I'm on my way up to fight Anduil and I find one of those awesome puzzle doors with the 3 sided turning pyramids (with the snake, bird, and whale looking thing).

Usually these are fun to figure out, but the clues around the room aren't helping me out none and I've spent around 10 minutes trying LITERALLY all 27 combinations of symbols (3x3x3) to absolutely no avail.

Did anyone else get stuck here or know what I need to do?
