I missed 1 Angel in the
Light of the Fallen side quest, and I am currently trying to do the
Soul Arbiter's Maze, but died and have to start back from the very beginning. That one will take a long time to do in 1 sitting, and there's no exiting once you start it, otherwise you have to start all over again from the beginning.
I'm also trying to do
The Crucible, but I'm currently getting my ass handed to me! »
/r0/do ··· _ani.gif Just like the Soul Arbiter's Maze, once you start it, the only way out is either Victory, or Death.
