Staff of Ancient Penumbra

The staff measures 5 feet in length and 2 inches in diameter, and is crafted of a nigh-indestructible material called substare. This substance might very well be harder than adamantine, but the secret of its formulation has been lost. Its head is carved to form a stylized illithid’s head, with a high, swept-back brow and cavernous sockets where eyes might otherwise be (if gemstone eyes once resided here, they are long lost). The tentacles of the illithid-head meld perfectly with the shaft, itself intricately carved with a multitude of squirming tadpoles, which provide the perfect rough surface for easily grasping the staff. Scrutiny of the tadpoles reveals the four-lobed tails of illithid young.
