hero once, but he was immediately bought back. I don't remember seeing any Necromancers among the enemies, so I don't understand why this happened.
