The Void Walker

The Void Walker can be found as a boss in Hollow Knight: Voidheart Edition. He was added in update 1.4.3.5 as an optional boss in the Abyss. A plaque commemorating the Creator of the Void is now in front of the sea of Void in the Abyss. When the Knight reads it and selects "challenge", the Void Walker will climb out of the sea and begin the boss fight. He fights with a scythe that radiates with Void Energy. After being defeated 10 times, the Void Walker will award the Knight with the charm "Void Fire", greatly increasing the length of their Nail and its damage. He will become an NPC after this. Performing Void Spells (Descending Dark, Shade Soul, Abyss Shriek) in front of him will make them look different. While performing Descending Dark, the Knight will cleave down with a giant scythe that deals area damage. While performing Shade Soul, the Knight opens his cloak (similar to Grimm's Fire Bats) and shoots out a large Void Wave. Abyss Shriek will stay the same.
