Two questions for Dunn With This:

1) As an avatar of the dark, does radient/light damage have more effect on her, if hit with it?

2) Garner has an ability called 'Brand of Castigation' (detailed here once you scroll down a bit) that would allow him to 'track' her location. Would he be able to hit her to even place the brand, would it work, and for how long (she's obviously more powerful than him, it makes sense if she can shake it off)
