Yea so I'm one of those guys that goes like 0/bazillion on all rare drops, so I get a little annoyed at stories like ChiTown's. But anyway, for anyone interested in the drop rate, I'm currently at something like 0/40 to 0/45.
I was doing it as a Solo MNK, but the cost VS success rate was just too demanding. Now I go with a WHM partner.
Enter, Boost X10, Use an Icarus Wing, Eat some food.
@ boost #10, move towards the Red Receptacle, and 3 others will spawn. Look at the two blue ones, find the one that's less blue and then Chi-Blast it. Attack it, run in and Raging Fists. It usually takes one more attack round after this to finish it, so this is a convenient time to use a High Potion. This is the only time I use one.
Once that one dies, (Note, /autotarget off) the NM Contemplator will spawn. Use a Psychoanima on it, and then attack the Red Receptacle.
At this point, you have 20ish seconds before the Contemplator will start attacking you.
Have your WHM Divine Seal, Repose it.
Your WHM will be getting drawn in, and Empty Seed spam will hit him/her too, but all the WHM has to do is stay alive, toss out an occasional cure, and be ready with benediction should anything go bad.
At this point, Contemplator is slept, and the MNK will Focus > Dodge > Berserk > Hundredfists. Spam Raging Fists whenever possible, and hit Chakra when you get a free second.
After a few practices, this should be 98% win, with an occasional ***** up that can cause a loss. An example would be, More than Usual Empty Seed Spam, forgot Icarus Wing, forgot WAR sub, etc...
Lastly, the MNK should sub WAR, and wear as much DD gear as possible, you arent going to evade Empty Seed, and the Contemplator won't ever hit you if done correctly, so the idea is just DD.
All that being said, good luck, I hope you get a better drop rate than I've had so far.
