Thought it might be an idea to have a threat stating some basic tips - might save the need for too many seperate threads.

If I may start:

Max out somebody's Manipulation as soon as you can, once it's at about 95 you can start selling things back to shops for more money then they were worth.

You can awaken dead enemies and farm them for extra XP. It's kinda funny seeing some poor Tremere getting walloped over and over again. :D

Also, hide your party with cloak the gathering, then sneak each party member behind an enemy and have them all feed simultaneously.
