Daily Punch 4-18-17 Sneaking Powder Wonderous Item for DnD 5e

Someone confused “sneezing powerder” with something else, so here is an idea that came from that!

Sneaking Powder

wonderous item, uncommon

Opening the small bag of this powder and sprinkeling it over your head make you move that much quiter.  For one hour, you gain advantage on all Dexterity(stealth) checks for one hour.

Thoughts?
