So I had been looking for a piece of armour with a certain property to avoid using relic fragments. I found an item (studded hiro sode) with the properties I wanted and in haste I imbued the other properties I wanted before I realized it needed to be altered. Once I realized my oversight I tried to alter and of course got "you may not alter this item". No big deal it was my fault and the ingredients I lost won't take long to recover. I've looked around and can't seem to find a list of what's alterable and what's not and I was just wondering if a list is out there. Also I'm not really sure why more items aren't alterable, why are leather sleeves alterable and a studded hiro sode is not? Anyway is there a list of what is alterable and what isn't?
