Deaths Arrow Of Time

You target a creature you can see within range, putting its physical form through the devastation of rapid aging and time or decaying them if they can't age. The target must make a Constitution saving throw of 25 or higher, taking 10d12 necrotic and acid damage on a failed save, or half as much damage on a successful one. If the save fails, the target also ages to the point where it has only 30 days left before it dies of old age. In this state, the target has disadvantage on attack rolls, ability checks, and saving throws, and its walking speed is halved. Only the Wish or Greater Restoration spell cast with a 9th-level spell slot can end these effects and restore the target to its previous age.

 you must say I will bury you just like I've buried this cursed world that has forsaken me. when you say this you must line up your crossbow to the target in question
