You suggest a course of activity (limited to one short sentence) and magically influence a creature you can see within range that can hear and understand you. Creatures that can’t be Charmed are immune to this effect. The suggestion must be worded in such a manner as to make the course of action sound reasonable. Asking the creature to stab itself, throw itself onto a spear, immolate itself, or do some other obviously harmful act ends the spell.
The target must make a Wisdom saving throw. On a failed save, it purses the course of action you described to the best of its ability. The suggested course of action can continue for the entire Duration. If the suggested activity can be completed in a shorter time, the spell ends when the subject finishes what it was asked to do. On a successful save, the target knows someone tried to influence it with magic and gets advantage on subsequent saves vs. mindtrick, but might not know it was you if others are close by.
If you or any of your companions damage the target, the spell ends.
