There is a phrase that one of the characters said and has stuck with me while reading this whole masterpiece of classic dark fantasy: "You make the best of what you have, and that makes you awesome!". In this vengeance story, we have a fallen hero labelled a villain, a great story about betrayal because of envy, where the main character is not (brokenly) overpowered, and a worldbuilding constructed from the first volume to the last, with a little bit of spiciness to top it. The art is a solid 7 in my opinion, but the script is what hooks you. Nevertheless, there are some characters thatare underused, although they serve their purpose.
This half-fairy story, which would put Legolas on his knees, is highly recommended for those who love high fantasy, stories about vengeance, dark experiments, and underdogs. Hope you give it a try
