Review Detail of Slesk in Harry Potter and the Rise of the Protector

This fanfiction feels extremely familiar to a fiction I've read before. Not exactly the same but it uses a lot of stuff from other works I've previously read. The Magical Core concept of cores being "leveled up" in the same manner as the states of matter "gas to liquid to solid" I've read before elsewhere. The concept of "MC is a kid so hires some downtrodden people and uses wealth acquired to form an organization that leads muggleborns and maybe magical races is also pretty much ripped from that previous work. I just wish I remembered the name of that other fiction. Anyways I'm not sure if this guy jus ripped off that previous work I mentioned or he is the author of the work I previously read and just re-wrote the whole thing. It just feels like this is too much of a copy of something I've already read.
