Hollow Knight

Hunter's Journal


Fully grown Vessel, carrying the plague's heart within it's body..



''The Old King of Hallownest... he must have been desperate to save his crumbling little world. The sacrifices he imposed on others... all for nothing.''

Behaviour
The Hollow Knight is the Vessel that sealed away the Infection. It is one of two final bosses of the game.

Upon breaking the seals on the temple by destroying the three Dreamers, the player is allowed entrance in order to fight this boss. To begin the fight, the player must break the four chains holding the Hollow Knight.



Phase 1
The Hollow Knight has multiple moves:
 * Nail Combo: it slashes its nail at the player multiple times.
 * Infection Pillars: it jumps and tries to strike the player from above, impales the ground when it lands, causing pillars of infection to briefly charge up and then rise from the ground.
 * Nail Lunge: it dashes at the player with its nail pointed forward.
 * Teleport: it warps from one part of the stage to another.
 * Parry: it raises its nail in a defensive stance. If the player strikes twice with their own nail, the Hollow Knight quickly counters with a slash.
 * Infection Shot: it launches orange balls of goo from its chest in a sweeping arc at the player's general direction.

Phase 2
Phase 2 is announced by the Hollow Knight screeching loudly, stunning the player. During the second phase of the battle, the Hollow Knight gains some new attacks on top of the old ones:
 * Self-Mutilate: The Hollow Knight stabs itself repeatedly with its nail. While not a direct attack, standing in range of the nail as it comes through the back of the Hollow Knight's body will deal damage. In addition, it takes almost no damage from the player while in this state.
 * Engorged Slam: The Hollow Knight floats in the air, homing in on the player before slamming down to the ground. This repeats multiple times. After this attack, the Hollow Knight is left vulnerable for a few moments.
 * Infection Barrage: The Hollow Knight will levitate in the air and unleashes orange balls of goo in all directions.

Phase 3
The third phase is announced by the Hollow knight screeching loudly yet again. Depending on the player's progress, the fight will be interrupted, allowing player to access its mind with the Dream Nail, otherwise the fight will continue as normal. During the second phase of the battle, the Hollow Knight gains one new attacks on top of the old ones:
 * Failed Strike: it attempts to strike with its nail, but instead collapses on the floor fatigued.



Tactics
The main weakness of the Hollow Knight is that it is vulnerable to attacks from above. During a Nail Lunge or Combo, jump above its head and Nail bounce a few times while it finishes its attack. If it tries to Parry, simply dash away before it counter-attacks.

While seemingly random, during Infection Shot and Infection Barrage there is a pattern to the blobs, so pay attention and move into safe zones. Dashing can often overshoot a safe zone, so walking is usually safer.

During Engorged Slam, it will home in on the player nearly perfectly if moving in one direction, but will have trouble tracking if it has to switch direction. Don't run away, instead dodge the first slam, then dash under it when it rises for a new slam, then reverse again after it comes down and repeat.

During Infection Pillars, the pillars it creates will briefly charge on the floor before erupting, showing where it's safe to stand. When the Hollow Knight jumps, it's important to be aware of this and look for a safe zone immediately after dodging its downward strike.

The Hollow Knight's Teleport will usually position it far away from the player, so using Vengeful Spirit/Shade Soul during this time is useful to get hits in before it charges another attack. Moving too far from the Hollow Knight makes it more likely to teleport close to the player, so be careful running away to heal.

Under normal circumstances the Hollow Knight is immune to the dream nail and it will not grant any SOUL on a successful hit.

Depending on the player's progress, one of the three endings will play out after the fight. After the ending, the player will spawn at the last Bench rested at.

Trivia

 * It is unknown as to why the Hollow Knight begins to stab itself halfway through the fight. It could be trying to help the player by attempting to kill itself, or it could be trying to further increase its strength by opening up the infection more. It could also be going mad and trying to destroy the infection by itself.
 * It is explained through NPC dialogue that the Hollow Knight could not contain the Infection due to an unnoticed flaw which caused the Hollow Knight to not be "completely hollow".
 * It is implied that, in the First ending, this will also happen to the player - eventually the Infection will leak through again
 * In the Sealed Siblings ending, the player is noted by the White Lady to have become truly hollow due to acquiring the Void Heart, and thus able to fully contain the Infection. Whether this is actually true or another assumption that could be proven wrong remains unknown.
 * During the scene in the Abyss before the player receives the Void Heart, a vessel similar looking to the player character is shown exiting the Abyss with the The Pale King. It is implied that it's the same Hollow Knight fought in the Black Egg Temple, judging by the shape of its horns. It also looks at the player character, possibly feeling sorry for it. This also could hint towards the original not being completely hollow.
 * It is unknown if the Hollow Knight has a second arm, as it does most of its actions with just one arm, and never shows a second arm during the battle. Its shade, however appears to have two hands.
