Aurora Arrow

You draw the bow used in the spell's casting and make a ranged attack with it against a target you can see.  In place of ammunition, an arrow of colorful celestial light forms along your bow as you draw back on the string.  On a hit, the attack deals radiant damage instead of piercing.  Additionally, a burst of colorful light appears in the area centered on the point of the target occupied.  The light lasts until the end of your next turn, shedding an aura of bright light in a 5-foot radius, and dim light for an additional 5 feet.  An invisible creature in this light is temporarily revealed as the light dances around its silhouette.

If you cast this spell and target a creature standing in light created by this spell, the arrow deals an additional 1d4 radiant damage to the target.

This spell's damage increases when you reach certain levels.  At fifth level, the ranged attack deals an extra 1d8 radiant damage to any target on a hit, and the additional damage the target takes if within this spell's light radius increases to 2d4.  Both damage rolls increase by an additional die at 11th level (2d8 and 3d4) and again at 17th level (3d8 and 4d4).
