Door Guardian Boss

The Door Guardian boss is a difficult fight to adjust to at first, but it gets easier once you get some practice. At the beginning of the fight, it’s frustrating to hit the boss and not do any significant damage. However, the key to killing the Door Guardian is to stagger it and perform fatal attacks.

Gear Setup

What gear you bring to the fight is entirely up to you and should match the attributes you have leveled up. Here is the setup that was used in making this guide:

  • Weapon: Bone-Cutting Sawblade +10 & Big Pipe Wrench Handle
  • Legion Arm: Aegis
  • Amulets: Patience, Strength, & Blue Guardianship
  • Frame: LADA F150
  • Converter: Large Capacity Insulation
  • Cartridge: Arch Break
  • Liner: Workshop Union Certified

The Fight

As you enter the arena, apply fire to your weapon and target the leg. Now, strafe around the boss at a medium/far distance and bait it to attack. Pay attention to the speed of the animations and which attacks have long pauses after they complete. When you feel comfortable, start moving in and damaging the leg for 1 hit at a time.

Eventually, you want to build up to the point where you can deliver charged RT/R2 attacks on the leg to push the guardian to stagger. Many of the close ranged attacks can be dodged to the right, but the timing is tricky since the guardian moves so slow. Once the boss staggers, it will fall on top of you, so move/dodge back. Then, run in and stand to the right of the head for a fatal attack. After 2-3 fatal attacks, the Door Guardian will be defeated, and you can progress through the last chapter.

Door Guardian Attacks

  • Roll: When the guardian rolls toward you, move to the side or block if you can’t get out.
  • Red Roll: If the Door Guardian glows red and slams on its side, it may follow-up with a side and forward roll. Dodge the initial attack to the right and wait for the combo to complete before moving it.
  • Left Slam: The deformed arm will raise up before slamming to the ground, giving you an opening to attack.
  • Right Swipe: When the right arm winds-up in will sweep across the battlefield in a large arc, so stay back and make sure it doesn’t follow up with a slam from the left.
  • 2-Swing Combo: If the left arm swings, it will be followed by a right swing. As soon as the 2nd swing starts, get ready to run in for a quick hit.
  • Foot Stomp: When the Door Guardian raises its leg, move back to avoid getting stomped on.
  • Leap & Slam: If you are far from the boss, it may pull its right arm back, then leap at you and slam down with the left. When this happens, run/dodge to the right.
  • 2-Arm Slam: Finally, if you see both arms raising, they will slam down in front of the guardian and knock you down. Either keep your distance or dodge to the side if you can time it right.
