ICly, should Hold Person work on PC werecreatures? I have a vague idea that it will work on a mechanics level, but I am uncertain as to whether or not it should actually work. If the answer is that it should not work ICly, I will not use Hold Person on any PC werewolves I should come across.

I don't think it should, but I believe we can make it so they can't be - if it isn't already the case.

We may decide they should be vulnerable to hold person, though... I don't know, bump this thread if your question is not ultimately answered to your satisfaction.

Okay, Hold Person works on PC werecreatures for now it seems. Rather peculiar!
