Staff of Harming

Staff, very rare (requires attunement by a cleric)

This staff has 10 charges. While holding it, you can use an action to expend 1 or more of its charges to cast one of the following spells, using your spell save DC, spellcasting ability modifier, and spell attack modifier as appropriate: contagion (4 charges), inflict wounds (1 charge per spell level up to 4th), blindness/deafness (1 charge per spell level from 2nd to 4th).

The staff regains 1d6+4 expended charges daily at midnight. If you expend the last charge, roll a d20. On a 1, the staff causes you 4d10 necrotic damage and regains 1 charge.
