Wand of Web

This wand has 7 charges. While holding it, you
can use an action to expend 1 of its charges to
cast the web spell (save DC 15) from it.
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.
