Hey there~

I like the aesthetics and feel of this a lot. 

I was wondering how much overlap if any there is between practitioners of Ki and Mana?

Similar to Psionics must you forego one to use another? Or is it simply 2 different schools of Magic? 

I'm interested in making a battlemage who wished to be a knight but has an exceptionally weak constitution; so they use some lesser ki to become just a bit better than an average person (and nowhere near a knight)

So they focus their talents on mana instead; but retain their envy of knights. 

Is that lore compliant?
