To successfully defeat the Watcher Knights in Hollow Knight, it’s essential to employ a strategic combination of melee attacks, spell casting, and precise dodging techniques. Here’s a comprehensive guide to help you conquer this challenging boss fight:

Pre-Fight Preparation

1. Chandelier Strategy: Before entering the chamber, break the chandelier in the boss room. This action will take out one Watcher Knight instantly, reducing the number of foes from six to five. While this step is not mandatory, it significantly eases the battle.

2. Dream Nail Usage: Prior to starting the fight, make sure to use the Dream Nail on any nearby enemies or objects to refill your Soul. This allows you to heal before the encounter and ensures you have enough resource for spells during the battle.

3. Charm Setup: Equip the following charms to maximize your effectiveness:
– Shaman Stone: Increases spell damage.
– Spell Twister: Reduces the Soul cost of spells.
These charms enable you to deal more damage with your spells while conserving your Soul for healing or additional attacks.

Combat Strategy

1. Focus on One Knight: Concentrate your attacks on one knight at a time. Avoid engaging multiple knights simultaneously; the fight dynamically limits you to two at once, making it more manageable to control the situation if you can eliminate them efficiently one-by-one.

2. Avoid Nail Upgrades: Refrain from upgrading your nail beyond the second upgrade before facing the Watcher Knights. Higher nail upgrades increase the knights’ health, making the fight significantly longer and more difficult.

3. Effective Spell Use:
– Utilize spells like Descending Dark, which not only inflicts considerable damage but also grants invincibility frames (i-frames) during the attack. This allows you to evade damage while still attacking.
– Consider mixing spells with nail strikes for a balanced approach. Use nail arts (charge attacks) to quickly deal damage when the opportunity arises.

Dodging Techniques

1. Observation of Attack Patterns: Carefully watch the knights for their attack cues. Their swinging swipe is a common attack that can be evaded by running or jumping over it. The bouncing roll attack targets your previous position, so anticipate its direction and move to avoid it.

2. Timing and Spacing: Always maintain distance between yourself and the knights. This will give you more time to react and dodge their attacks. Aggressively dodge, especially when they initiate their swift, sweeping moves.

Advanced Tactics

1. Pogo Jumps: Use pogo jumps on the knights’ heads to gain elevation. This tactic creates opportunities for powerful Descending Dark attacks while keeping you out of their hitbox for longer periods. It’s a great way to deal damage safely.

2. Final Control: As you chip away at their health, be mindful of the remaining knights. Kill the first one quickly to avoid overwhelming numbers as the next spawns, since eliminating one can trigger the simultaneous appearance of two more.

Conclusion

With diligent practice and implementation of these strategies, you’ll find that the combination of enhanced spells, focused melee strikes, and smart dodging will allow you to defeat the Watcher Knights effectively. Keep patience as your greatest ally; with these steps, victory can be achieved within a few minutes of combat. Good luck!

In Summary:
– Break the chandelier pre-fight.
– Use Dream Nail to refill Soul.
– Equip Shaman Stone and Spell Twister.
– Focus on one knight at a time.
– Use dodging techniques and nail arts effectively.
– Employ pogo jumps for added damage without exposure to attack risks.
