Two points better than my last attempt:
Warmonger (5), Parched (3), Miser (3), Purist (4), Cheeky (1), Unstoppable (3) = 19 points
I missed out on Specialist this time, and was kicking myself at first - using Cleansing to get a magic attack off on Evolvia's 80% phys resist form, which was ultimately unnecessary - then I realized that I had already done the same thing several times on Tormented One, which was
necessary. Why can't all my secondary bosses be Tomithy?
(One perk of doing a vicious version of this - less randomness/scumming, since the bosses are fixed.)
