Character Evolution Systems: Rebirth 4 Holy Bone

28/09/2025

Rebirth 4 Holy Bone

Unlocks at LV1600

The Holy Bone system, unlocked at Rebirth 4, is designed to be embedded into specific equipment parts, granting powerful offensive and defensive bonuses. By collecting and fusing souls, players can customize their build to maximize damage output, bolster survivability, or balance both aspects in battle.

Although the Crimson Legion’s governor was repelled in Kalent, their soul power lingers. Remnants scattered across the Demon Seal Tower can be harnessed within the Holy Bone system, with different soul combinations triggering unique power releases. A total of 7 governors have been discovered, each offering distinct effects.

Holy Bone Fusion & Inlay

Souls play a central role in empowering the Holy Bone system. Souls can be fused to increase their quality, progressing through the stages Green → Blue → Purple → Orange → Red → Gold.

Forsaken	Dull	Tenacious	Eminent	Sovereign	Dominus

Fusion requires 3 souls of the same type and quality, granting random attributes each time.
