Staff of the White Well

The Staff of the White Well is a druidic magical weapon which massively increases the power of its wielder. It is inherited by Robyn Moonsinger towards the end of the novel Darkwalker on Moonshae and allows her to cast powerful lightning and fire magic which destroys entire enemy units. Robyn still has the staff at the time of Black Wizards but loses it during the battle to defend the Moonwell, because she is abducted by a flying creature.
