I went in here believing this will be a complaint to the amout of Waterdeep cheese we find around Baldur's Gate
They killed Minthara by plopping down an explosive barrel next to her. She doesn't mind and just waits for you to blow her up from a safe distance. The explosion also does not aggro the entire fort, not even the goblins in the next room. This just feels wrong on every step of the way including how easy all of it is.
I believe people shouldn't be punished for their creativity. I know it sounds strange when you put it this way, absurd maybe but... people have fun this way, if the DM allows it than it's not breaking rules. If you don't want this, don't use such mechanics, create your own traps, a bit further away and lure enemies there.
I, for one, love to hear how people get around difficult encounters, but I am a easy-level kind of player and I find BG3 EA to be impossibly difficult at times - so my voice might not carry as much weight around here
