How to fight Radiance?

Learning how to fight Radiance effectively requires mastering one of Hollow Knight's most challenging and visually stunning boss encounters. As the final boss of the true ending, the Radiance demands precise timing, patience, and strategic positioning to overcome her devastating light-based attacks.

Pre-Fight Preparation

Before engaging the Radiance, ensure you have essential upgrades including the Shade Cloak, Crystal Heart, and Monarch Wings. Equip charms like Quick Focus, Strength, and Longnail for optimal performance. Having the Pure Nail or Coiled Nail significantly improves your damage output during this lengthy battle.

Phase-by-Phase Strategy

Phase 1: Platform Combat

The Radiance begins on solid platforms where you can use standard combat tactics. Strike her when she's stationary and watch for her sword rain attacks—indicated by orange markers on the ground. Use the platforms' edges to dodge her horizontal light beams.

Phase 2: Ascending Platforms

Platforms become temporary, requiring constant movement upward. Focus on climbing rather than attacking aggressively. The Radiance's orb attacks can be avoided by staying mobile and using your dash ability strategically.

Phase 3: Final Climb

This phase features disappearing platforms and intense light beam attacks. Prioritize survival over damage—only attack when absolutely safe. The wall-climbing sections require precise timing to avoid the sweeping light beams.

Phase 4: The Void

In the final phase, you'll fall through darkness while the Radiance attacks from above. Stay centered and focus on dodging her light spears while looking for brief attack opportunities.

Key Tips for Success

Maintain patience throughout the fight—rushing leads to mistakes. Practice the platforming sections in earlier areas to improve your mobility skills. The Radiance fight tests everything you've learned about Hollow Knight's mechanics, making it a true test of mastery. Consider exploring other challenging bosses like the Nightmare King Grimm to further hone your combat skills.
