First off, id like to say that this is heavy xp, Avarege completed xp (Not included mobs) is 18k xp.

Second off, id like to say that im an undead warlock, so this is writtin for the hordes.

First You have to go uptairs in the house located at around (37,55) in the Westen plaguelands. You meet a ghost woman (Janice Felstone).

She gives you a quest, which is simply, go inside the house/barn next to the house, and take the packet on the floor, TWICE!

Take the packet to Uc, were you have to talk to the guy whom stands next to the guild creation npc.

He tells you that the man you seek is a vendor in Uc, he is found under the stairs at the bank (Think hes marked on your minimap)

After talking to the vendor, you recieve a piece of an amulet(lucky charm), Bring this piece to the Ghost from before,

After doing this, you have to go outside and kill the Jabbering Ghoul, he drops the second piece.

After killing him and getting the piece, combine them (simply use the item) then talk to the ghost a last time.

If i remember it all right, you should now have over 18k xp earned in about 20-40 mins (depends on lvl)

I am a lvl 53 undead warlock, and i did it in about 20mins.

The listing here is a little messed up. Here's how it really works:

Get this quest from the woman on the second floor of the inn (the northern building.

Once you have the quest, go into the stables (the southern building). Click on the package turn it in.

Now click on the package a second time. This time, you'll get the quest to go to the undercity.
