Stick of Shaking

Wand, common

This stick resembles a crooked, wooden finger. As a result, it's earned the colloquial nickname of a hag's finger. You can use an action while holding this stick to shake it at up to five visible targets that you can see within 60 feet of you. When you do, those targets become outlined with an illusory glow until the end of the turn, making them immediately discernible; this glow is only visible to you and other creatures of your choice that are within 10 feet of you.

Finally answering the age-old question of "how many things can you shake a stick at?"
