Level continuation 43-60?

[Drizzit]

There is a quest at that place just before entering western plaguelands that talks about some cauldrons.. it is the easiest quest yet brings in around 40k xp in a matter of 30mins.

I believe that you can only get the cauldrons quests starting at lvl 50.

If you are 43 now i would go to zf and grab the quest there. There are about 4 pick up quests that has no chains (3 in the town and 1 in the shimmering flats). 1 run should get you like 6 bars (don't forget to get the 10% bonus by dancing at the pole out of the town). The quests should at least get you a half a lvl. So just running zf once will get you about a lvl in an hour (that is how long it takes my rogue to do it).

Oh i forgot the quest in shimmering flats you need a hammer to summon the boss for the drop. To get the hammer is a little quest line, kill a mob in hinterlands (100% drop, not a quest but a drop). Take the hammer to a tower in Hinterlands to "charge" it, and then you have done.
