Flying units in Heroes 2.

Then who would we use in battles? IMO, these are the most important units at the beginning of the game. After all, building Titans requires a huge amount of money and gems. And before Titans appear, Rukh become one of the main stacks... Or am I missing something?

Well, yes, I did take a rather specific situation. The difficulty is hard, but not impossible, there are plenty of resources, the mines are not guarded by very strong monsters, and there may be hidden spots with neutral creatures. That is, when there is an opportunity to build giants in the first week, there may not be enough, say, 3000 gold.

And, by the way, a small correction, there was a typo in the post - not crystals are needed for Titans, but pearls.
