Same as 5eYou already know this as 5e Incendiary Cloud — This is your Incendiary Cloud, beat for beat -- same 8th-level 20-ft sphere, 10d8 fire on a Dex save (half on success), re-saves on entering/ending your turn there, and it drifts 10 ft away each round.
Summon a drifting 20-foot-radius ember cloud dealing 10d8 fire (Dex half) on entry or turn-start; it moves 10 feet per turn for 1 minute.

You create a swirling cloud of smoke shot through with white-hot embers in a 20-foot-radius sphere centered on a point within range. The cloud spreads around corners and is heavily obscured. It lasts for the duration or until a wind of moderate or greater speed (at least 10 miles per hour) disperses it.

When the cloud appears, each creature in it must make a Dexterity saving throw. A creature takes 10d8 fire damage on a failed save, or half as much damage on a successful one. A creature must also make this saving throw when it enters the power's area for the first time on a turn or ends its turn there.

The cloud moves 10 feet directly away from you in a direction that you choose at the start of each of your turns.
