Can-Trip

You create a pile of cans or other tripping hazards on ground that you can see within range. Until the spell ends, the objects fill a 5-foot square. Any creature which moves into the square’s space or attempts to leave it must succeed on a Dexterity saving throw or fall prone. A creature can only be affected by this spell once per turn.

Creatures which are either immune to the prone condition or already prone are immune to this spell's effects.

Cantrip Upgrade. The spell does damage when you reach levels 5 (1d4), 11 (2d4), and 17 (3d4). In addition, the spell can affect adjacent 5-foot squares when you reach levels 5 (2 squares), 11 (3 squares), and 17 (4 squares).
