Neat dungeon mod that ties modpacks together with unique integration

Quite probably the best dungeon mod for Minecraft
Integration: IDAS has structure integration between a whole load of different mods, so you can find many modded blocks in the structures, unlike most other structure mods. It also replaces Ice and Fire's structures by default with way better ones
Awesome builds: The structures are super awesome looking, the builders are really talented
Gameplay: Dungeons are fun to explore, loot is meaningful, traps and challenges well thought out
Balance: Structures are meticulously balanced to ensure they don't give players an advantage by gutting all the Create tech from them, Brass is quite rare as loot

I have sometimes found bugs where blocks such as fences and walls are wrongly rotated upon generation, other than that I have had no problems with this mod

I admit I don't often use this mod in my own custom modpacks, as I prefer to build my own structures, but I think this mod works really well in modpacks and ties all the mods together.
