Banana Peel

This appears to be an ordinary banana peel.  In fact, if you place it on the ground and whisper the command phrase, it turns invisible to all creatures except you.

The next Large or smaller creature aside from you that enters the space containing the invisible banana peel must make a DC 15 Dexterity saving throw.  If it fails, it trips and falls prone.

The banana peel remains invisible after a creature activates it and can be retrieved.  However, it cannot be activated again until the next dawn.
