The vessel at the end

The Hollow Knight is the final boss of the standard ending. The fight is emotional more than mechanical. Compared to some optional bosses, the Hollow Knight is forgiving with large openings and predictable patterns.

Sidekick AI suggested:

This boss has long recovery windows. Don't panic. Hit twice after each combo, heal when it staggers or stabs itself. You have more time than you think.

Phase 1: the nail

The Hollow Knight uses big, telegraphed nail attacks. Most can be dodged by dashing through them or jumping over the lunges.

Key attacks

  • Triple slash: Three horizontal swings. Jump or dash behind.
  • Lunge: Charges across the arena. Jump over and pogo off its head.
  • Ground slam: Jumps and slams down with infection shockwave. Dash away from impact.
  • Parry pose: The Hollow Knight raises its nail and pauses. You can hit it freely during this, it won't counter.
Sidekick AI suggested:

It's in the parry pose. Free hits. Walk up and attack. It won't strike back until the animation ends. Get 3-4 hits in.

Phase 2: the infection

At around 50% health, the Hollow Knight becomes erratic. Attacks get faster, infection blobs fill the arena, and the boss starts stabbing itself.

What changes

  • Infection blobs spray from attacks and self-harm. Move to clear ground.
  • Self-stabbing animations are long and free damage windows.
  • The boss staggers more often. Use Howling Wraiths or Abyss Shriek for burst during staggers.
  • Attacks are faster but less accurate. The pattern becomes readable once you stop panicking.
Sidekick AI suggested:

It's stabbing itself. Sprint in and get as many hits as you can. Watch for the infection spray outward, dodge left or right, then keep hitting.

The ending choice

If you have the Void Heart, Hornet will pin the Hollow Knight after a certain number of staggers. You can either keep attacking (normal ending) or Dream Nail the Hollow Knight (enters the Radiance fight for the true ending).

Summary

The Hollow Knight is a fight about patience and reading the openings. Phase 1 is slow and forgiving. Phase 2 is chaotic but full of free damage windows from self-harm. Sidekick AI can call out the parry poses and self-stab windows so you maximize every opening.

Frequently Asked Questions

What charms should I use for the Hollow Knight fight?

Quick Slash + Unbreakable Strength for damage. Mark of Pride or Longnail for safer range. Shaman Stone if you rely on spells. Shape of Unn for healing during openings. This fight has generous healing windows, so recovery charms are less critical than in other endgame fights.

How do I get the true ending instead of the normal one?

You need the Void Heart charm, which requires completing the White Palace and getting both halves of the Kingsoul. When the Hollow Knight staggers and Hornet pins them, use the Dream Nail on the Hollow Knight to enter the dream and fight the Radiance.

Why does the Hollow Knight start stabbing itself?

In phase 2, the Hollow Knight begins stabbing itself, creating infection blobs. These are free damage windows. Attack during the self-harm animations, but dodge the infection projectiles that spray outward.

Is the Hollow Knight harder than Hornet Sentinel?

They're different. The Hollow Knight has more health and bigger attacks but is more predictable. Hornet Sentinel is faster and more aggressive. If you beat Hornet Sentinel, you have the mechanics for this fight.
