Range 30 feet; Targets 1 creature

You perform music so perfect that the target may die of joy or sorrow. Once targeted, the creature becomes temporarily immune for 1 minute. The effect of the spell depends on the target's level and current Hit Points.

• 16th or Lower The target dies instantly.
• 17th If the target has 50 Hit Points or fewer, it dies instantly; otherwise, it drops to 0 Hit Points and becomes dying 1.
• 18th or Higher The target takes 50 damage. If this brings it to 0 Hit Points, it dies instantly.
