Reinforced Wood is a block placeable by the player in FortressCraft. It is not in the Block Wheel. However, it occurs naturally in every world, inside the Workshop, and can be copied. It can also be placed with the Console Command "Fill Reinforcedwood X Y Z." This option requires a USB keyboard or Xbox 360 chat pad to use.

If all the reinforced wood inside your workshop is removed using TNT, the Fill Command, or the Neoteric Axe, then the next time the player enters their world, it will ask to reset the Spawn Tower.

This block was added on August 10, 2011, with the release of the Workshop in the 1.09 Patch.
