ksro lvl11 quest need some help

[YOK]

it says; go to the witch of the evening sun, left top of the map near lighthouse. tells me to kill 10 lvl11 mob called 마구간 보초 (Harness for sentry)...

ok i have found that mob west side of the map, in lvl1-4 mob area, with a symbol on their head. killed 10 of them and completed 1st part of the quest.

2nd part of the quest wants me to collect 5 quest item. killed many of those mobs no drops (and low xp than other lvl11 mob - bears).. so can any1 give me some advice abt it? ihave translated all the quest text but couldnt understand where to get that quest item.

tnx for answers
