I have got one set of crystal ilbi, and the rest of stars are all ilbi. I notice that as long as there's one star in cilbi, my attack range will remain the same even if I am actually throwing ilbi. So in this case is one set of cilbi enough already?
Although I'm not absolutely sure as I don't have an NL, I believe I've seen @jmmainvi explain in another thread that this is a visual glitch and that your range, contrary to what you see, does drop.
Someone can correct me if I'm wrong, Im fairly sure that despite what your range may indicate, if you are using illbis as a opposed to cillbis, your damage will drop.
