I almost hesitate to say it but better now than getting blindsided by a lox while fighting a 2 star spear guy or something close to the end of the journey. Before the swamp, a redo is just a couple hours.
Still, RIP and better luck next time. My last attempt I got a 2 star rancid in my first BF dungeon and it was lights out from toxin even as I ran. Thinking of doing another try soon; I got sidetracked building.
