The Hero's Path

So, scouting only increases the view range by 4; I tested it, and it only reveals a small part of the cave. The useless silent stalker, which adds 12 cells, ruins everything.

And how is it implemented in Aglaia's campaign, in the last mission? It seems that the land is revealed while moving, but the sea is not.

There is a function that enables/disables the fog of war separately for land/sea. I try to catch all possible ways for the hero to enter/exit the cave with a mage and switch it at that moment.
