Stuck in the "Tales of Destiny" map (Heroes IV)

[Mamamia]

I started playing the "Tales of Destiny" XL map but I quickly got stuck after reaching the first Dream Teacher.
At that stage, there are thousands of bandits blocking the mountaing pass to the West. The hero Mira says that she knows of a detour to slip unnoticed but I was unable to find it. The only other way to make process is to head towards the green portal but it is being guarded by a stack of 12 efreeti and 5 goblin knights which are impossible to defeat whith a weak hero and one demon.
Am I missing something?

The green portal is the path you should use,but the battle should be much easier.On what dificulty are you playing?Try restarting the map,so the monsters would change.

Have you already rescued Nathaniel from his prison? If so, you can go through a quest gate to a yellow portal to the next part of the map.

Yellow portal is after that.You need to go through the green portal in order to have nathaniel.

I was playing at the Advanced level. I restarted the map at the same difficulty level, and by 4 day I was starting the battle with the creatures guarding the green portal. This time, I had to fight 11 nagas and 7 genies, and again, the fight was impossible to win.
I then restarted the map at the Intermediate level and won that fight easily, but the problem is that now the rest of the map feels too easy.
Anyway, thank you for the replies.

Strong creatures eh? I think because the map that was set onn "Champion' level increased the difficulty and thus increases the numver of creatures. I've reset the part with Level 1 creatures and stregth not exceeding 100. Should be easy by now.

May I take this opportunity to ask whether you're playing the version 1.2 or 1.11. If it's the earlier version, may I advice you to download the latest version as 1.11 has a big bug in it.

[Mamamia]

I was already playing version 1.2 of your map.
