The Phantom is a boss whose attacks are quick and sudden, so the Silkspear can help you attack them without needing to get close.
Given the speed of the boss, the Warding Bell can shield you while you heal—countering any attacks that come into contact while you bind.
For longer survivability, bring the Fractured Mask and the Magnetite Dice. Fractured Mask will give you an extra expendable life, while the Magnetite Dice can make you invulnerable at random times.
The Reaper Crest's crescent slash can cover a wider coverage and make landing hits a lot easier. If you attack the boss after healing without getting hit, this crest will generate silk balls that you can pick up to fill your Silk gauge faster.
The Hunter's Crest is also viable for this fight. Its swifter moveset allows you to deal faster strikes in a shorter amount of time, but you will need to account for its diagonal Pogo Jumps when trying to pogo off the Phantom.

The Phantom is a secret boss you can find in the Exhaust Organ located in Bilewater. You will need to complete the Mist Puzzle in that zone in order to find it.
| The Sinner's Road Guide | |
|---|---|
| 1 | ![]() To get to the Sinner's Road, you will first need to go to the area to the left of the Greymoor Bellway Station. |
| 2 | ![]() Go up the platforms inside the tower. Instead of going left in the direction of the Moorwing boss fight, get up on the platform to the right. |
| 3 | ![]() Go through the path on the right. Be careful of the Thread Raker patrolling through the next area. |
| 4 | ![]() Jump over the gap and enter the path with the elevator sign. |
| 5 | ![]() Standing on the button will activate an elevator that will drop down in front of the Half-Way Home. You can now use this as a mid-way checkpoint while going to Sinner's Road. |
| 6 | ![]() Continue past the elevator and jump on the platforms until you reach the ledge on the other side. If you keep going right, there is a breakable wall that you can hit to reveal a hidden room. Going down this room, you will find a broken carriage and a Flea NPC stuck in Silk. If you free him, he will return to the rest of the Flea Caravan and you will have access to a spa carriage at the Flea Caravan's location. ►The Lost Fleas Walkthrough |
| 7 | ![]() After you freed the Flea, go back to the ledge. Use the Wall Climb ability to get to the top and reach the path going right. |
| 8 | ![]() Proceeding to the right, you will find yourself at Sinner's Road. The road going to the right is lined with Muckroaches who can deal 2 mask damage if you get caught in their jaws. Use the cages to climb and jump to avoid fighting them. |
| 9 | ![]() Upon reaching the next room you will immediately see two things: the Green Prince stuck in a cage, and a sign to the Bench pointing upwards. |
| 10 | ![]() Wall Climb up to the top where the bench sign is pointing, then enter the path to the right. |
| 11 | ![]() Go to the right and defeat the two flying enemies. Avoid falling into the infested water. If you fall into the water, your Silk Gauge will become infected and the maggots will slowly drain away your Silk. To remove the infection, you will need to fill your Silk Gauge and bind. This will shake away all the maggots, but it will not regenerate any masks. |
| 12 | After defeating the flying enemies, pogo off the three spikes then land on the wooden pier. Climb on top of the broken cage hanging above. |
| 13 | Pogo on the spike to the left of the hanging cage and land on the platform. Defeat the two flying enemies that will appear. It is better to defeat enemies than to dodge past them since they will keep following you while you're in the area, making your climb more challenging. |
| 14 | Once the enemies are defeated, use the spike to pogo to the next platform. After getting on the platform, hang onto the wall on the left then pogo off the two spikes to land on the metal platform. |
| 15 | ![]() Jump onto the metal ledge and defeat the single flying enemy there. Afterwards, drop down to the platform below the locked door. Hit the lever to the left to open the door. |
| * | If you climb onto the wall on the left and pogo off the row of spikes hanging on the ceiling, you will reach the abode of an NPC duo named Crull and Benjin. Talk to them and they will give you a Hunt Wish to fulfill. ► Roach Guts Walkthrough |
| 16 | ![]() Go through the now opened door. Get on top of the cage above then platform to the left. |
| 17 | ![]() Drop down then hit the lever. The cage below will be lowered down you can use it as a shortcut to get to the Bench from the area where the Green Prince is locked. |
| 18 | ![]() Go down below then enter the area where the Bench Sign is pointing towards. |
| 19 | Use the spike to pogo above the infested pond. When you reach the platform, talk to Shakra to buy a map of Sinner's Road. |
| 20 | ![]() After paying the bench terminal, you will find that the bench is stuck and unable to go up. To fix the bench, climb up the wall beside Shakra and break the portion on the upper left. This will open a hidden path. |
| 21 | ![]() Go left then pogo off the swinging spikes to avoid falling into the spike pit. This area requires a lot of timing and patience so use the Drifter's Cloak to hang onto the air longer while you make your next move. |
| 22 | ![]() Once you reach the leftmost side, hang from the wall then carefully slide yourself down. When you are positioned by the string of the spike, dash to the other wall. Do the same strategy for the next two sections. |
| 23 | ![]() When you reach the platform with the two thread spools, go to the right and pogo off the swinging spikes to get all the way to the other side. |
| 24 | ![]() Drop into the infested waters then keep swimming until you see the cogs stuck in the roots. |
| 25 | ![]() Slash the roots off the cogs to set the bench free. |
| 26 | ![]() Climb up the opening above then jump on the platforms to the left. |
| 27 | ![]() Wall climb up the opening and destroy the sticks supporting the platform. Pogo off the spikes to the right to get back to the bench area. |
| 28 | ![]() After resting on the bench, go back to the area on the right and continue your climb up to the top. |
| 29 | ![]() Once you reach the top, jump into the opening above. |
| 30 | ![]() Open either of the metal latches. Once you have climbed out, head left. Avoid falling into the infested waters by pogo-ing off the hanging spikes. |
| 31 | ![]() Climb up the wall beside the patrolling Roachkeeper. Hit the top left to reveal a path to the Mist. |
| Mist Guide | |
| 1 | ![]() The Mist is an area covered in a confusing fog. If you keep going the wrong the way, you will find yourself looping around the area for a long time. To solve the Mist's puzzle, you will need to find the butterflies in each zone and play the Needolin near them. Satisfied by your song, the butterflies will fly towards the correct path. |
| 2 | ![]() While navigating the Mist, you will come across ghost enemies who will chase you around until you leave the area. You can defeat them by luring them into traps, or pogo-ing off them when they dive towards you. |
| 3 | ![]() You will know that you have escaped the Mist when you find yourself running down a long corridor. At the end of this corridor is the entrance to the Exhaust Organ. |
| Exhaust Organ Guide | |
| 1 | ![]() Enter the Exhaust Organ. After going down the hall, climb up the left wall and destroy the silk covering the bench. Use this bench as a spawn point. |
| 2 | ![]() Head to the right then climb up the steaming pipe. Time yourself correctly to avoid getting hit by the steam while navigating through the section. |
| 3 | ![]() When you reach the end of the pipes, go down the lower path to the left then destroy the debris holding up the elevator. This elevator will fall down to the area with the bench and you will be able to use it as a shortcut to the boss if you respawn. |
| 4 | ![]() Climb up the path where the elevator was originally located. Go right then navigate through more steam pipes. |
| 5 | ![]() When you reach the top, going left will take you to the Phantom's boss room. Defeating the Phantom will open a path to the left that will take you to the Citadel. This will get you to Act 2 without fighting the Last Judge. |

