If you have a friend with a titan or have one yourself, you are in luck. My friends and I were attempting the level 34 prison of elders with level 32/33 characters. As expected, we were struggling at first, but then I came up with the idea of using the titan's bubble with armor of light to avoid taking damage from his enrage ability. The armor will reduce slowly while in the bubble because of the lingering fire damage, but do not worry -- all you have to do is jump out of the bubble (preferably up), and get back inside. Be sure to put on the ability to produce orbs when your bubble has been shot, and hide in the area in the back/left with a clear view to the ogres and boss. This allows you to create orbs for your friends, so they can create orbs for you to use your super again. The helmet of saint's ability to blind the enemy is incredibly useful as well. If you have more than one titan in the game, you can have the other extend the duration of his bubble to be sure of victory. We beat this during our first attempt with this strategy. I am glad I could share my tactics with the community. Good luck!
