Suggestion

Casting Time: 1 action; Range: 30 feet
Components: V, M (a snake tongue and a bit of honeycomb)
Duration: Concentration (Up to 8 hours)
You suggest a course of activity, magically influencing a creature that can hear and understand you. The suggestion must be worded so the action sounds reasonable. Asking the creature to harm itself ends the spell. If target fails a Wisdom save, it pursues the course of action to the best of its ability.
