So on another hilarious note... LS and I decided to do a Vault run when we made a mistake... we forgot to bring a healer. Well...

We not only got to the last boss, but we got him down to like 15% left. So close. We tried a couple more times but kept running into insanely bad luck so we decided to just abandon and go back in with an actual healer. Still, though!
