TheHall of the Twisted Warlordis the final Tier 1 Abyssal Dungeon players will experience inLost Arkbefore making it into Tier 2, and it’s also the first “real” Abyssal Dungeon in terms of mechanical complexity and difficulty. Players will need to be at least460 Item Levelin order to enter, and the rewards they’ll get for clearing this Dungeon (and possibly purchasing the Bonus Chest at the end) will allow them to craft their Legendary Tier 1 Gear and/or Accessories.

Just like most of the other Abyssal Dungeons inLost Ark,both Stages of the Phantom Palace Abyssal Dungeons are modified versions of the Dungeonsseen in the Main Storyquest,with Rohendel being the setting this time.However, for Hall of the Twisted Warlord, players will need to worry about beating thePhantom Legion’s Rook and Bishopas well as thePhantom Legion Kingbefore even thinking about taking onBrelshaza,the final “big bad” of the Phantom Palace (as well as the big bad of some future endgame content not released in the West yet).
Quick & Compressed Refresher Guide
This first section is mostly for those who have already cleared the Phantom Palace previously and only need the shortest of reminders of what the main mechanics of this Dungeon are. Or, alternatively, this section can also be used by playerswho are confident in their MMORPG Raiding knowledgeand don’t require a lot of explanation to understand the mechanics.
First Section: Sealing The Monsters
The reason why the Phantom Palace Abyssal Dungeon is one of the more fondly rememberedpieces of endgame content inLost Arkis largely because of the high amount of fanfare, and the start of the Hall of the Twisted Warlord is no different. The party starts this section by running forward through a hall of constantly changing scenery with buildings springing up out of nowhere and landscapes changing in the blink of an eye.
While running through these obstacles, players will be asked to “seal” a variety of monsters a couple of times in order to open the gate forward, but this really just boils down to clearing out any mobs that spawn.

Second Section: Phantom Legion Rook & Bishop
These two primarily purple Chess Piece Golems are thePhantom Legion Rookand thePhantom Legion Bishop,and they’re the first tag-team Boss Battle players will encounter in the Abyssal Dungeons, though certainly not the last. There’s only really one actual “mechanic” that players need to remember for this fight: the Wipe Mechanic.
Wipe Mechanic
After a couple of minutes (or an absurd amount of damage is done), the Wipe Mechanic will start. When it begins, the Bishop will move to an area of the arena and will begin gathering energy for an attack, stopping all movement altogether while the Rook will move to a random spot at the edge of the arena and start charging a deadly projectile orb.
After they’ve moved, three out of the four party members will notice a large purple circle underneath their feet that damages and knocks back any allies within it. The fourth member should notice that they don’t have a circle like the rest of their party and instead havea crosshair icon above their head.Once the outlier player has identified themselves, they’ll need to start moving.

The goal here is for the player without a purple circle to move to a spot where the Rook’s projectile (which moves in a straight line) will hit the Bishop before it hits the party member.Essentially, they need to put the Bishop between them and the Rook.If done properly, the Rook shoots the Orb, hits the Bishop, interrupts the Bishop charging up their party wiping attack, and staggers them as well. If done incorrectly, the projectile won’t hit the Bishop, andthey’ll unleash an arena-wide attack that instantly wipes the entire party.
Then, near the end of the battle, this mechanic happens a second time, with the slight difference being the Rook summoning chess piece-shaped stone towers around the Bishop in the center.The three party members with the purple circles should immediately break these towers while the fourth party member gets in position.Worst case scenario, the party only has to break the stone towers that would get in the way of the Orb hitting the Bishop. Once correctly done a second time, that’s the last of this mechanic.

Rook
Punch & Swipe
Very standard punch and horizontal swipe where the Rook punches forward, staggering players, and swipes its arm in a horizontal wave, knocking up anyone hit.
Cross-Shaped Belly Flop
The Rook puts a large cross-shaped red telegraph on the ground that slowly fills. Once filled, the Rook literally belly flops into the middle of the cross, dealing moderate damage and knocking up any players still in the red telegraph.
Bishop
Exploding Orbs
The Bishop summons a bunch of purple Orbs randomly around the arena with red telegraphs underneath that slowly fill. Once filled, these Orbs then explode, knocking up anyone hit and dealing moderate damage.
Cardinal Sphere Projectiles
Four spears spawn on the edge of the arena, one in each cardinal direction. These orbs then move towards the Bishop in the middle, dealing low damage to any player in the way. Then, once they reach the Bishop they move back out toward the edge in diagonal patterns at a slower speed, dealing higher damage and knocking up anyone hit.
Cardinal Lasers
Similar to the Sphere Projectiles, the Bishop summons four small orbs directly around it, one in each cardinal direction. Then, four red telegraph lines form (one from each sphere) and slowly fill. Once filled, these orbs release lasers that deal a lot of damage and knocking up players. Directly after the first wave of lasers, the orbs then slightly rotate to the four diagonal directions and fire again.
Exploding Cracks
The Bishop summons bright purple fiery cracks on the ground that explode shortly after they’re formed. They deal moderate damage to any players standing on them and mostly serve as environmental hazards.
Third Section: Defeat The Illusion Legion
Thankfully,unlike the Ancient Elveria Abyssal Dungeon, the mob-clearing sections of the Phantom Palace are pretty short. After defeating the Rook and Bishop, the party then enters the castle and spends a bit of time clearing out waves of the Illusion Legion in the wide-open room they’ll walk into.
There are a couple of annoying Elite mobs to beat here, but, other than that, it’s a section that’s barely even worth mentioning. Once the Illusion Legion is defeated, players can simply walk through the double doors into the room directly before the encounter with the Phantom Legion King

Fourth & Final Section: The Phantom Legion King
Now it’s time for the final boss of the Twisted Warlord’s Hall,the Phantom Legion King.The Sigmund Boss fight in the Ancient Elveria dungeon forced players to communicate a bit and assign directions before the fight, but The Phantom Legion King goes one step further with its wipe mechanic.

