Wand of Magic Missle

This wand crackles with magical energy, all of it funneling throughout the want and out the blue end of
it.

This wand has 7 charges. You can use your action
to cast Magic Missile from the wand and expend 1
(1st level) to 3 (3rd level) charges.
This wand regains 1d6+1 expended charges each
day at dawn. If you expend the wand's last charge,
roll a d20. On a 1, the wand crumbles into ash
and is destroyed.
