on the quest guide, it says:
Level 34 - Leegeuk's Jewel
NPC: Donwhang: Leegeuk(specialities shops)
Objective: Kill Robbers to obtain 200 "Juwel of Leegeuk"
Reward: Reward: 250000 gold

is that robber or robber follower? because robbers are lvl38 mobs and this is a lvl34 quest...

you can get the drops from followers

I'm not sure if this is the quest I'm thinking of... but you should be able to get the drops from any of the bandit monsters: archers bowmen, followers, bandits.
