== Usage ==
* [[Activate]] a support beam, right-click a [[cave wall]] or [[cave floor]], and select "Reinforce".
== Creation ==* The first log used in creation must be 24kg however the second may be 18kg, however the whole log is used. The shafts required could be made from this second log to save resources.* When creating, the [[quality]] of the shaft affects your success chance.
== Notes ==
* When creating, the [[quality]] of the shaft affects your success chance.* A support beam is required on ''every'' wall of a cave tile (both sides) to prevent the tile from collapsing.
* A [[reinforced wall]] can be mined but not excavated.
* A [[reinforced floor]] can be mined to remove the reinforcement with 21 [[body strength]]. No shard is produced and the slope does not change.
