Staff of Violet Fire

You create a quarterstaff of pure necrotic energy that blazes with intense purple light; it appears in your chosen hand. If you let it go, it disappears, though you can evoke it again as a bonus action if you have maintained concentration on the spell.

This staff is an extremely unstable and impermanent magic item; it has 10 charges and does not require attunement. The wielder can use one of three effects:

• By using your action to make a melee attack and expending 1 charge, you can attack with it. On a hit, the target takes 5d10 necrotic damage.

• By expending 2 charges, you can release bolts of necrotic fire against up to 3 targets as ranged attacks for 1d8+4 necrotic damage each.

The staff disappears and the spell ends when all the staff's charges have been expended or if you stop concentrating on the spell.
