While everyone shows their knowledge, here I am still thinking of a different MC. The second chance nobody turned guild leader, thief of the hidden class Soulmancer, keeper of outrageous treasures, unsung hero of the novel "Re: Evolution Online". (Don't know if he was Korean tho.)

Still reminds me of Re-Monster. He learned so many skills the MC eventually gained the ability to join them together. Having a bunch of hand, eyes, body reinforcement change into a reinforcement named after his current race. ie shadow goblins outrageous body reinforcement. (Just an example of how a new ability would be called. The whole of this name had not been used in the novel at the time I stopped reading.)

Here I was thinking of the novel "Shadow Slave" for the second law. He was able to become the shadow and much more.

I was thinking it would be a certain Goblin. Re-Monster

How many among us tho, can say they feel the same way? You are not alone.

More likely that her ability will diminish or be stolen by doing the act.

I remember a book where the MC was placed into a game while comatose and played as a piggy.
