Black Ice-Reinforced Wooden Wedge

Description
Wedges are used to expand the possibilities of a building. Black Ice-Reinforced Wood is one of the hardest building materials that can be created in the Exiled Lands. 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.
