Thief's Arrow

With a quick one-word muttering, the arrow knocked in your bow glows with magic.

Convert one of your arrows to one of the types listed below. The next time you fire your bow, you may choose to use one of your enchanted arrows. Enchanted arrows disintegrate after their effects have been resolved and cannot be recovered. If an enchanted arrow is not fired it turns back into a normal one after 3 hours.

Incendiary: The bow deals fire damage instead of what it had previously. The arrow explodes on impact with a 1ft radius, and anything caught in the blast will take 1d4 fire damage. This can light flammable objects.
Force: The target makes a constitution save, on a fail they are moved 10 feet away from whoever shot it. The arrow does no damage.
Smoke: The arrow explodes on impact into a 10ft cube of smoke. The smoke gives half cover to anyone inside it, and attacks that go through it give the target the benefits of half cover. Non-magical fire caught in the initial blast is extinguished. The arrow does no damage.
Moss: The arrow grows a 10ft square of green moss from wherever it landed. The moss stops if it reaches a wall or other obstruction. Walking through this area is completely silent. The moss turns into water after 5 hours. The arrow does no damage.

At Higher Levels. When you cast this spell using a spell slot of 2nd level or higher, you may enchant an additional arrow you have for each slot level above 1st. You may pick a different enchantment for each of them.
