Slow

You alter time in an area.

Target. Up to six creatures of your choice in a 40-foot cube within range.

Saving Throw. Each target makes a Wisdom saving throw.

Failure. A target is Slowed for the duration. While Slowed by this spell, it can use either an Action or a Bonus Action, not both. Regardless of the creature's abilities or magic items, it can't make more than one melee or ranged attack during its turn. Additionally, if the creature attempts to cast a spell with a casting time of 1 action, roll a d20. On an 11 or higher, the spell doesn't take effect until the creature's next turn, and the creature must use its Action on that turn to complete the spell. If it can't, the spell is wasted.

Success. No effect.

Ending the Effect. A target affected by this spell makes another Wisdom saving throw at the end of each of its turns. On a successful save, the effect ends for it.

At Higher Levels. You may target one additional creature for each slot level above 3rd.
