DnD System in Dc

This fanfic it's very important for me, i started thinking abt it like 2 years ago, anyway just wanted to say a couple of things, 1st, this fanfic its a: Dc universe/Lucifer(TV series)/Sandman(netflix series season 1) Transylvania(some parts of it, Heavily AU)/Castlevania/ Chilling Adventures of Sabrinas/Percy Jackson Universe/ Forgotten Realms(DnD and Bg3) mix, all in all it is heavily AU and it will not be people just punching each other in the face, it'll also have a bit of kingdom building(be warned),  2nd, the protagonist is Polyamorous, So harem(NO ntr of any type, yes to some Yuri during threesomes), the love interests won't be more than 4(more only if we arrive at some crazy number of power stones lol, like 50 or smt total power stones), the relationships won't be rushed, and they will be relationships, with people, they won't be fucktoys to be discarded after(insert new girl appearing), they will have their gripes thoughts and emotions recurring in the story 3rd the protagonist has a character arc, he won't be a mary sue and while in certain situations over powered, in all these universes there are A LOT of people that can kick his ass off to Sunday, he won't be winning every fight,  also his powers grow first horizontally then vertically(essentially using the powers he has creatively before unlocking any new ones, the vertical growth of his powers will be very slow. His power level is about City level (i basically made him a slightly stronger Homelander + plus some haxs like the Sukuna-like slash and his reality rewriting that his basically a weaker Allmighty at full potential but is HEAVILY limited and has a lot of backlash), those powers have more potential than that but he has to discover them, grow them and it happens slowly, the priority is the story, not how-do-i-make-an-op-character-in-less-than-thirty-chapters, the Love interests are: Sally Jackson(image) Zatanna(image) Raven(image) and a fourth that i want you guys to vote on (chapter 7)
