You use magic to affect up to twelve creatures you can see within the range of the spell, and give some kind of hint of action (at most in the form of one or two sentences) to them.
Mass Suggestion 5e
Classes: Bard, Wizard, Warlock, Sorcerer
Casting Time: 1 Action
Range: 60 feet
Components: V, M
Duration: 24 hours
The target of the surgery specified by you must be able to hear and understand your words. Creatures that cannot be charmed will also be immune to this effect. Your suggestive words must make their behavior sound reasonable. Asking the creature to stab itself, hit the tip of the spear, make it self-sacrifice, or let it do any obvious harmful behavior will directly cancel the effect of the spell.
Each target must make a perception saving throw, and those who fail the saving throw will do their best to perform the behavior you describe. The behavior you suggest may always be performed for the duration of the spell. And if the activity you suggest can be completed in a shorter time, the spell will terminate immediately after the target has completed your requirements.
You can also describe a specific situation that occurs within a duration as a condition that triggers a particular behavior. For example, you can imply that a group of soldiers hand over all their money to the first beggar they encounter. If the conditions are not met before the spell ends, the specified behavior will not be executed.
If you or anyone in your companions hurts a creature affected by the spell, the spell’s effect on that creature ends.
When using the 7th-level spell slot to cast this spell, the duration becomes 10 days. When using the 8-level spell slot to cast this spell, the duration becomes 30 days. When using the 9th-level spell slot to cast this spell, the duration becomes one year and one day.
