You toss the scales into the air, and they vanish in a sparkling mist as you indicate your target. Without hesitating, that creature draws and fires an arrow into the fray.

The subject can immediately make one melee or ranged attack. Taking this action doesn't affect the subject's normal place in the initiative order. This is a single attack and follows the standard rules for attacking.

This spell does not allow the subject to make more than one additional attack in a round. If the subject has already made an additional attack, due to a prior casting of this spell, from the haste spell, or from any other source, this spell fails.

Arcane Material Component: A few scales from a snake.
