This twisted wooden staff crackles with unpredictable energies.
You must be attuned to this staff to gain its benefits and cast its spells.

While holding the staff, you have a +1 bonus to your Armor Class.

The staff has 4 charges, which are used to fuel the spells within it. 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: mage armor (1 charge) or shield (2 charges). No components are required.

The staff regains 1d6 expended charges each day at dawn. If you expend the staff’s last charge, roll a d20. On a 1, the staff shatters and is destroyed.

Once per Short rest, the user can cast Chaos bolt at first level without expending a spell slot or material components.

Once per long rest, when you roll for the magic wild surge table, and you pass your check, you can instead treat that roll as a natural one. 
If you choose to do so, before rolling on the table, you may also opt to double the result.

Notes: Bonus: Armor Class, Buff, Warding
