Help with Ritual Path Magic

[Raekai]

Ritual Path Magic is something I discovered today, and at first glance, it seems pretty freaking awesome. This is perfect for the type of character that my girlfriend wants to play in a solo campaign with myself as the GM.

I've been reading about it, but I could use a very simple and basic rundown of what I'm getting into.

Also, I need some stranger enhancements and limitations. What if I want Limitation: No Charms? I haven't seen anything like that.

I could use links to other resources, and example rituals.

How can I light a candle?
How can I fly?
Also, will Compartmentalized Mind help with gathering ambient energy while I'm busy punching someone in the face?

Thanks!
