I've got 100 people impressed probably twice. It's quite rare to impress everyone because even if you don't make a single mistake, if you don't do things very fast, you'll lose a few fans. It can also take a while to get 100, and the more you keep trying that, the easier you'll mess up and get frustrated of the controls.Just keep trying, and eventually you'll do it. Maybe. Sometimes I just give up and forget about it. But getting the Moonstone and 10,000 Gil is still worth it, IMHO. And you can use Moonstone to enhance Eiko's Carbuncle summon. IIRC, Moonstone + Carbuncle casts Safe and Shell on everyone.
