Light Sling

Light Sling
Weapon (sling), common

As an action, you can speak this magic sling's command word and hurl a tiny ball of light at a point or target you can see within 30 feet of you. The ball of light sheds bright light in a 20-foot radius and dim light for an additional 20 feet. On a hit, the ball deals no damage and sticks to the target for up to 1 minute, until the sling is used to hurl another ball of light, or until a creature within reach of the light uses its action to snuff it out (as if snuffing out a candle). If the target is an unwilling creature or an object being worn or carried by one, the creature must also make a DC 10 Dexterity saving throw. On a failed save, the ball sticks to the target for the duration. On a successful save, the ball of light winks out.

The light flew through the air and stuck to something. The light shifted slightly, enough to reveal a gleam and glimmer of moisture on the object's surface as it slowly swayed. It was a chest, by the looks of it. Its rough wooden planks showed years of neglect against the harsh light, but any adventurer worth their salt knows it's what's inside the chest that really matters.

Of course, any living adventurer will also tell you that if the chest looks like it's breathing, it's never worth the trouble.
