Has anyone gotten this? I can't find it.

Talk to Wolfgang at south entrance to Calpheon. 300 amity for the knowledge.

Need 300 amity with Wolfgang. He is the trade manager at the horse stable in Southern Calpheon.

His interest level range is so great, that it will save immense amounts of energy and time to just wave at him to 300 amity. The 700 amity knowledge can be gained easier elsewhere, so just wave for 300.

Best amity combo I could find:
Will of Elion > Road of Repentance > After Death > Bell Ringing from the City > Evil Gods in Darkness > An Elionian Definition of Heresy
Use tower of will instead of elionian if you're feeling ballsy

Wolfgang is a prick.

Один из самых отвратительных NPC для дружбы, что я встречал...
Проще всего его просто "замахать" приветствиями через F5.
Нужно всего 300 дружбы, второе знание получается путём исследования местности.

Looks like Wolfgang has officially packed up his trade manager hat and passed it on to Eduard! Same location, Eduard has both 300 and 700 amity knowledges, but at least the coordinates haven’t changed.
