Staff of Grabak the Tentacle-Touched

This heavy black staff is cold to the touch and slick as if its carved shaft were alive. The wood is twisted into a spiraling column of coiled tentacles, each ridge etched with fine runes that seem to sink into the darkness rather than reflect it. At its peak rests a pulsing mass of smaller tentacles, bound around a core of lightless shadow that faintly glows like moonless night on still water. When gripped, the staff breathes with a slow, wet rhythm and nearby shadows lengthen toward it.
