Based on the 75 chapters I have read it is looking to be a solid novel set in a typical fantasy world. His cheat essentially pushes him towards killing weaker creatures as he needs quantity over quality. I can guess later on he will be getting the title goblin slayer from the public like the light novel it is referencing.
Amazing novel that weaves the world of Elden Ring and Harry Potter together. The fallout of a point of change in history is very well done and it's interesting to see where some familiar characters end up due to that change. Elden Ring's sorcery system is well translated over as the user has to "localize" the magic for use. Looking forward to see where this goes.
