Actually, my group has been taking friends into it for the first time as low as 352. As long as they can pick up on the mechanics, it won't be too bad. Until the final boss, which we still have not beat. We have only tried him once, but we will get it soon. All of the other parts are still pretty easy, even if you are below the recommended light level. If you need some help, hit me with a message. We can at least get you to the final boss and get you some good drops to bring up that level!
