Wand of Magic Missiles

This wand has 7 charges. While holding it, you
can use an action to expend 1 or more of its
charges to cast the magic missile spell from it.
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. OOOOOOO
