Blue Mage's Testimony  

In a little narrow way North of H-11 in Wajaom Woodlands, there is a Mimicker and a raptor. Easiest place to camp the monster. They respawn exactly five minutes from their deaths, as opposed to the monsters in Mamook which take fifteen minutes to respawn. Also, if things get hairy, you can quickly zone to the Subterrain area to the West of the camp.

I helped a buddy of mine get one off of a Mamool Ja Mimicker in Wajaom Woodlands. At D-9 there's a zone guarded by 4 Mamool, a Bouncer(Thf?) a Sophist(Blm), one which I forget the name of (whm, and the Mimicker(blu). The thf and blm are near one and other and the zone, so they're in the way. What I did is pull both w/ Poisonga and zone them to make them despawn. Then quickly zone back in and pull the blu w/ silence. That part is a bit sketchy as the whm is relatively close to the blu, but if you've ever pulled beetles or other sight based mobs you should know how to do this (make sure the whm is facing away when you pull it). There is plenty of room in the cave to sleep nuke without being near the thf and blm. My friend was 67blu and he timed frost breath to go with my nuke, which seemed to be working nicely. He tried to sleep with Pinecomb Bomb but it didn't last very long (but oddly enough can not be overwritten with SleepII). Took 2-3 Mimickers but we got the test... just thought I'd let you all know. I'm sure there are other Mimickers but this one was nice, it was easy (coned T to me at 70) and near the city. Hope it helps.
