"Everything About Collecting
Published by [Stoneheart]
this was lifted, from flyffworld. still, it's useful information. and the more who know, the better :]
the only thing i'd like to add is; in my experience, i've collected on average 1.5 lightning pieces per silver battery (10 days). out of about 8 silver batteries, i have only ONCE recieved no lightning (7%) pieces at all. very profitable, but only if you can leave your computer on for 10 days (not forgetting to relog at maintenance, or if you DC). overall - well worth it!
