Wand of Magic Missiles

The wand has seven charges. While holding it,
you can use an action to expend one or more
charges to cast the magic missile spell from it. For
one charge, you cast the first-level version of the
spell. You can increase the spell 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.
