Dungeons & Dragons 2024 (D&D) Spell: Insect Plague

Description: Swarming locusts fill a 20-foot-radius Sphere centered on a point you choose within range. The Sphere remains for the duration, and its area is Lightly Obscured and Difficult Terrain.
  When the swarm appears, each creature in it makes a Constitution saving throw, taking 4d10 Piercing damage on a failed save or half as much damage on a successful one. A creature also makes this save when it enters the spell's area for the first time on a turn or ends its turn there. A creature makes this save only once per turn.
