Spirit Subjugation Talisman, aka Soul Subjugation Talisman, was the Heavenly Talisman Sect’s protecting talismans.
It necessitates the soul of a metamorphosis stage (Grade 8) demon beast.[591] [763] It is capable of refining a demon soul’s cultivation and taking it into one’s body to vastly increase their cultivation; the user would have their body become semi-demonic.[776] [854]
Originally created to fix flaws in the Spiritfuse Technique The talisman is refined using the soul of a Metamorphosis-stage Demon Beast. The talismans strength is determined by the grade of the Demon Beast whose soul was used as an ingredient. When used, it allows a cultivator to temporarily increase ones cultivation level and inherit the abilities of the Demon Beast whose soul was used.
