Fatal Aria
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 untyped damage. If this brings it to 0 Hit Points, it dies instantly.
Traits
This indicates abilities from the bard class.
An action with this trait requires a degree of mental concentration and discipline.
An effect with the death trait kills you immediately if it reduces you to 0 HP. Some death effects can bring you closer to death or slay you outright without reducing you to 0 HP.
This effect alters a creature's emotions. Effects with this trait always have the mental trait as well. Creatures with special training or that have mechanical or artificial intelligence are immune to emotion effects.
Focus spells are a special type of spell attained directly from a branch of study, from a deity, or from another specific source. You can learn focus spells only through special class features or feats, rather than choosing them from a spell list. Furthermore, you cast focus spells using a special pool of Focus Points—you can't prepare a focus spell in a spell slot or use your spell slots to cast focus spells; similarly, you can't spend your Focus Points to cast spells that aren't focus spells.
A mental effect can alter the target's mind. It has no effect on an object or a mindless creature.
