Not to be picky but in game we dont have Blacksmith Shadai here on the server and you didn't tell us how to actually get Magnificent (in game its called Glorious) brooch / Rare Magnificent (Glorious).
Via Alt + B we can upgrade to 5 slot brooch, then use Compound 2x 5 slot => 6 slot
(what is the success chance?)
And then I guess we can Compound to Glorious brooch? Success chance?
2x Glorious again compound for Rare Glorious? Success chance?
