Spell Description

You create a 20-foot-radius sphere of poisonous, yellow-green fog centered on a point you choose within range. The fog spreads around corners. It lasts for the duration or until strong wind disperses the fog, ending the spell. Its area is heavily obscured.

When a creature enters the spell’s area for the first time on a turn or starts its turn there, that creature must make a Constitution saving throw. The creature takes 5d8 poison damage on a failed save, or half as much damage on a successful one. Creatures are affected even if they hold their breath or don’t need to breathe.

The fog moves 10 feet away from you at the start of each of your turns, rolling along the surface of the ground. The vapors, being heavier than air, sink to the lowest level of the land, even pouring down openings.

At Higher Levels. When you cast this spell using a spell slot of 6th level or higher, the damage increases by 1d8 for each slot level above 5th.

Is Cloudkill Good?

Overall Rating: Green. This means that cloudkill is a good spell.

Overall Notes: Not great in an open field but if you can get the drop on an enemy or contain a group of enemies within the spell it can be very effective because it deals damage turn after turn, as long as the caster keeps concentration. It can also be effective to block off a vantage point used by ranged enemies.
