Velanthra

Velantha is the evil side equilevant of Jeloc. As with Jeloc you will first need some bosses killed before you can start getting it. These bosses are:

Renn
T1/T3/T7. Ask goodsiders to help you with fireballs.
Arnius
Lonya

General Veerseloth
T3 Castle. Ask goodsiders to help you with skelliewall.
Cara Sa
Left side of Hell Knight Castle. (need 255 key)
Equar
Right side of Hell Knight Castle. (need 255 key)
Dirnok
Do not kill him, just talk with him

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 HK King for an extra 3m xp.
