A foul corruption of Dendar the night serpent's powers, this staff is able to constrict around a person's dreams, stringing them up like a marionette. 

When this staff is activated, it creates a bubble centered on it with a 1000-ft radius. All sleeping humanoids in the bubble begin sleepwalking, their physical actions under the control of the staff wielder. They have the stats of a zombie, and if they lose half their health they wake up, the spell dissipating on them.

Humanoids that do not sleep, such as elves and warforged, do not fall under the staff's control, but do experience severe discomfort and nausea as the staff attempts to worm it's way in to their mind. Any humanoid that is taking a long rest but not sleeping (such as a trance) immediately takes 1 level of exhaustion and their long rest is interrupted. 

The staff has 5 charges, and restores 1d4 at the next dawn. The wielder can also restore 1d4 charges by expending a 8th level spell slot.
