I killed liked 12 of these with a lvl 51rdm/15thf and not a single thing was dropped, let alone the damn lens I was trying to get. Then I went out to beauceadine to try and kill some bat eyes killed 2 they didn't drop anything and almost killed me. So I gave up, went to the jeuno ah to just buy a lens and I couldn't find it listed anywhere.... WTF? Any info would be greatly appreciated.
Oh you'd probably hate me...but I got a Lens after only 2 Floating Eyes. Lvl 50 Thf/Nin Though I also had help from a Rdm and Drg as well. Was on our way to Eldieme for my paper, so killed a few along the way. Though I still need one more.
Just to clear any misconceptions about the drop rate, yes these guys DO drop the Lens. I just got one in the Pass, but I had to kill 24 of them as a WAR/THF to get it. I imagine much like the Carb Ruby, the higher the level of the mob, the higher the drop rate.
These things cast spells up to Aero II. BLM job, but hit hard as well. They cast petrify as well, so if you're gonna solo, shock + silence... or have MASSIVE mnd.
