Benetnasch initially appears as a large, beige cone with rounded edges, similar to that of a giant seed. Its size is also significantly smaller compared to previous Septentriones like Megrez and Mizar as it only takes up a 2x2 area on any battlefield. Once Benetnasch splits, its quarters are hollow, and contain parts that resemble the other Septentriones. Noticeable pieces include Phecda's ring, Megrez's bulbous body, and Alioth's purple core. The quarter that contains Benetnasch's original powers, however, is solid, black, and shiny on the inside.
