Absolute Radiance

"The light, forgotten. The plague, the infection, the madness that haunts the corpses of Hallownest... the light that screams out from the eyes of this dead Kingdom. What is the source? I suppose mere mortals like myself will never understand."

Absolute Radiance is the final boss of Godmaster in Hollow Knight. She is the perfect form of the Radiance and sits at the peak of the Pantheon of Hallownest.

Behaviour and Tactics Absolute Radiance's attacks are also almost identical to the Radiance's but come at a much faster pace. She also has an altered final phase. Her fight contains the following attacks with any modifications stated:
 * Beam Burst: Absolute Radiance fires near instantaneous sets of beams fired back to back.
 * Sword Burst: Absolute Radiance now summons two sets of swords instead of one, the second is rotated from the first.
 * Sword Rain: Absolute Radiance's swords fall faster and at a shorter interval in Phases 1 and 2. Sword fall speed is the same in Phase 3 but the interval is slightly shorter.
 * Sword Wall: Absolute Radiance's swords travel faster but only in 3 sets in Phases 1 and 2. Sword speed and total sets are the same as the Radiance's during Phase 4.
 * Wall of Light: Absolute Radiance's wall travels faster.
 * Orb: The colour and visuals of the orbs are more vibrant, they travel twice as fast, and take much tighter turns to home in onto the Knight. Absolute Radiance summons these about 1 second apart. She summons 3 to 4 of these orbs.
 * Spike Floor: Absolute Radiance's spikes spawn every 6 to 8 seconds in Phase 2. They are constant in Phase 3.
 * Big Beam: The beam is slightly thinner and becomes dangerous within half a second. The beams also come every 1 second with each beam starting just as the last one ends.
 * Orb Barrage: The only new attack features slower orbs but are constantly fired every 2 seconds. These orbs behave much more like the Radiance's orbs and will disappear if lead off-screen. This attack is only used in Phase 6.

Trivia
 * Absolute Radiance has no proper Hunter's Journal entry. Defeating her unlocks instead the Radiance's entry if it was not already unlocked.
 * During phase 4, when Nail-bouncing on Absolute Radiance when she is at the very top of the screen, it is possible to cause the Void to rise up and fill the screen completely, resulting in continuous damage and death. This is a glitch caused by the game being programmed to start the ascending phase (phase 5) if a certain height is reached. Staying away from the top of the screen during phase 4 will prevent this glitch.
 * This glitch has been fixed in the 1.5.58.11762 PC beta update.
