Mano does drop the Rainbow Snail Shell, it's just a rare drop. But even then, you can't complete the quest with Pia. And the quest glitch is different for different classes.
no its not that.. he was a rogue and i was also a rogue.. he wasnt able to do the trainer quest that you get once you job advance.. but i was able to..
Sometimes quests stop/start working after a server restart too, hence why you could complete it and your friend could not. I know myself I couldn't complete 2 quests in Kerning on my Cleric, and they were specifically activating the quest glitch. After a week or so they suddenly worked out just fine.
