Wand of Web

From Dungeon Master's Guide, page 212. Found on Magic Item Table F.

Description
Wand, uncommon (requires attunement by a spellcaster).

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.
