Strive to ensure that the Ghost Device is in its optimal state when being forged!
The Sacred Radiance Bone Fragment's pollution function, "Blessing of the Sacred," turns the bone fragments into a bone chain.
The serpent-like bone chain, when attacking a target, would provoke the evil thoughts within the target.
Under a barrage of continuous attacks, the Sacred Radiance Bone Fragment could even tempt the target to release the evil thoughts inside.
The target, releasing evil thoughts, has their mind controlled by them.
It's akin to entering a berserk state, where combat capability indeed gets significantly boosted.
However, for a strong warrior, this would undoubtedly make them easier to handle.
A true warrior values flexible combat thinking and a sharp mind over sheer power,
to adapt to all possible sudden circumstances that may arise during combat.
