Something did earlier, so I'm trying to avoid using magic at all for the moment. [He accidentally froze part of a tunnel trying to avoid some of the infected creatures down here, so he's generally keeping his hands off his magic unless absolutely necessary. Including the one or two alchemic items he brought down with him.]

Let me know if you start feeling weird too. I haven't seen much happening to Monsters yet, but it might not be physical given what's happening to Witches.

[Could be something getting into their heads or tempting them into ferality or something along those lines. Either way, it's not something he's seen as yet, even with the close eye he's been keeping on his partner.]
