Memory:Slow shadow

These undead perceive life with incredible intensity through the slowness of their experience. Thus they have a powerful despising lust for both life and speed, stripping their opponents of both through their draining touch, if they can manage to make contact in spite of their slow speed. A human-sized shadow without a body, rising out of the ground. It moves with ponderous motions, as if swimming through thick syrup, but as your hand tries to swing through it it meets a strong resistance. You realize that this patch of darkness is merely slowed by its own inert substance, and this blood of darkness begins to seep into you, clogging your veins and transforming your muscles into wooden blocks.
