You hold two needles aloft connected by a sinew cord in front of your intended targets. A black thread then appears between them. The target of the drain takes 4d8 negative damage, with a Will save each round for half. The other gains regenerative warding equal to the damage actually dealt that round and can make a Fortitude save to resist this harmless effect. The spell lasts for the duration, though can be ended early if the targets move beyond the maximum distance between them.