Thankfully,outside of its wipe mechanic, the boss is pretty simple,making the fight pretty enjoyable overall except for this one key section. In any case, the Phantom Legion King has two important mechanics, theIllusion Sword Stagger Checkand its defaultStagger Check.
Important Mechanic: Illusion Sword Stagger Check
This is the premier system of this encounter, and the one players will need to commit to memory if they plan to re-run their Abyssals weeklyfor that extra chunk of Goldor those potential Card Packs (one of Lost Ark’s many examples of time-gated content). How it works is pretty simple, at its 16th and 6th remaining HP bar, the Phantom King will teleport to the center of the stage and start this mechanic. It will begin to channel energy, surround itself with a purple barrier, and summon four Illusion Swords. These Illusion Swords each follow a player until they’re picked up.
Essentially, when an Illusion Sword is picked up, the entire party gets the Illusion Sword debuff, and while that debuff is up two things can happen:

To prevent the second situation from happening, this is where the “order” mechanic comes into play. Basically, each player is meant to trigger the debuff by running into their Illusion Sword, start hitting the boss to deplete its Stagger Check bar, and also get rid of the debuff. Then, the next player grabs a sword and repeats this process. Meanwhile, the other party members are expected to kite the floating Illusion Sword following them around until it’s their turn to complete this process.
To put it into simpler steps:
If the Phantom King seems to be making it until its energy is fully charged and is wiping the party, it may be better to switch up the order to put the heavier Staggering classes firstbefore throwing out a much-too-early surrender vote.
Important Mechanic: Standard Stagger Check
The Phantom Legion King also has a normalStagger Checkthat can happen during the fight, but this one is much less punishing than the Illusion Swords one. Players can tell this Stagger Check is coming when the Phantom King gets this red barrier around it and stabs its sword into the ground.
After stabbing the sword,the Phantom King then summons two large cones of constantly exploding cracks in the ground that deal heavy constant damage to anyone standing in them.These cones spawn either north/south or east/west of the Phantom King and will switch to the opposite side after a few seconds. During this time, players should see the yellow Stagger Check Bar appear under the Phantom King. When they do, they’ll need to drain this using Stagger Skills to end this move early as well as open the Phantom Legion King upto some uninterrupted chain-combo damage.
Regular Attacks
Finally, the Phantom King has a good number of visually distinct attacks, which can make the fight seem chaoticsimilar to something like, say, Alberhastic.Thankfully, none of them hurt all too much, and the visual tells for how to avoid them are usually common sense as well.
Description
Double Slash
The Phantom King slashes its sword vertically on its left and right directly in front of it, dealing low damage and staggering players on impact.
Jump Slam & Energy Wave
The Phantom Legion King jumps between one to three times, slamming its sword down at the height of each jump, before finishing the combo with a large conical energy wave attack that also deals moderate damage and knock up.
Dash Attack & Energy Wave
Almost the exact same attack as the Jump Slam & Energy Wave, but, instead of jumping, the Boss does its Dash attack three times before unleashing the Energy Wave.
Illusion Sword Barrage
The Phantom Legion King quickly summons a group of small floating Illusion Swords before sending them all towards a random player, dealing moderate damage to everyone in the impact area.
Large Illusion Sword Summon
Similar to Illusion Sword Barrage, except that the Phantom King summons larger Swords around it in a circular formation before sending them into the sky and off-screen. After a moment or two, these swords come back down in random areas of the arena, exploding on impact. There is a brief purple circular indicator that denotes where they’re going to land.
Spinning Blade Summon
The Boss lifts its sword into the air before summoning a bunch of spinning blades at the edge of the arena. These spinning blades then move toward the Phantom King, dealing moderate damage and stagger to anyone hit. Then, they disappear as they approach the middle of the arena.
Dash & Slam
The Boss quickly dashes forward, sword out, at a random player before teleporting directly above them and slamming their blade down on top of them, dealing moderate damage and knock up to anyone hit.
Sword Projectiles
The Boss briefly charges up energy in its sword, holding it overhead, before slashing at a random player, sending out a wave of purple sword energy that deals moderate damage and knockback. This can be one single wave or three waves in a spread formation.
Hook & Chain
Scarkrill throws out a hook on a chain directly at a player, which causes knockback and a bit of damage. It’s easy to dodge up close, but harder to avoid far away.
Recommended Consumables & Engravings
Similar to the other Tier 1 Abyssal Dungeon, players won’t need to worry too muchabout what Consumables to bring just yet. No Elemental HP Potions, Destruction Bombs, or even Sleep Bombs are needed at the moment. Rather, they’ll do best if they bring:
