Was solo hunting RSE in Maze, accidentily popped it, not knowing..."The hair on the back of your neck stands up!" This thing just starts wailing on me(additional effect: slow). After one hit from it, I could see this fight wasn't going to last too long, so I blazed it up with Counterstance / Berserk / Focus / Hundred Fists. Dropped the Sachet. Good thing Chakra removes poison; it was a really close fight. For the record, I keep Four-Leaf Mandy Bud, Wild Rarab Tail, Carbuncle Ruby, and Meteorite on my person.. call me crazy.
I have one of these. Get it by beating an "Aroma" mob spawned from one of 3 ???'s in the approriate RSE area during RSE time. It is not a 100% drop, I had to beat 2 aroma flies to get it. Respawn on the ??? seems short, maybe 10 minutes.
Nice thread that helped me get it on KI, with links to maps on the locations of the 3 ???'s in each of the 3 RSE dungeons.
No it is 10 mins, its just random at which of the three locations it will appear and if you don't find it with in the 10 it changes locations. the fight isn't too hard but for a lvl 50 it may be pushing it, i took it out with my 66mnk and it hardly touched me. not a 100% drop took me 3 trys before i got mine
