The Cannith Manufactury has been overrun both with warforged loyal to the Lord of Blades and with rogue House Cannith elements loyal to Toven d'Cannith.

Tips and Misc

  • In order to reach the quest entrance in the Cannith Manufactury, you actually have to fall beneath the moving elevator into the subfloor.
  • You have several dialog options when you first talk to the Cannith Guard <Lieutenant> near the start of the quest.
    • Success in any method will convince them to join your side. They can't jump or climb so they won't help you in the vents, but they will help you kill the Bladesworn Warforged group ahead – in fact they will immediately attack them. Additionally, you will get an extra chest at the end of the quest, regardless of whether they survive or not.
      • If you want both chests, it's best to simply convince them to join you, then leave them be and not have them follow you.
      • Failure: They simply decline your offer and end the dialog. Does not aggravate them.
      • Start a Fight or try to open the door: Results in the obvious conclusion of fighting them.
  • You have similar options for the Bladesworn <Lieutenant>:
    • Blade Faith Tenant (Automatically succeeds) – Any Warforged Cleric, Favored Soul or Paladin with their faith-based enhancements are considered high ranking officers in the Lord of Blade's army, and can use this rank to convince the warforged to align with you.
      • Success (by any method) will convince them to join your side. They will only help you with the very first few monsters past the door, then stop. In addition you will get an additional chest at the end of the quest, regardless of whether they survive or not.
    • Start a fight or mess with the door or puzzle – they will attack you.
  • You can deal with the flame/cold trap in several ways:
    • Disarm it, the control panel is next to the runes
    • Turn it off by unlocking the middle 'Off switch' rune (Open Lock or Knock needed)
    • Run through the trap or jump up and run down the ventilation duct (27 Jump required) and turn the 'Rusted Shut-off Valve' next to the trap ( ♦32Normal ♥36Hard ♠40Elite Strength required).
    • Go around the trap through an adjacent ventilation duct if you don't have the STR to turn the valve but your Jump skill is high enough
  • Under no circumstance, should you attack the door on Elite unless you're looking for an Extreme Challenge.
  • You can deal with the security door in 3 ways:
    • Roguish method: Use the ventilation ducts to drop inside the security door room but when dropping down land on the ledge immediately below the ceiling and unlock the Locking Mechanism found on the ledge (Open Lock or Knock needed Normal: 50–51, 62–63 required on Elite). Once Successfully unlocked; you'll need to use (click) the Locking Mechanism once again for the door to actually swing open.
    • Brute force method (attack the door, or insult the warforged): Be prepared for an ultra difficult fight against a huge amount of re-spawning monsters. The objective here initially isn't clear, but what you need to do is continuously kill the Magefire Cannons. They will also re-spawn, but there is a fixed amount of them, roughly 20. Once they are all destroyed, the constant endlessly re-spawning waves of iron defenders and watcher bots will stop, and a warforged titan will appear. The titan can destroy the security door for you with its hammer attack, allowing you to proceed.
      • If the titan is destroyed, a new one will appear a few seconds later, allowing you to progress anyway. Titans will continue to spawn until either the security door is breached, or a titan is killed too quickly (this can cause the next Titan to get stuck behind a wall.)
    • Puzzle method: The other (much easier) way to bypass the security door is to use the rune wheels near it in the correct order. The symbols are random, but you'll find them in a nearby room (this room can be accessed from the vent shaft above, but you must break a grate that has funky targeting – easiest way is to punch it with bare hands). Memorize them before you enter, then solve them, counting from left to right, in the order of first, third, second, and then fourth. Some of the wheels turn other wheels when they are turned, and this order avoids having that effect turn a wheel that is already solved.
  • You can deal with the force field before the hallway leading to final boss fight in 2 ways:
    • Brute force method: Beat down the two Power Relays up the ladders on either side of the force field. It can take a very very long time to destroy them with standard weapons given their massive HP, DR and absorption. Adamantine is highly recommended. The puzzle method can be faster if you can deal with the magefire cannons but are not prepared to deal with the Power Relays.
