Temporal Ripple

You throw out a 15ft cone from yourself. All creatures in the area must make a Constitution Saving Throw. On a failure, a creature takes 48 (8d12 + Wisdom Modifier) Force damage, and is aged by 4d12 years. On a success, they take half the damage and aren't aged.

If the target ages by 40 years or more due to this spell, it loses two points from both its strength and dexterity. If it reduces either of these stats to 0, the creature turns to dust and is lost to the ravages of time.

This spell can be reversed by a Greater Restoration/Heal spell. However, any spell short of a Wish comes with risks. Roll a D20, on a Natural 1, the target's lifespan is only restored by half, and cannot be brought back to full; except for a Wish Spell.
