New RPG map for Heroes 3.

I played through the map )) but quickly ))

Ideally, the map was created for this purpose, and not to make players spend months of real time on it.

There is no clear hint about the Air Dean.

Well, not everything should be too easy.
Hints:
- it doesn't block the passage
- fresh forces -> rest -> restoring movement points - why?
- this is the Faculty of Air, and they have a different approach. Remember at least their first test, where you had to run, and the battle itself was easy.
Although, perhaps these hints should be given in plain text.

quest to return the troglodyte

This is a joke - imagine the guy who gives this quest,
go to him without a troglodyte.

In general, it makes sense to read what many quest givers (huts and border guards) say if you visit them a second time before completing the quest.

I highly recommend removing Pathfinder from the hero's skills.

I'll think about it, but in this case, the hero might become too powerful. And secondary heroes really don't need this skill, so I'll probably remove the event.

where can I get 1 sulfur (plus the one given by the dragon zoo)

This is an alternative to the early stages of the game. You spend sulfur either on the alchemist (for increasing strength), or on the dragon, or on the laboratory golem (border guard).

I only found 18 hobbits out of 19 for the quest... where is the last one???

He is on an event, next to the overseer. The problem is that this gives access to free creatures, i.e., it is either for those who cannot pass otherwise, or for those who want to complete the entire map with all branches.
By the way, the lizard is also on an event, next to the hobbit you already found. However, this event is not entirely positive.

Water Dean, 1 dragon

If a second campaign map is created, then the dragon and the mage will have different paths; they simply won't let you into the dragon's city.
