Description
The heart of a monster wandering the Fragmentum. Crude material used for enhancement.
Lore
It is a lesion that breeds evil, the impulse to sin. It is the source of the Fragmentum distortion. A heavy blow has caused this heart to stop beating and lose its luster. "Preliminary tests indicate it's some kind of hybrid: One half is primordial, and the other half is something very similar to Stellarons." — Department of Biology, Sarah Castro
Farm it smart
An ascension material dropped by common enemies; craft it up to higher tiers at the Omni-Synthesizer. You need a LOT across characters — farm drop points with Trailblaze Power regularly and NEVER let your Power cap at 300 (pure waste). The quiet resource sink.
