according to the lore it is uncomfortable to shift, which is something I need to convey more when Nivel
.
When ever Nivel gets a part of her forcefully removed I make it seem like she goes into a panic and only thinks about getting that limb back. that could be another possible thing pyken fighters might have to suppress in order to detach arms on a regular basis.
And so I don't make too many hindrances (because their fun to think of) we could make it so some pycon might experience certain problems more than others. like some might have an easier time shifting but could have a much harder time detaching limbs. The problems and strengths could probably be tied to their personality, so if their comfortable with change they won't have as bad mood swings after sifting but if there more dependent on others they might freak out more when they lose limbs.

How about the pycon tai chi be something originally invented by pycon flux mages. Meditation helps with magic and if a pycon learned flux they would naturally want to combined it with pyken. It could grow to be used in plenty of different ways, I'm just talking about it's origin.
