Terminal Impact

You alter your gravitational mass as you fall, storing momentum before releasing it in a violent burst upon impact. At the moment of the spell’s casting, you begin accumulating Fall damage for any distance you fall on subsequent turns until you reach the ground. Any Fall damage accumulated in this way is halved when calculating the total Fall damage taken upon landing.

When you strike the ground, each creature within a 20-foot radius of your point of impact that is in direct contact with the same solid surface must make a Dexterity saving throw. On a failed save, a creature takes an amount of Bludgeoning damage equal to double the amount of Fall damage you’ve accumulated, or half as much on a success.
