These items are extremely rare or even legendary, and only one of each item can be included in any Dark Eldar army.
This detestable device resembles a sphere of barbed wire, which can be made to explode outward, capturing unfortunates within its agonising embrace and slowly draining their life force. The Dark Eldar find this highly invigorating.
Any models captured by a unit including a model equipped with the Animus Vitae count for five Victory Points each instead of the usual one. Once one or more models has been captured by the character with the Animus, he benefits from +1 WS and +1S for the rest of the game.
