Staff of Kerhern

The Staff of Kerhern (also known as The Dungeoneer’s Staff) is made from bronze and copper, and has a marble-like crystal globe at the top. The staff can be used as a +1 quarterstaff in melee, and provides a +1 to spell attack rolls when it is wielded. The staff has 12 charges per day recharging daily at sunrise. If you expend the last charge, roll a d20. On a 20, the staff regains 1d4 + 2 charges.
