Mind Wipe (5e Spell)
From D&D Wiki
|Casting time:||1 action|
|Range:||30 feet, Single target|
The caster wipes the target’s memory of the past 10 minutes on the target's unsuccessful Wisdom save. Targets whose minds are wiped will not know that you wiped their memory, and may not be hostile if they were in the time that was erased. On a successful save, the target's mind is not wiped and may realize what you did if they pass an additional Wisdom save. At this point they may turn hostile.
