Okay, some of the Celestial Weapon side-quests suck, like Lulu's. I find it much easier and more beneficial to build my own super weapons for people rather than try some insane side-quest for a weapon that has some abilities that I don't need.
Granted it technically should be easier to do the sidequests rather than get enough of the rare items to add an ability, but I find it easier and less frustrating to just build 'em myself.
Screw Caldabog, I'll make my own weapon that's much better.
