It's not an outright bad expansion, but incredibly grindy, and definitely not for everyone. It basically adds a dungeon similar to the Dreamer's Maze, which is already in the game, but with a little twist - for every 10 stages, you get a chest that rewards you based on how many orbs you've collected. There's also a new, additional, orb reward system in place, where you complete checkboxes with tasks that multiply your orb rewards for every stage. There's a little bit of story thrown into all of it, but I didn't particularly care for it, myself. Basically, there's an evil that threatens the world. You have to go and defeat it for the sake of everyone. The most positive thing about this DLC is that it introduces new weapons, armor and equipment that are substantially better than the existing ones. It also allows you to up the difficulty of the game, with loot quality scaling accordingly. My personal issue with this new dungeon, is that it only allows you to save your dungeon progress after every 20 stages. I saw someone online mention that this was the perfect amount of stages between each save, but I personally think it's way too long. It takes a lot of time to play through 20 stages, and I had to leave my console in rest mode overnight a few times, so as to not lose my progress. When I was progressing through stage 80 through 100 (final stage+boss), I got lucky and collected two incredibly overpowered weapons. I'd already played for a few hours at this point, was getting tired, and I just wanted to save. There were only 2 stages left until the final boss. I just wanted to get it over with, save and call it a day. The boss is a massive meatshield. It took a long time to get him down to 5-ish % health, and I had to spend all of my restorative items because he killed me in one hit, and my team mates fell like flies. Perhaps predictably, I messed up, just as he was about to go down, and wiped out my entire team in one fell swoop. I lost the super rare items I had collected, and I now have absolutely no motivation to play through the grindy 20 stages that lead up to his fight. So, I haven't actually completed this DLC, but I assume I've seen about 95% of it. Unless, you're really into grinding for weapons and gear, you'll probably want to steer away from this one.
