Thousand Arrows

Each creature in a 40-foot-radius, 20-foot-high cylinder centered on a point within 60 feet of Zygarde that it can see must make a DC 18 Dexterity saving throw. On a failed save, a creature takes 24 (4d8 + 6) piercing damage and it must succeed on a DC 18 Strength saving throw or its flying speed (if any) is reduced to 0 feet for 1 minute. An airborne creature affected by this spell safely descends at 60 feet per round until it reaches the ground or the effect ends. An affected creature can repeat the saving throw at the end of each of its turns, ending the effect on a success. On a successful save, a creature takes half as much damage but is otherwise unaffected.
