Cordyceps Whisper

You implant a living filament of mycelium in the target’s nervous system. The target must make a Wisdom saving throw. On a failed save, the target is charmed by you for the spell’s duration. While charmed this way, the target obeys simple verbal commands you issue (no actions that would obviously cause the target to harm itself severely). You can use your action on subsequent turns to issue a new command; otherwise the target repeats the last command. The target may repeat the Wisdom save at the end of each of its turns, ending the spell on a success. If the target takes damage from you or an ally, it gets advantage on its next save. A creature that succeeds on its initial save is immune to Cordyceps Whisper for 1 hour.
