Is there a way to permanently charm an animal? is there a way to release charmed animals without getting attacked? I'm starting a beast master character and i don't want to kill my little friends

i don't like to kill the animals i've charmed either. i've always handled it by sending them off before they turn back and remebering not to use the gather party button

What is the class of your character zenith?
Have you ever played with the beast master?
