Arena Vaulted Ceiling (single)

Description
It is said that nobody is truly home until they have a roof over their head. Across the civilizations of Hyboria, rooves are made from a diverse number of materials - from clay-fired tiles warmned in the kilns of Agarapar to the roughly thatched rooves of the Nordheimers. In the Exiled Lands, however, materials are limited. Something to keep the sandstorms at bay and the bat demons from swooping down and snatching people while they sleep is probably good enough. Weapons barely chip it and even explosive powder is not enough to weaken it in a single blow. Siege weapons or divine intervention are really the only way to bring down walls this strong.
