Diablerie, drinking another vampire's soul to gain her strength, in normal Kindred society is a four lettered word; in the Sabbat it is common practice. Likewise, while members of the Camarilla struggle to hold on to their humanity, the Sabbat openly rejects it, harnessing the Beast rather than denying it. Both of these themes will be represented in the next edition of Clan Quest mod.
The ability to diablerize other kindred will be an option available to those that join the ranks of the Sabbat. A number of characters in the game, when caught alone or off guard, can be attacked, and once bested, their strength stolen. There will be a wide collection of NPCs that can be eliminated this way, some old, some new. Each such soul taken must be bested both physically and mentally. However, this doesn't come without consequence! Killing another Kindred this way leaves a permanent scar on the soul and if the spirit of the consumed is not subsumed completely, the player is left open to fits of rage and other unpredictable behavior.
And what exactly does diablerie gain the player? The main benefit is a random dot in any discipline the consumed NPC was proficient in; this includes out of clan disciplines. Likewise, you gain some of their skills and knowledge, gaining a random dot in a talent, skill or knowledge the deceased possessed as well. However, you cannot increase your dots in a T/S/K or discipline in excess of what the departed possessed - this opens the door to injuring your soul for no tangible gain.
Additionally, the humanity system has been changed completely to more closely match the pen and paper system, i.e. minor sins don't affected the truly damned so acutely. Furthermore, in the new humanity system, it is possible to allow your humanity to fall below three, and players reaching a humanity of zero may find they lose themselves completely.
Other paths of enlightenment are still not available; the spiritual change required to accept an entirely different world view doesn't come quickly or easily and simply cannot happen in such a short span of time. As the newest member of the Sabbat, the player may find himself struggling to hold on to their soul, while at the same time embracing the virtues of the Sword of Caine!
