I viewed Monks in this RP as DBZ characters. "OMG! THEY'RE POWER LEVEL IS OVER 9000!" I don't see why a well trained monk wouldn't be able to use a "Kamehameha"ish beam... or perhaps more interesting, a "Gentle Touch"ish fighting style.

I loosely linked the magic types here to another spiritual system and I think it clarified the concept. Xi is matter, clay, shapeless energy full of potential. Sakra is form, intent, abstract energy that gives shape to Xi. Karma is nature/essence, it imbues the resulting shaped matter with identity, being the difference between an energy ball, ice ball, fire ball, etc...

So. If Monks control only Xi, they are limited to shapeless energy. Body enhancing is easy because the shape is their being, which is so concrete they don't have to imagine it. I mean, even with your eyes closed, you know where your arm is. They can, at higher proficiencies, project the energy outward, in the aforementioned Kamehameha"ish style, because it's a vector starting from the body. They couldn't, however, use things like a Destructo Disk, because it requires a good deal of shaping and even a tiny bit of nature.

So, all in all, Magistrava have to think about what they're doing, and Sepcarim don't. Sepcarim USE magic, Magistrava WEAVE spells.

I hope my thinking is accurate. Oh... and I made a naughty naughty typo when writing Destructo Disk. Hehehhehehehhe...
