Rastakhan's Rumble Guide
A silver tongue to accompany her silver daggers.
When you hit her face and she says "Does this mean you're not in?" it made me feel like there was some sort of Tad thing going on where if you played her little drinking game, without hitting her face, you'd get a reward. I had Beneath the Grounds and Gang Up early on with the upgraded Tess hero power, so I was able to beat her via her hero power purely. However, while the "Not in?" line did not trigger, nothing special seemed to happen. Inconceivable!
Have you considered healing her?
That's really lame, I also expected some occult treasure/ reward for the same reason. Trolled! And pls keep using that word 10/10 context
