Obtenebration

Obtenebration centers around the manipulation of shadows or darkness. The summoning vampire can always see through their own shadows, except on a botch. When an Obtenebration roll is botched, the vampire succeeds in summoning the shadows, but cannot control them- they are hostile to everyone and cannot be dismissed normally.

The first level allows the vampire to move shadows around, but does not give them physical form. It costs one blood point to activate, and can be used for multiple purposes: A vampire may focus on one effect per turn, but it is not necessary to spend more blood on successive turns in order to create a new effect- giving a bonus to Stealth and then a bonus to Intimidate would only require one blood point, for example.
 * Cloaking yourself in shadow: add one to your stealth rolls and subtract one from ranged attack rolls against you
 * add one to Intimidate rolls
 * subtract one from the perception rolls of everyone else in the scene
 * force mortals and animals to make Courage rolls

The second dot creates a cloud of supernatural darkness. There is no penalty to Stamina, but it is impenetrable to Auspex and Eyes of the Beast.

At the third level of Obtenebration, the vampire can create tentacles from preexisting shadows. (Rolls and cost are as described in the book.) The vampire can also create tendrils that impose a -2 penalty to Stamina and can smother creatures that need air.

The fourth level works as described in the book. No preexisting shadow is necessary for the tendrils, as they come out of the vampire's body.

A vampire using the fifth level of Obtenebration may still activate the previous levels while in shadow form. Without activating the third level, the patch of shadow still has shadow tentacles, but they have the same Strength and Dexterity as the original vampire- essentially, arms that deal lethal damage instead of bashing.
