So, after spending about 3 hrs wiping against this thing it has become clear that "Certain classes" are not going to really get this done.

Namely SMN/BLM, as both require you to stand still and pew pew. Demon Wall does not allow this...Almost at all.

Not only do you get the poison on the ground that gives random debuffs and damage but you have the knockback, adds, adds that do large AOEs that do pretty nasty damage and you get the room cut in half.

I am all up for a challenge but Demon Wall is just seems broken.
