Not a fan of adding more detritus to leadership, and ego checks are too fringe. Adding another focus might be overpowered because this is a 5 level class and the power level is already sufficient I think. You want something more mechanical - I will come up with something but its not going to be powerful. The class is designed to accelerate in power as you gain levels and it does that.
That’s right. So metapsionics and augments are in play, especially with the lower level powers.
Craft (all skills, taken individually), Decipher Script, Heal.
I can’t account for every potential entry into the class. I may just say for any other cases “select three skills from the manifesting class that qualifies you to take levels in Master of the Way if your class is not one of the above”.
