Duredhel Outskirts: 11 - @EpicPhantom999: I haven’t played this in a while, so I don’t remember all the details, but my setup sounds fairly similar to yours, with the exceptions of using more Arcane Archers and not necessarily “spamming” HEM (just using them a fair amount). It’s interesting that our experiences with Baj’Nimen are quite different. I’m not saying he’s a bad boss though; he still looks (and is) awesome.
Tainted Pit: 8
Bulgur’s Throne: 11
Jokull's Nest: 10
Denas's Castle: 9 (+1) - Alright, I’ll be the first to admit that it’s a flawed level in a flawed game. It’s much too easy. That being said, I really like the cinematic qualities of the level and the fact that it’s the first two-part level in the series (an idea I’ve been thinking about for a LONG time). The boss fight is also really cool, despite being quite unchallenging. The epicness of the Demon makes up for it. Vez’nan is also fun to manage throughout the level. On top of all that, it’s quite fun and replayable due to how you can do almost anything you want. I guess in that sense the easiness is both a blessing and a curse. All that being said, it’s not my favorite level or anything. I just don’t think it deserves to be at 8 already.
