So I've realized I must have picked up an SSR weapon drop from Rahab sometime before having enough for the final limit break, what should I use my materials on? I'm 5 gold mats away from getting the final one from the store but I don't think I need it. Books may not be super helpful, as I only need 3 SSR books and all of my SSR kamihime are fully limit broken, and I all of my main element (wind) SR kamihime are already MLB, and I'm not desperate for Soul P as I just got D'Art.
