Main mission - The Tumbledown Court | Act 4 Dungeon Siege III Guide
Last update: 11 May 2016
Notice! If you decided to complete Majority Rules first, go to Act 3.
Go through the portal in Grand Chapterhouse (M21,1) and turn west in the abyss (M26,X2). After going out of the depth you will reach the windy Frostspire Mountain, where you will have to dodge cannon fire and fight with Jeyne Kassynder's soldiers. Inside the cave in the north you will come across a wounded Royalist Sapper (M27,1) who will give you Making an Entrance.
If you follow the path further, you will see a cutscene during which the Royalists lose a battle with the Fanatics. In order to help them, you need to find the cannonball (M27,5) and fire it from the cannon (M27,6) at the Azunites. Afterwards break though the crystal wall (M27,7) and go through the waterfall. There you will meet Ibsen (M28,1), who will help you in completing your mission if you do In Search of Solitude (he will also offer you Untamed Mountain).
After you complete In Search of Solitude, you will be able to move on (M28,X3). There, talk with already-known Phineas and Roderick, who will fill you in on the situation.
Follow the Deep Well (M29) to the Tumbledown Court and talk with the Queen (M30,1). She will give you two more missions: Enemy at the Gates and Uninvited Guests.
