From Elite Monster to Dragon (LitRPG)

Kent unexpectedly found himself transported into a game, becoming a low-level elite monster just outside the beginner village. Faced with the imminent arrival of players, he was filled with worry. However, to his surprise, he discovered that he could customize his talents and skills. As a seasoned veteran gamer in his previous life, Kent refused to be a mere stepping stone. He designed himself to be the hardest, most twisted boss in history.

When players ventured out of the beginner village and first encountered this hellish boss, the game forums exploded with complaints.

“Every skill is either crowd control or instant-kill on squishies, with massive AoE damage everywhere. And it even has life steal! Just when we almost take it down, it heals back to full!”
