The Failed Champion is one of the most unforgiving encounters in Hollow Knight, testing your reaction time, strategy, and endurance. Unlike his original form, the False Knight, this dream-rematch boss is significantly faster, bulkier, and deadlier. His attacks hit for two masks of damage, making survival dependent on mastering dodging techniques rather than relying on healing.

This guide will break down his attack patterns, weaknesses, and the best strategies for emerging victorious against one of Hollow Knight’s toughest foes.

Understanding the Failed Champion’s Mechanics

At his core, the Failed Champion functions similarly to the False Knight, but with drastic upgrades. His health pool and phases operate under the same principle—you must deplete his armor’s HP in each of the three phases before you can strike his weak point. However, he’s significantly faster, more relentless, and far less forgiving of mistakes.

Boss Stats and Phases

• Armor HP: 1080 (divided into three phases)
• Weak Spot HP: 180
• Damage Output: 2 masks per hit
• Attack Speed: Much faster than False Knight
• Main Weakness: Exploitable stagger phase

Just like before, his weak point is completely vulnerable during stagger states, allowing you to freely wail on him. The trick, however, is getting him there safely while dodging his massively improved attack speed and shockwave pressure.

Failed Champion’s Attack Patterns and How to Counter Them

The Failed Champion has a set of brutal attacks that demand precision dodging and awareness. While familiar, they now have extra layers of difficulty compared to the False Knight fight. Let’s go through them one by one.

1. Heavy Bash (Improved Shockwave & Barrels)

✔ What Happens:

• A massive overhead slam that creates a taller shockwave than before.
• Falling barrels drop in all phases, increasing in number as the fight progresses.
• Shockwaves and barrels deal 1 damage instead of 2.

✔ How to Dodge It:

• The shockwave can still be cleared with a simple jump, but dashing is safer.
• If barrels are falling near you, prioritize dodging them rather than worrying about the Knight.
• If you get stuck in a bad position, getting hit by a barrel is preferable to taking a full slam.

2. Crash and Bash (Unforgiving Speed & Hitbox)

✔ What Happens:

• He leaps into the air and crashes down with almost no warning.
• The hitbox is enormous and difficult to react to in time.

✔ How to Dodge It:

• You cannot react in time to dodge this once he’s already airborne—you must preemptively move.
• The best counter is to dash away the moment you see him begin his attack animation.
• Never try to run under him—it’s a guaranteed death trap.

---

3. Jumbo Jump (Phase-Dependent Movements)

✔ What Happens:

• In Phase 1, he only jumps backward.
• In Phases 2 & 3, he can jump forward as well.

✔ How to Dodge It:

• The jump itself isn’t dangerous, but it’s the follow-up attack that matters.
• After a backward jump, he is guaranteed to do a Heavy Bash—use this predictability to your advantage.

---

4. Tantrum Slam (Unchanged but Dangerous)

✔ What Happens:

• Just like the False Knight, after being staggered, he slams the ground repeatedly in a tantrum.
• He always does this from the center of the arena.

✔ How to Handle It:

• This is your safest window to heal or attack from range.
• If you have soul, unload spells while he flails.
• Stay away from the center to avoid unnecessary damage.

Winning Strategy: How to Exploit His Weaknesses

1. Stay Close – Distance is a Death Sentence

While it’s tempting to back away and use the environment to dodge, the Failed Champion’s attack range and speed are too oppressive for passive play.

• Staying close to his feet allows for better reaction time to his telegraphed animations.
• Both Heavy Bash and Crash and Bash can be dodged effectively by dashing the moment he winds up.
• The farther away you are, the harder shockwaves are to jump over—don’t make it harder on yourself.

---

2. Healing Trick – Infinite Recovery During Stagger

✔ Normal healing is impossible while he’s standing, but there’s a cheese method during stagger states:

1. Normally, the Failed Champion recovers from a stagger after a few seconds.
2. However, if you hit him, the timer resets—even if you only strike his armor.
3. Swing at his armor, heal, repeat.
4. For additional soul, use the Dream Nail on his armor in between hits.

With careful execution, you can fully restore health and soul during every stagger, effectively removing the need to play defensively at all.

3. Maximize Soul Usage – Spell Spam Strategy

Because of the stagger-state exploit, you can easily max out your soul pool in every cycle. This makes spellcasting an invaluable tool for damage output.

• Abyss Shriek is your strongest attack—use it whenever you have full soul.
• Spell Twister Charm can be useful here to reduce spell cost, letting you get in more volleys per stagger.
• Dream Wielder Charm allows faster and more frequent Dream Nail strikes, keeping you at full soul without needing direct combat.

Ascended Failed Champion – Harder, But Still Beatable

In Ascended Mode, the Failed Champion gains:
✔ Higher HP (600 per phase)
✔ More aggressive AI
✔ No more floor drop after Phase 3

The core strategy remains the same, but with slight adaptations:

• Sharp Shadow Charm allows you to dash through him safely.
• Dream Wielder + Spell Twister combo ensures you get maximum soul generation for spells.
• Stay away from walls—his attack tracking gets deadlier when cornered.

Even with these buffs, the stagger exploit still works, making patience your biggest ally.

Conclusion: How to Beat the Failed Champion with Consistency

The Failed Champion may be a nightmare at first, but once you understand his mechanics, he becomes a predictable fight.

✔ Stay close to control his positioning.
✔ Dash immediately at any sign of attack animation.
✔ Use the stagger exploit to regain health and soul.
✔ Spell spam when possible, using Abyss Shriek for big damage.
✔ Avoid walls, and don’t try to react to Crash and Bash—preemptively move.

With these strategies in place, you’ll not only survive this brutal rematch but dominate it with confidence. Now, show this bug who’s boss!
