I've been going through some of the old mod threads that friggin' spambot Dimenofff dug up and I noticed a mod by Turska abbreviated YAHTM on
this thread, and noticed the link still works!
Getting to the point, would someone like to try defeating the Dragon Sisters in this mod with only the Lv.1 Bubbler (Or Lv. 2 if that's too hard)? Currently I'm finding it hard enough with a maxed out Bubbler, so I guess in terms of difficulty, this would be a really tough challenge (Maybe more so than the Flooded Seal Chamber battle?) for anyone to try.
I'll put up my current save file, which'll take you past the first room's hazards.
