So in broad terms, what can Mystics do? The impression I'm getting so far is something akin to a Lovecraft-esq. scholar... someone with one or two abilities that can give them an edge or unusual ability, but not super heroic... is that about right? Plus of course the side issues of people screaming "sorcery" and trying to burn you (and the darkness points you no doubt incur...)
In addition, does being a Mystic mean you lose the ability to pray to the Icons?
