Ashes to Ashes

You attempt to age a creature of your choice that you can see within range. The target must succeed on a Wisdom saving throw or age 40 years. If the target's age exceeds the typical lifespan for a creature of its type from this effect, it falls unconscious. While under the effects of this spell, the target has disadvantage on all STR, DEX, and CON saves.

At Higher Levels. When you cast this spell using a higher spell slot, the number of years a target is aged on a failed save increases by 10 for every spell slot level above 4th. When cast as a 9th level spell, aging a creature past their typical lifespan causes instant death.
