Staff of Hades (5e Equipment)

Staff, legendary (requires attunement)

This staff has five charges. As an action, you can spend a charge to fire a bolt of fire at a creature you can see within 60 feet of you. Make a ranged spell attack roll using your spellcasting ability. On a hit, you deal 3d8 fire damage and the target must succeed on a wis saving throw based on your spell save DC or become insane, gaining a form of short-term madness. The target can repeat the saving throw at the end of each of its turns, ending the effect on a success. Upon expending the staff's final charge, you must make this same saving throw.
The staff regains all expended charges daily at dawn.
