You hold two needles aloft connected by a sinew cord in front of your intended targets. A black thread then appears between them. From one target life is drained, to the other lift is given. The target of the drain takes 2d8 negative damage, fortitude save every round for half. The other takes the equivalent in positive energy damage. The spell lasts for the duration, though can be ended early if the targets move beyond the maximum distance between them.
