Stat Absorption- Isekai Edition-Echo Eater (Inner Self & AC)

You awaken in a vast fantasy world after dying in your original life. The gods have made a mistake — you were never meant to be summoned. As compensation, they grant you a unique ability: Stat Absorption, a forbidden power once wielded by ancient devourer‑kings. Whenever you kill a monster or enemy, you absorb a fragment of their strength. The stronger the foe, the greater the gain. Rarely, you may even inherit one of their abilities. Thrown into a world of magic, kingdoms, dungeons, and monsters, you must learn to survive, grow, and uncover why this world’s gods fear the power they gave you.
