Yeah, Bruno does waken some zombies but that's it.
Other than that he attacks you with the Colt Anaconda and that's it - doesn't use Potence, just Necromancy for the Zombies. I finished playing a Brujah, and this is the first time I fought Bruno. Usually my characters get by the Giovanni Mansion easily with social stats. But I built my Brujah character to be a combat machine, and wow, I bumped all disciplines to 5 - Celerity first, than Presence than Potence - and wow, you kill everyone before they even realize you've been there. The Sabbat mission was very easy.
PS:
I didn't like the fact that if you enter the Giovanni mansion by force, the dodge 3-5 book is not there! Not fair!!
Is there a way to get it if you break in?
