It just occurred to me that using Maho seems relatively... safe in this edition. The bloodletting usually associated with it seems to be mostly narrative, unless the maho-tsukai chooses to channel (in which case, it does inflict a bit of fatigue), and the nastiest side-effect is limited to the spiritual backlash, which can be avoided if you're careful.
Now, the backlash itself can hurt a lot, and Taints the maho-tsukai with no hope of resisting it. 5 balcklashes and you're Lost for good.
But aside from that, I did not see anywhere that practicing Maho was a sure way of becoming Tainted at all! Someone could safely practice it for years and not have a single Ring with the disadvantage. Is that how it works or am I missing something? What incentives do the Kansen have to lure the maho-tsukai into accepting the "Dark Lord's blessing"? Currently, only Grip of Anguish gives a slightly better damage rating linked to the number of Tainted Rings that the caster has. That does not seem worth the risk of being caught
especially since there is no particular bonus in triggering a backlash (unlike, say, with Fire incantations).
