Yeah, where do I even start with this writ. Honestly probably up there in terms of Minogons with how awful it is, especially for the level you are meant to take it at. Let me just give my rundown of what feels unfair.
This dungeon has blobs of enemies, specifically somewhat beefy enemies for the level you're meant to fight them at, I am speaking of course about the troglodyte corpse masters. These guys not only hit relatively hard, they also self-buff and mass buff alongside the Troglodyte clerics, this is also ontop of the fact that typically you can find two or three in a blob stacking alongside the clerics. Now the buffs and debuff spam in and of itself isn't a problem, but this quickly snowballs when you learn that the Corpse Masters also summon three rotfiends, that's three more enemies that have a decent chunk of health, and hit decently hard. This is compounded upon by the fact you usually already are having to deal with five to six enemies within the blobs in this dungeon. Things quickly spiral out of control even further, because the corpse masters aren't the only ones that summon things, ontop of getting six rotfiends dropped on you, when you have to fight two of these guys in the already absurdly large groups, the Champion troglodyte mobs can summon dire spiders, adding even more mobs to the already difficult encounter.
I don't know who designed this writ specifically, but I can say having attempted it on several different characters now including an Ogre Barb with DI's, it just is not fun and quite frankly feels unfair.
