Antique Bead For The Passage Not Appearing?

Hello!

When I do The Passage quest with a friend, he is the only person to obtain the bead. I later do The Passage with another friend and he lets me get the bead, but I cannot pick up the bead and my inventory wasn't full. Does this have to do with the last person to hit the boss? Please help!

 

Unless you do 15% or more of the damage to a boss, you won't be able to pick up its drops.

 

You need to do more than 15% of the bosses help to get the drop
Basically you don't do much damagge :p

 

Okay! Thanks!
