How many minutes was that before 'Etta found something she could potentially blow up? Or are we talking seconds here?

On the other hand, would the team let her capture some undying veilfire to craft into some sort of flamethrower weapon, which definitely wouldn't lose containment and kill them all in a glorious green conflagration while travelling through the Deep Roads.

Well, probably wouldn't.

I'm 80... 70% sure it wouldn't. Possibly.

Definitely more than 60% sure, I'm certain of that.
