Finally got the eye from Hellion after 5 long hrs yest So a word of caution, if you guys wanna go for the 2rd part of the quest to get the eye, be prepared to die a lot of times. My lv 91 bksmith died more than 15 times even in a big party of 10. But i saw a party of 4 manage to killed Hellion twice, 1 tanking vit knight, 1 ds hunter with superior dex that hit 3.5-4k each shot and 2 priests.

Btw if you got the Nile Rose, you cant do the Gefennia 2rd part of the quest.
