This area as a gorecyclops and a few goblin mages. Take out the mages first before engaging the gorecyclops. You can easily take out the cyclops if you simply stand upstairs. It's most dangerous attack is when it grabs you and slams you helplessly to death.
The area itself is similar to the Midnight Helix area you completed before. There's a sewer area to the southwest that has leapworms and chests, as well as a small cavern on the second floor where there are more chests. You'll also find another recollection tablet near the ledge of the sewer and in the second floor cavern as well.
Before defeating Daimon the first time, you can farm the Cursed Dragon in this area by baiting it with the Rancid Meat Bait. This will enable you to wyrmforge as many equipment as you like, as long as your Arisen wears it. The best tactic against it is by staying inside the sewer area or the second floor corridor leading to a bridge above the sewer. Comestion works wonders against its fragile crystal hear since this attack erupts from beneath. When it flies, you can aim for its heart and shoot it down using arrows or magick projectiles.
