Ashes to Ashes

When a creature within range that you can see drops to zero hit points, you can imbue the magic of a phoenix into their death to ensure they stay in death. As a reaction you can capture a creature in its moment of death and turn it to ash, preventing it from being reanimated or regenerating.

At Higher Levels. If you cast this spell using a 6th level spell slot, you can choose to allow that creature to rise again from the ashes as an infant in 1d4+3 days. If you use a 9th level spell slot, they rise from the ashes at the age at which they died in 1d4+3 days.
