Galen's Cane

This cane is topped by an elaborately carved claw clutching a pitch black crystalline sphere.
The cane functions as an arcane focus; and may
also be wielded as a light finesse weapon for 1d4
bludgeoning damage on a hit. The cane has three
charges. On a hit you may expend a charge to
cause the target to make a DC12 Con Save or be
stunned. The Target may repeat the save at the
beginning of subsequent turns.
The cane regains spent charges at midnight.
