I completed a run of the Slavers, and received Legendary Shackles, Legendary Five Rings, and Legendary Chains.
I did all the optionals and chests, and received 4 Legendary Broken Shackles. It takes 400 of them to make one Slaver Gem, and each of these items can hold five gems.
Do I have to run this quest 1500 times to complete my items?
What did I miss?
