i think you could have a lot of fun with a build focused on Eldritch Knight, because i built one to get as many cleaves as possible and it was fun! i haven't done warforged or fighter that much but here's something. usually i try to get wizard level 7 asap because it's death aura, you might want to delay the 2 fighter levels after that so you can get to wizard level 11 for reconstruct, but you won't be able to get IC: slash at 12, hard to say. good luck!
