Bigby's Construction Crew is a ritual introduced in Unearthed Arcana, concerning Strongholds. [Dr395] As an unearthed arcana ritual, it is not considered to be part of normal gameplay.

A veritable army of magical hands appears in the air around you, each armed with tools appropriate to the task to which you set them, from carpentry to masonry. When you perform the ritual, you describe the desired construction in great detail. The hands start working as soon as they appear, and assemble the structure from available material. They can quarry stone and cut it into shape, fell trees and saw them into lumber, and so on. Their range is limited to 1 mile.

The hands may also repair a ruined structure, or salvage the ruined structure to build something new.

The ritual can build a stronghold whose constructed space does not exceed 300 squares. That space can be divided and arranged any way desired but must be contiguous.

With the DM's permission, the ritual may be used for other construction purposes such as building a bridge, carving stairs up the side of a mountain, and other similar tasks.


The ritual doesn't specify what happens when the construction is complete - presumably the hands disappear once the task is done.

The construction time is normally 1d10+5 months or 1d10+5 years. The sidebar associated with the ritual reduces the time by a number of months or years by the higher of your Intelligence or Wisdom modifier.