If you get hit while the Magnetite Dice is in your crest, there is a chance that you will be shielded from damage. This effect happens at random, but it is still useful to have and may just save you if you are in a tight spot.
How to Get Magnetite Dice and Effects

In between attacks, the Phantom has a few frames where it stands still and you can get a clean hit before they do their next move.

When the Phantom dashes during a Dash Attack or a Spear Throw, you can use this opportunity to pogo off them—getting an extra hit when you can.

Avoid hitting the Phantom when they are holding their spear in front of them. If you hit the Phantom while they are guarding, they will do a counter attack that can cost you multiple hearts.
The Phantom leaps into the air, then throws its spear down diagonally.
The Phantom guards themselves with their spear. If they get a successful parry, it will trigger a counter attack where they lunge forward and back with the spear.
The Phantom dashes forward while piercing the air in front of it 3 times in a row.
The Phantom throws its spear across the arena then dashes after it.
The Phantom jumps up and disappears from sight. Shortly after, a white beam of light appears on a wide section of the arena where the Phantom will slam down—harming anyone caught in the AoE.
After defeating the Phantom, you will gain the Cross Stitch skill. When using the Cross Stitch skill, any attacks made by enemies will be instantly parried, and Hornet will unleash a devastating cross-shaped AoE.

When you enter the mist(the first room), you'll see some white butterflies that you can use the needolin on. Once you do, they'll go to the correct exit. You must follow their general direction and find the exit there, because all of the exits are random whenever you enter a new room or restart.
