I read a light novel or webnovel, about a dude who got his soul sucked out of his world by an arch wizard that summoned someone compatible with he and his friends Beast Arts and made an artificial human body for said soul to use. The beast art used a magic circle that sucked up the users magic power and created a soul bond with a beast that synchronizes with his soul and created a Griffin Familiar. Said familiar could eat monster cores and sometimes gain special skills associated with the cores. This chapter reminds me of that novel. I forget what it was called. Its been quite a few years since I read it. The Dude also had a soul weapon that formed a scythe that when cuts monster cores had a chance at gaining a new ability too. He was also a well established fire mage too.
