Jeloc

Jeloc is hard, but not impossible with a bit of help. But before you go get it you need the following bosses first:

Deesis
Found at the very end of the Great Hall shrine. (need white pot to enter)
Cara Sa
Found at the left part of Hell Knight castle. (need 255 key to enter)
Equar
Found at the right part of Hell Knight castle. (need 255 key to enter)
Drennon Marr
Found in the Main DS. Keep going left then finally trans into his hall.
Slyth Kel
Found at the end of MC1
Roxthin
Found at the end of MC2
Ryzar
Found at 4th floor in Warlock Castle. (need leaf to enter)

Once you killed these you should have close or have full alignment. If not, kill one of them again (easiest is drennon) untill you do.
Once you are level 36, you can go through a the shrines. First you go get the +2 shrines, which are kinda similar in the way the regular shrines work (albeit these are certainly harder and you would most likely need help with some of them).
The last shrine (also reffered to as 6th) is a large maze, with lots of dropdown walls. It can take 30 to 60 minutes to complete this and is very hard. Its best to ask people higher level then you to help, as it is practically impossible to do this on your own at 36.

Upon completion you should have +7 to all stats and a nice background to your name. You can also talk to Corsix for an extra 3m xp.
