Why are we able to attack Brax? It hardly serves a purpose other than punish those who missclicked. It seems so random too. Sometimes I'll left click him to sell him an item... other times my character will just decide to take a swing at him... and god forbid you right click and cast a spell or a bolt. I propose a warning pop-up "Are you sure you wish to attack Brax?"
I've never been able to swing at Brax, but a prompt would be nice. I think he should also be immune to splash damage from spells etc. while he's friendly.
