Broken Tower Redoubt is a dungeon in The Elder Scrolls V: Skyrim
Follow the corridor forward and around the first two corners. There is a large room in front of you with more Forsworn: 2 Pillagers.
One is on the lower level and one on the balcony above. Head into the small room across from the entrance to the large room for a potion and a lot of Nord Mead. Head up the stairs and go over to the right. Open the door to move into the next room.
Follow the corridor the turn North. Be careful as there is a Forsworn Pillager as well as a Spiked Wall Trap with two triggers. Keep to either side to avoid the trap's trigger. You can lure the Pillagers into the trap without too much effort.
Follow the corridor into the next room. You will find a locked chest (Novice Difficulty) by the right-hand side bed. Loot that then check over the rest of the room. Gather what you want then start over to the East. This leads to a balcony overlooking some of the earlier dungeon. Straight across from the doorway is a Magicka Potion. Grab that then follow the path to the North and East.
Head through the corridor until you find the stairs leading upward. You want to look up as there are Forsaken on the stairs. Expect at least a few Forsworn Foragers and Pillagers. Be careful as you go up as there are 2 Mages at the top of the stairs in the large room there. There is a trip wire on the first landing below the the Forager. If you trigger it while the pillager is below the trap you can easily take them out. Head through the room after you deal with them.
On the far side of the room you can head up the stairs to the South. This will take you up to the higher level of the tower. This has a landing between parts of the Redoubt. In between you will encounter a Forsworn. Defeat them and then get ready for a boss fight.
Inside the tower you will find a Forsworn Briarheart. If you can turn invisible and get close enough to pickpocket him, steal the Briarheart to instantly kill this powerful foe.
Head to the Northern part of the room. You will find a big chest on the right-hand side of the room. If you are after something, it will be in this chest. You can also find a copy of the book: The Firmament. You can also find Liminal Bridges in this room on one of the tables in the main part of the room.
