Moving smoke, bounce in domain box

Hey, what should i do to fix this problem?

I have a character hows gonna do like magic like smoke in hes hand, so i parented the Flow % Domain to the hand bone, but when he moves hes arm, the smoke bounces around in the Domain box. you can clearly see that it is inside of a invisible box…

Isnt it possible to make free smoke? no box.

Or who should i fix this? if i just scale up the box the smoke will looked streched out and low res…

Plz help TY!

nvm fpund “Division”

Turn on Smoke Adaptive Domain and the domain will resize itself according to the needs of the smoke.
