Chimera Fog

You create a mystical layer of fog that provides mental effects similar to a hangover in a 20-foot-radius sphere centered on a point you choose within range. The sphere is heavily obscured for targets outside the fog; Targets inside are unaffected.

Until the spell ends, a creature that enters the spell's area for the first time on a turn or starts its turn there must make a Constitution saving throw. Targets succeed automatically if they are immune to Poison damage. On a failed save, that creature takes 4d8 Poison damage. On a successful save, they take half as much damage. Creatures are affected even if they hold their breath or don't need to breathe. In addition, targets that start their turn inside the fog become Dazed. This does not apply if they enter the fog during their turn.

Dazed                                                                                                                                                                                                                                                                                                                 

• You can move or take an action on their turn, but not both. You can't take bonus actions.

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.
