Great Sage

大賢者, Daikenja

Unique Skill Great Sage 「大賢者, Daikenja」 is one of the first two Unique Skills (the other being Predator) that Rimuru Tempest (Satoru Mikami) had on being born into his new world.
It had evolved from Unique Skill Sage during his death, as he thought since he was approaching his forties as a virgin, he must be something much greater than a mere wizard.
