Crust King Khann Boss Guide (How to Beat)

Crust King Khann is a major boss in Hollow Knight: Silksong, located at the top of the Coral Tower in the Sands of Karak. Considered one of the easier main bosses in Act 3, this fight is a test of spatial awareness. Crust King Khann fills the arena with large, telegraphed pillar attacks, requiring you to stay mobile and strike from a distance.

How to Find Crust King Khann

Reaching the Coral Tower requires navigating a tricky platforming section in the Sands of Karak. You will need the Clawline ability to begin.

Start from the Blasted Steps Start from the bench located on the left side of the Blasted Steps, in the area with several hanging rings.
Ascend into the Sands of Karak Use your Clawline ability on the rings to climb up and into the upper room, which leads to the Sands of Karak.
Navigate the Seed Platforms In this new area, you’ll find small seeds. Strike them to create temporary platforms. Continue across the tall room to the right until you can drop to a lower section.
Climb the Main Chamber You’ll enter a difficult vertical chamber. You must precisely strike seeds to create paths and climb to the top of the room.
Enter the Coral Tower Once at the top, head left to reach the Coral Tower. Inside, you will need to clear several locked arenas filled with waves of enemies to open the path upward to the final arena. Use the Elegy of the Deep ability at the summit to initiate the boss fight.

Build & Preparation

This loadout focuses on dealing consistent long-range and passive damage, allowing you to focus on dodging the widespread pillar attacks.

Essential for this fight. Khann often creates distance, and Pale Nails lets you deal reliable damage from afar.

The wider attack range makes it much easier to land hits on the boss, especially when you’re jumping to dodge pillars.

A great alternative for a more agile playstyle, allowing you to dash in for quick counter-attacks between pillar summons.

Excellent for passive damage. Deploy it and let it chip away at Khann’s health while you focus on defense.

Khann pauses briefly when summoning attacks. Use these moments to plant Voltvessels for extra damage.

Provides a crucial safety net, allowing you to heal without being interrupted or taking damage if you misjudge a safe window.

A single-use extra life that can be the difference between victory and having to repeat the climb to the tower.

How to Beat Crust King Khann

This fight is about patience and pattern recognition. Don’t get greedy; prioritize dodging and use your ranged abilities.

Watch for the Dust Cues Every single pillar attack is telegraphed by a cloud of reddish dust or smoke. This dust indicates both the location and the direction of the attack. Make this your primary focus.
Stay at Mid-to-Long Range Khann is designed to be fought from a distance. Use Pale Nails as your main source of damage and stay out of his immediate vicinity unless you see a clear opening.
Jump and Pogo for Offense When Khann summons horizontal pillars, a simple jump is often enough to dodge them. Use this airtime to get in a downward pogo strike or an aerial nail attack.
Punish the Stuns After taking enough damage, Khann will be stunned. After the second stun, he enters a final phase where his attacks become significantly faster. Use the first stun to heal and deal heavy damage, but be prepared for the speed increase after the second.

Attack Patterns & Counters

All of Khann’s attacks are based on summoning spiked coral pillars. The key to countering them is to watch the dust telegraphs.

Coral Pillar Skewer

Ranged / AoE

A cloud of dust appears at the edge of the arena, followed by a massive coral pillar shooting horizontally across the screen.

Counter: The dust telegraphs the height of the pillar. Simply jump over it or stay on the ground if it’s high up. You can often get a pogo strike on the boss as you jump over.

Erupting Coral Pillar

Ranged / AoE

Dust erupts from a spot on the floor, and a pillar shoots straight up to the ceiling.

Counter: As soon as you see the dust on the floor, dash away from the spot. There is a generous window to react.

Pillar Cross

Ranged / AoE

Two dust clouds appear, indicating two diagonal paths. Pillars then erupt along these paths, forming a large ‘X’ across the arena.

Counter: The corners of the arena are usually the safest spots. Identify the ‘X’ pattern from the dust and move to an open quadrant.

Coral Fall

Ranged / AoE

Multiple dust clouds appear on the ceiling, followed by a rain of short pillars falling straight down.

Counter: The gaps between the falling pillars are always safe. Watch the dust clouds on the ceiling and position yourself in a clear vertical lane.

Coral Overgrowth

Ranged / AoE

The boss summons numerous short pillars from both the floor and the ceiling, heavily restricting movement in the center of the arena.

Counter: This is a space-denial move. Retreat to the edges of the arena and focus on dodging. Use Pale Nails to deal damage from a safe distance while you wait for the pillars to retract.

Rewards

Upon defeat, Crust King Khann shatters, leaving behind a valuable upgrade.

Encrusted Heart: A powerful permanent upgrade. (The specific effect can be detailed once known).
