When playing on any map templates, in huts, you can only learn: ballistics, diplomacy, economics, leadership, logistics, air and fire magic, mysticism, wisdom, eagle eye, scouting, pathfinding, archery, and luck. However, Toga offers the possibility to expand the list of skills to include all of them, as it should be, based on the properties of this object.
Thank you, I didn't know that.
I think it would be logical to include everything there. I've wanted to play a Kirei with necromancy for a long time (I'm not joking).
