There are many different ways to play your character in Vampire: The Masquerade - Bloodlines 2. Ventrue rely on the rise-and-fall mechanics of their Layered Fortitude, building up a defense to take on stronger opponents, while using abilities to dominate weaker foes and make them fight their friends or even kill themselves. Each clan has a straightforward way of playing, and does not require ability optimization. At the same time, if you want to, you can customize your playstyle by visiting certain important vampires throughout Seattle, who are sworn to assist you by offering their Blood to help you unlock abilities from their Clan.
Abilities from other clans may cost more AP depending on how well they align with your clans Disciplines. The Ventrue Disciplines are Dominate (the supernatural ability to control others) Fortitude (the ability to resist physical and mental attacks) and Presence (the supernatural ability to attract, awe, or terrify). If a Ventrue would try to unlock the Brujah ability Taunt, which is part of the Presence Discipline, it would cost less AP, than if they attempt to unlock an ability from a Discipline they don’t already have, such as Obfuscate. Unlocking additional Clan Perks will make them stack, so you can collect them all if you wish, elevating your power much closer to elder level.
Activated abilities and the Clan Perks can be learned from the other clans, but your clan passive can not. This means that while you can combine abilities and features from other clans in hundreds of different ways, your Ventrue playthrough will remain different from playing as another clan who branches into Ventrue abilities.
