Popis
You focus the decaying essence of impending cosmic death onto a point of your choice within range, draining life from all beings. Each creature within a 20-foot radius sphere centered on that point must make a Constitution saving throw. Creatures take 4d8 necrotic damage on a failed save and their speed is halved for the duration of the spell. Creatures that succeed on the saving throw take half damage and are not slowed by this effect.
A target which fails the saving throw must also make a Constitution saving throw at the end of each of its turns, or take an additional 2d8 necrotic damage. On a successful save, the target takes no damage and the spell's effect ends for that creature.
