Xiloscient's Beguiling Boondoggle

You influence a group of creatures to set all their effort towards the idea of performing tasks that accomplish nothing. Choose up to eight creatures that you can see within range and that can hear and understand you. Creatures that can't be charmed or have an Intelligence score of 4 or less are immune to this effect. Each target must make a Wisdom saving throw. On a failed save, a target cannot take bonus actions or reactions, and the only actions they may take on their turn are the Use an Object or Search actions. At the end of a creature's turn or whenever they take damage, they may repeat the saving throw to end the effect.

At Higher Levels. When you cast this spell using a spell slot of 6th level or higher, you can target two additional creatures for each slot level above 5th.
