I absolutely love the rewards to the Daemonheim task set, especially the extra PGT, potion bind, and free laws/cosmics. I like that we've been given options in terms of opening doors in the form of portents (divination) and free potions. We'll be updating our requirements in DGS for October, likely requiring only the medium task set complete, but heavily suggesting the elite set, too.
The tasks themselves are mostly easy, and the level requirements are far easier than most other task sets. The two tasks that are difficult, though, are practically unbearable: the frost dragon and the sagas. It took me around 40 small and medium floors to find my frost dragon, and the sagas are a pain in the ass without a detailed guide and a lot of patience for clunky controls.
All in all, I'm very happy with the set. Hard mode is also interesting because it forces the team to be very careful with gate placement such that they don't get stuck in any unnecessary rooms, and it definitely tests their ability to deal out damage as efficiently as possible. I don't see it becoming too popular, but we'll be adding a hard mode section to the official dungeoneering records sheet nonetheless.
10/10, but I'm still waiting for my dungeoneering finale, Jagex.
