Baguette de Pustule

This wand has 1 charge that can be used for its
Mind Bang property. It regains 1 charge 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.
Mind Bang : Pustule emits psychic energy in a
20 ft line. Each creature in that area must
succeed on a DC 13 Intelligence saving throw or
take 11 (2d8 + 2) psychic damage and be stunned
until the end of your next round.
