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.
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.
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.
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.
