No, it isn't. But I am really thinking hard how I solved this.
Meh, you should have a major advantage with the trainer. Just try anywhere on the map and see if he walks there. Thanks to unlimited movement. Be sure to advance in time also because sometimes I simply forgot to let time pass to have new options or dialogues pop up ya know. This is the first chapter of Necro 2 and I am currently at the last one, so I am having a hard time remembering. Was this the one underground ...?
Problem is I did not use the spellbook Now coming to the end of SoD with the trainer help.
