I kinda remember someone saying that Rimuru can make a whole planet and life forms on it. Can anyone check this and if true what chapter in the manga or web novel?
SlimeViscous Organism: As a Slime, Rimuru is a monster that doesn't need to breathe, sleep or eat, as he can survive only on the magicules in the atmosphere.

Absorb and Dissolve: Slime-species intrinsic Skills that are inferior versions of Unique Skills Predator and Glutton.
Self-Regeneration: Allows the user to regenerate from injuries which include regenerating lost limbs. An inferior version of Extra Skill Ultraspeed Regeneration.