      • The Power Relays can be disposed of fairly quickly with use of powerful spells on Normal. The Prismatic Ray and Prismatic Spray arcane spells can instantly destroy them. You can bring scrolls to save spell points, or use the Beholder summon from the Shard of Xoriat. On Hard and Elite, they are Red named creatures and instant kills won't work.
    • Puzzle method: The goal of the puzzle is to pull 2 switches to turn off the power to the forcefield (doesn't have to be at the same time). They are up top in the Southwest and Northwest corners and are hard to see if you don't know they are there. For the switches to work they need to be powered at the time they are pulled. Each puzzle wheel routes power. If you turn a puzzle wheel so that power is sent to the next wheel, the walkway between them will also be powered which causes serious electrical damage to anyone touching the walkway. While a wheel is receiving power it can route it to a switch, another wheel+walkway, or nowhere. In the case of the first puzzle wheel on the lower level, it can also route power to the Reverse Light Gravity shaft or cause the shrines to appear. Each of the upper walkways and the shaft are labeled with standard DDO mystical characters as well as at one of the positions of the wheel that controls it. Solving the puzzle with a hireling is simple after understanding what needs to be done. However you solve it, it is a good idea to start by walking around the top walkways destroying the magefire cannons – or disarming them – which counts toward the quest traps disarmed bonus. Follow the step-by-step solution at the right to do it with 2 players. You can also do it with more players by positioning them at wheels when the walkways are not electrified. In the end it will probably be slower than doing it having a hireling turn the wheel behind you after you walk to the next wheel. After both switches are pulled everything powers off along with the main forcefield.
    • NB: Once the force field is down, the shrine that can be activated by puzzle wheel #1 will be gone. There's another shrine before the boss fight, though.
  • Similarly you can approach the end boss fight against Peacemaker in 3 different ways:
    • Roguish method: You must Search for a Control Panel that can spawn anywhere in the room. Disabling the Control panel will temporary affect Peacemaker for about 8–30 seconds (duration depends on difficulty): it will either shut down (it will stop attacking, teleporting and using the invulnerability shield) or it will switch sides (It will attack the other monsters in the room but you won't be able to damage it until its next teleport.) The Control panel will re-spawn somewhere else once Peacemaker returns to normal so you can repeat the process as many times as you want.
    • Brute force method: Attack him, then continue to pursue him and destroy the randomly located crystals to remove his invulnerability shield, continue this until he is destroyed and the quest will be complete. Should your party have a lot of ranged DPS: It is best to position archers/casters on the central platform to range him, and have the melees on the ramp to take on any dogs that spawn. Otherwise pursue him relentlessly with melee until he is destroyed while someone else deals with the hounds. Eventually all the dogs will fall or spawn onto the lower levels, and casters can blast peacemaker from range (only threat to them is from peacemakers blasts itself) If you are standing on the central dais, the dogs can't reach you; this is likely a bug as I've seen them climb over much taller obstacles.
    • Puzzle method: 4 sets of 3 puzzle wheels on the bottom, solving the puzzle will temporary disable Peacemaker for about 10 seconds. Warning: The floor here is electrified and the puzzle will slowly reset once solved. The 3 wheels from each set have to match the symbol above the set in order to solve it. When turning the wheels each one can turn other wheels from the same set (2, 1 or none). The symbol above each set and how each wheel from a set affects the other two is completely random each time you run the quest. Given the complexity of the puzzle, and how fast the boss recovers from the shutdown, this method isn't recommended.
  • In the end fight, hirelings often have an annoying tendency to jump down to the lightning-filled ground floor and get electrocuted. Click the "come to me" button continuously to keep them alive.
    • It appears this floor is no longer electrified on any difficulty.
  • After U13 the number of enemies in this quest was significantly reduced. Iron Defenders no longer spawn in the final fight, they have been replaced with Watcher Constructs.
