I noticed that it makes a differece in the passives of a LI if you put Star-lit Crystals on it before or after imbuing.
Since I found no official statement about it and nothing that inform you about that circumstance I guess its a bug. Or at least I hope its a bug which gets fixed someday. Not that it makes a big difference but I'd like to see my twohanded sword completely maxed out.
Any info if this is WAI or a bug?
