Enchanter Charm Question

[Halius]

Quick question for a newbie enchanter. Is it worth it to Tash mobs before you charm them at my level (13)? Right now I have just been charming, sending it in on another mob, hiding to break charm and killing both mobs. I have had charms break a few times in the middle of the fight but never died from it. So anyways, is tash really only worth it at higher levels when you are gonna keep the mob for more than one fight? Thank you!
