4th-level Spell: Stormcloud

Sorcery/Whispering (Evocation)

A 20-foot-radius sphere charged with crackling lightning and rumbling shockwaves appears centered on a point you choose within range. The sphere remains for the spell's duration; at the beginning of each of your turns, you can move the sphere up to 10 feet in a direction of your choice. The sphere spreads around corners, and its area is lightly obscured and difficult terrain. Creatures inside the sphere are deafened, and creatures within 30 feet of the sphere have disadvantage on Wisdom (Perception) checks made to listen.
Until the spell ends, you can use a bonus action on each of your turns to direct a lightning strike from the sphere's center at one creature you choose within 60 feet of the center. Make a ranged spell attack. You have advantage on the attack roll if the target is within the sphere. On a hit, the target takes 2d12 lightning damage.
After this lightning strike, each creature in the sphere must make a Constitution saving throw. A creature takes 4d8 thunder damage on a failure, or half as much damage on a success.

• At Higher Levels. When you cast this spell using a spell slot of 5th level or higher, the thunder damage increases by 1d8 and the lightning damage increases by 1d12 for each two slot levels above 4th.
