The ultimate sword mod adds... well the ultimate sword + stuff needed to craft it. I would recommend getting the Just enough items mod to find out how to craft the ultimate sword. Anyways you can get a sword outline from a tool smith and a weaponsmith. Rainbow powder is crafted by combining 9 different colors in a crafting table. Ultimate ingots are made by 1x copper 1x iron 1x gold and 6x rainbow powder. I really don't feel like explaining it all so just get the just enough items ok?
