Heroes 6 - Discussion

To use a level 1 portal, bring a hero into a town and, after closing the town window, open the hero's spellbook (the spells section on the map). Click on the portal in the town and teleport to any other town. For level 2, the spellbook is opened in the same way, but now there are two spells: the second one will teleport you to the nearest town from any point on the map.
