I'm wondering this because I recently found out how to dupe and I've been duping my rarest units. I'm wondering if it affects my drop rates because I went into V-hard caves, found a Nar Lily, killed it and all I got was 2134 Meseta instead of HP/Revival. (87.5% chance of HP/Revival). Since not getting the item is very unprobable, I was wondering if I should keep my duped items.

no, most people on here make back ups {so if there game freezes you have all your rares} if you dont trade them i think itll be okay and no it doesnt affect your drop rate
Oh ok.
I'm trading my friend copies of all my items for copies of all of his. I was just making sure that if my game was messed up from the dupes, that his wouldn't be.
Thank you for your help.
why would u do that? the fun is gettin the rares man

weird first time i heard of dupe trading for same items how odd lol =)
I always thought the fun was in killing everything in sight.
Plus my friend and I are very strange when it comes to PSO.
I'd hate to burst your bubble, but trading dupes is pretty much illegit...

Oh well, nothing we can do about that though.
How is trading dupes for other dupes illegit?
i dont dupe my items i find them fair and square
Because its almost like cheating. You can keep dupes as back-ups if you get FSOD, But then you could dupes as many items as you want and trade them with other ppl continuously just to get other rares. So dupingfor trading and giving away is illegit.
EDIT: BTW Vicous, you're not allowed to double post. plz don't do it again.
