Hollow Knight Silksong How to Beat Coral Tower and Crust King Khann

Among the many mysterious locations in Hollow Knight: Silksong, few are as striking and dangerous as the Coral Tower. This towering labyrinth of bioluminescent shells, brittle coral scaffolding, and shifting waterways is one of the game’s most vertical and puzzle-like areas. Players often wonder: how to get to Coral Tower Silksong? And once you're in, how do you navigate its unique threats and defeat the boss at its summit, the powerful Crust King Khann? This guide will walk you through every part of the Coral Tower process, from the moment you discover its hidden entrance, to its platforming and environmental puzzles, and all the way up through the battle with Khann himself.

How to Get to Coral Tower in Silksong

It is not simple to locate an entrance to Coral Tower. While Pharloom's other areas gently push you toward bosses organically, the Coral Tower is behind puzzles and vertical ascents that demand specific abilities. If you have already reached the watery caves to the east of Greymoor, you are close by. The path begins as you make your way through the water caves filled with bubbly enemies and currents. You'll come across a vertical shaft where ledges are just out of reach. At first, it might seem like a dead end, but this is the base of the Hollow Knight Silksong Coral Tower. To continue, you'll need the Coral Lift ability (an upward dash gained from an earlier quest). This in hand, you can dash up the shaft, jump-chain dashing to rise. Near the top, there's a hidden wall discreetly marked with coral symbols. Strike the wall to reveal a passage, and on the far side is the proper entrance to the Coral Tower.

As you walk in, the tone of the game shifts dramatically. The brightly colored coral structures and glowing sea plants are a stark contrast to the darker caves you've been in up until now. Do not be fooled, though; Coral Tower's beauty hides one of the toughest climbing sequences in the game.

Exploring Coral Tower

Inside, Coral Tower presents itself as a massive vertical gauntlet. Imagine an underwater cathedral twisted into a fortress, arches of coral spiraling upward, while glowing bubbles drift along platforms that crumble when touched. The whole structure is alive, and you’ll need to adapt quickly.

Environmental Hazards

Your immediate challenge will be unstable coral terrain. A few of the coral platforms collapse after being stood on for a few seconds, so jumps need to be planned out. Dying here doesn't always mean death, but rather will blast you back several rooms, which is frustrating. The second hazard is shifting water vents. These vertical currents shoot Hornet upward at high speed, sometimes into innocuous platforms, but sometimes straight into enemies or spike traps. Use short dashes to guide yourself in mid-stream and land safely on the ground. You'll also find spinning coral gates that open and shut at timed intervals. These gates will halt you in your path or trap you in enemy fights if you fail to time your approach properly.

Enemies in the Tower

The Coral Tower has its own roster of oceanic enemies. Crustacean drones crawl along walls and ceilings, nipping at Hornet if you get close. Bubble Wraiths hover in hallways, firing arcs of corrosive bubbles. And there are Spined Shellbacks, slow-moving tanks that can clog narrow paths until you kill them or trick them into charging. All of the enemies are designed to exploit the vertical battlefield. Shellbacks prefer patrolling tight platforms, so you must balance fighting them with balancing. Bubble Wraiths attack you during a dash, so punishing reckless dashes. You have to memorize their timing of attack before reaching Khan at the top.

Checkpoints and Shortcuts

The good news is that Coral Tower is not designed to punish exploration indefinitely. Benches are spaced at irregular intervals throughout the tower, enabling you to save progress. Hidden niches also contain shortcuts, broken walls that loop you back down to lower benches, saving you from long climbs if you fall or die later on. Stop to explore side paths. They not only make future runs easier, but they also hide useful collectibles: Shell Shards, crafting items, and even charm upgrades. These can give you the extra boost you need for the next boss fight.

The Summit of the Tower

At the top of the Coral Tower is a vast bioluminescent throne room. The walls are lined with coral spires, tiered like seating, and a mirrored pool in the middle reflects the light. It is the throne room of Crust King Khann, a huge crab-like monstrosity who rules the tower by brute force. Starting the fight is as simple as stepping on a coral gong located in the center of the room. The moment you strike it, the waters become choppy, the ground trembles, and Khann emerges with claws raised.

How to Fight Crust King Khann

The battle with Khann is both a test of combat skill and spatial awareness. His massive size and claw reach dominate the battlefield, and his attacks can control entire zones of the arena. If you’re wondering how to fight Crust King Khann, the answer lies in learning his telegraphs, managing poison projectiles, and using vertical mobility to your advantage.

Phase One: The King Arrives

Khann begins with large, sweeping claw strikes. His initial attack is likely to be a double slam, with each claw slamming the ground individually, resulting in shockwaves on the ground. Diagonally sidestep to get past both. He follows up with coral bursts, with shards exploding in an arc from his claws. The trick here is to be near his body rather than away from it; counterintuitive as it is, the shards are easier to dodge nearer the center. Occasionally, he performs a wave sweep, dragging one claw across the arena to have a churning wall of water and coral wreckage slam crashing. Your best option is to jump and dash across the wave.

Phase Two: The Arena Shifts Khann mixes things up at half health. Pillars of coral erupt from the ground, reshaping the battlefield into areas. These barriers can trap you in narrow lanes, with fewer places to dodge projectiles. He also gains a new attack: the burrow and erupt. Khann dives beneath the earth, and a few seconds later, bubbles and cracks in the ground indicate where he'll come back up. When he does, coral spikes shoot out in all directions. Standing slightly to one side is the best strategy here, never directly above where he dives down. His claw slams also pick up new speed during this stage, with less reaction time for you. Pay close attention to his wind-up animations, as his right claw tends to drop a little sooner than his left.

Winning the Fight

The key to defeating Khann is patience. His large health pool may tempt you to overcommit attacks, but that's where errors compound. Keep to short, controlled bursts of attacks following his large moves, especially the claw slam and burrow attacks. Vertical motion is important. Double jumps, upwards dashes, and wall clings enable you to dodge sweeping attacks while remaining in position for counterattacks. Engaging him on the ground only will have you running out of space in a flash.

Lastly, be careful with your healing. There are moments after his burrow eruption where you can heal one or two times safely. Other than that, dodging takes precedence over healing.

After the Battle

When Khann finally collapses, the arena quiets, and you’re rewarded with a unique crafting ingredient tied to Pharloom’s coral ecosystem. It’s also a key item in one of the side quest chains, so hold onto it rather than spending it immediately. Defeating Khann also stabilizes the Coral Tower, eliminating some of the collapsing platforms and opening up a permanent shortcut back to the base of the tower. This makes return visits less of a slog and rewards exploration even after the boss is gone.

Final Thoughts

The Hollow Knight Silksong Coral Tower is one of the most recognizable midgame areas, condensing platforming challenges, environmental puzzles, and an epic boss battle into one long climb. Discovering how to get to Coral Tower Silksong is only the first step, but conquering it entails learning about the threats therein and preparing for the ultimate test at the top. And when it comes to battling Crust King Khann, the moral is equally straightforward: stay out of his range, move vertically, and only engage when it's safe to do so. Do that, and the coral king will fall, earning you both a valuable reward and the satisfaction of having bested one of Pharloom's toughest challenges.
