Zone in is from Karak Peak. ( -317, 166, -581 ) Copy/waypoint -317, 166, -581
It's recommended that you have 500 crit chance for this zone.
The walk-through is much the same as the High Keep (Advanced Solo) version, with the exception that the bosses are 3-^, and something is different about Hammy.
Hammy - Great Hall[]
In this version of the quest, Hammy (Heroic) is three-^, spawns an Escaped Swine add, and he poisons you with Swine Influenza.
I died three times before I noticed, but there are (initially inert) Storage Crates literring the Great Hall where Hammy pops. After the encounter with Hammy starts. they become targetable and sparkle green. I can't be sure, but I think they were instrumental in solo'ing the encounter as a Level-100 Guardian : I lured Hammy over to one box, then attacked the box and smashed it. Inside were sacks of something that Hammy seemed to stop to inspect, while I kited-away hitting him with arrows. When he came-free, I lured him to another and did the same. By then the Escaped Swine had added, and I killed him. Suddenly, I was hitting Hammy for X.Ymillion damage hits at-a-time, and he went-down fast after that.
Sub-quests[]
I found the following sub-quests accidentally, and didn't get their locations:
"Priorities" - there is no guide yet, and I was too busy solo'ing in the Heroic to take locations. You find a Guard with a sparkling note beside him. If you click on it, you will be offered this quest. If you accept, you have a list of people to locate/help. You will incidentally find these people as you fight through the dungeon killing-off the mobs to make the bosses spawn, but the mobs with the captives all have feather-quest icons on them. Some of them are in side-rooms that aren't on your path to the bosses, so you have to check every room. The quest will auto-update as you 'free' or find them (dead):
Find Samuel
Find Gelun
Find Denia
Find Halbert
Find S'dera
Find Linya
Required Reading - updates unavailable until zone is reset and reentered
Note that there is one clickable book at ( -109, -78, 44 ) Copy/waypoint -108.52, -77.78, 43.55, on the end of the domino-placed book line, but this is not one of them : Clicking that book knocks-over the domino-line of books and spawns a bunch of flying Unbound Tomes you'll then have to kill. Clearing these does not in any way have any relation to the quest either.
