Could you go through a mountain with boots? The map was a fan-made one, by the way. It was from the time of the first version of the editor. I still think that the mountain model was simply removed/not added with block tiles.
What map is this exactly?

How long ago was Xuda reworked?
Before, her ability would trigger from time to time, randomly. Now she always knows the location of the enemy hero.
It was more interesting before; there was an incentive to level her up. Now you can level her up to level 3 and easily find out about other heroes' excursions.
And also: regarding Valafar's portals. Maybe it would make sense to reduce the cost of the spell? 30 mana is a lot!
Without 30 mana for a portal, there's no point in leveling up Valafar. I don't know about everyone else, but I never had any mana problems with my demon because knowledge drops very often for demons + artifacts.

What imbalance?
Now, by the time you get the knowledge you need (by the time it reaches 4 from the initial 2), by the time you spend it once, by the time it accumulates, by the time you spend it twice...
In the end, the ability becomes completely useless. Either you have to urgently level up knowledge, neglecting other important demon skills.
Now Valafar can place portals anywhere and change the exits and entrances as he pleases at any distance from each other.

The only thing is, the entrance and exit could be made different colors.
