I thought I’d ring out the old year with some monsters…vampires, in point of fact. I based the master vampire off of a level 5 wizard (evoker), applying the vampire template. I’ve also BB-ified things quite a bit, so please forgive me if they aren’t exactly like PF core vampires.
Still, these BB versions of vampires are quite nasty, especially with their energy drain and dominate attacks. A standard BB party, unprepared for vampires, could easily face a TPK.
Cheers, and Happy New Years!
