One that can be used on lower levels, preferably around 30. Can dupe all of my lvl 61's inventory which includes fire, shock, and corrosive infinities. Also 94% sham, bee, bunch of pearls and 3 types of o-negatives --- GAMERTAG:SpankedEagle
Are you talking about the Moxxi's Endowment relic? I have a level 13 one that boosts experience by 4.2%. I'm not sure if that's the one you're looking for, though; there might be other relics that give extra experience, but I haven't seen any yet.
Actually, if you can wait about an hour or so, I can get you a level 30 relic. I'm just shooting down Volcanic Rakks at the Vault of the Warrior to level one of my characters to 50. He's level 24 now, so it shouldn't take too much longer to get to 30 and do the quest for Moxxi's Endowment.
Bleh. The relic I got is only 4.6% experience boost. Not exactly a huge upgrade from the 4.2% I had. Still, if that's good enough for you, I'd be happy to trade it. Even if it isn't, though, I'd really like to have a Bee shield if you can spare the time to dupe one. It's fine if you don't, of course.
