You throw the magic stone at the target. It strikes and fizzes, causing 1d4 elemental damage of your choice, from the following: Acid, Cold, Fire, Lightning, Necrotic, Poison, and Radiant. After striking its target, the stone instantaneously returns to your hand for your next action. You can also cast the stone without any element, in which case it will cause 1d4 bludgeoning damage (like an ordinary stone).
You create a small distracting shimmer of light. It can be shaped in whatever way you desire, as long as it remains within a 2 by 2 by 2-foot volume. However, any creature within 10 feet of the illusion will see through the deception. As a level 1 spell, this spell will consume a spell slot.
You touch the stone on the target. The target regains 1d4 hitpoints, but cannot heal beyond its hitpoint maximum.
