Wand of Magic Missle

This wand has 7 charges. You can use an action to
expend 1 or more of its charges to cast the magic
missile spell. For 1 charge, you cast the 1st-level
version of the spell. You can increase the spell
slot level by one for each additional charge
you expend.
The wand regains 1d6 + 1 expended charges daily
at dawn. If you expend the wand's last charge, roll
a d20. On a 1, the wand crumbles into ashes and
is destroyed.
