Yes. Right after Houndmaster, run down the stairs and everyone pops their potion just as they hit the last stair. Even with the 15s pots, you can easily make it to the opposite stairwell where you pull the pat before going to the second boss.
So long as you can get past the buggy ass dogs, it really isn't that hard.
First time we tried this, invisibility worked properly and we got gold! Thanks everyone for the help.
