Yep, but the risk is still very high. Why 20% btw? I understand the trouble of playing with Astral and Blood powers (horror marks, curses), after all you disturb immensely superior powers... but Nature? Trying to become a -normal- animal after 7 levels of research in alteration of the bodies, kills or feebleminds 1 out of 5 expert nature mages? That's a thing RPGs' druids do all the day...
