| Archon's Knot|
|Dungeon in Brightwood|
Archon's Knot is a dungeon of puzzles that is accessible by diving from the top of Brightwood Tower into its entrance. To enter, vault over the broken wall near the cullis gate in Brightwood tower.
There is a statue blocking the entrance to Archon's Knot until the player unlocks Wraithmarsh.
Archon's Knot is in a hollow tower that is positioned next to Brightwood Tower. When you enter, you will land in water. There is a gargoyle in the pipe behind you when you land. After you swim across the small body of water, you will arrive in a small room with a range flit switch that you must shoot to activate. It will unlock a room which contains a large square of spike traps like the traps in the Crucible. A flit switch will fly to some shelves in the back of the room that have candles and skulls on them. The trick is that the squares that correspond to the candles in position are safe, while the others will activate and cause you damage.
You may then proceed to a room with an expression statue. To activate this statue, you have to follow the stairs to the nest room and step on the pressure pad. Unlike most statues, this one requires that instead of copying the statue's expression (cowering with fear), you use an expression that would cause him to cower. Any scary expression should work, including Bloodlust Roar but scary laugh, slap and growl do not work. Defeating the statue frees an flit switch that was trapped in a cage next to it. The flit switch then flies up to the next room.
In this room there are more spike traps. This time, unfortunately, the bookcase contains only one candle. In order to cross safely, you must follow the flit switch, which will slowly progress over the safe squares. As you reach the end of the trapped area, you will notice a silver key hovering a couple of spaces over. Don't worry, as soon as the flit switch is in place and the door has opened, the spikes are de-activated and the squares leading to it are safe.
The next room has only a chest, which contains a Cursed Warrior augment. Proceed to the exit. As you leave the cave, you will be on a high cliff overlooking the lake behind Brightwood Tower. Before you dive into the lake next to the cliff, open the chest to find the Daichi, a powerful and fast katana. This weapon is arguably the best weapon in the game stat-wise. As it is the fastest and highest damage legendary melee weapon in the game.
