I found the first necromancer on the east, deep in catacombs of old castle. He was not waiting for me, so I got Stone of Souls quite easily. But as soon as I got it, I felt that it was only one part of the artifact, I have to find another three pieces to gather these relics into one artifact and stop all the madmen who summon evil spirits from the world of dead.
hard to move around when any little touch moves you far of view of the creatures coming towards you. Ad there's no options to lower the speed. Uninstalled it.
