1st you need to find the Offering. But if you look no one tells you what the offering is.
Its like a sick joke and then you find the item and you get the joke lol NOT.
You have to look around the Temple of Uggalepih until you find ??? well once you check this ??? mark you get an Item called
Offering to Uggalepih. Aint it so funny

.
Get it they tell you to get the offering and someone ask what is the offering so the answer the offering. Yeah some people have all the fun.
Anyway after getting the
Offering of Uggalepih <-- (People this is the item you need to spawn the NM its an ITEM). you need to find the
prelate key dropped by Tonberry Stabber. After this you find the room and trade the
Offering of Uggalepih your NM will pop. From what I read the NM will drop the Mitts every time.
I hope this helps others. The NM is lvl 75 Summoner so you need a strong party of 75 tank and 75 DD and others take 6 at least. Its not hard but not too easy so dont under estimate him.
Also it has a Rare drop of Light Spirit Scroll so you might want to fight him more than once GOOD GIL so bring a Thief for TH2.
GL to all Chao.
It was so annoying finding the info but it was obvious. But then again it wasnt if you didnt know that the Offering is an ITEM
Offering=
Offering of Uggalepih .
If any of you ask me how to get the Offering I laugh at you after this since you just dont get it.
