Spider Staff

Versatile
Attacks deal 1d6 extra poison damage on a hit when used to make a weapon attack.
{p/r}{10}With the staff in hand, you can use your action to cast one of the following spells from the staff if the spell is on your class's spell list: spider climb (1 charge) or web (2 charges, spell save DC 15). No components are required.

The staff regains 1d6 + 4 expended charges each day at dusk. If you expend the staff's last charge, roll a d20. On a 1, the staff crumbles to dust and is destroyed.
