They successfully remove the mask, but subduing the Acolyte is unsuccessful. The Acolyte will escape, though she'll sustain some injuries. You can determine both the Acolyte's injuries, as well as your own characters in the ensuing scuffle. They will not be fatal.

Regardless, their failure is not without value: they'll notice that this Acolyte's features are surprisingly normal and that the mask is missing the needle-like prongs. The Acolyte is a young woman about Ciri's age. It appears the odd appearance caused by the pronged masks are limited to select individuals. She will drop a medium-sized empty glass jar while fleeing. They can keep the jar.
