When you reach your high 40s, instead, go to Tanaris and the Dune Maul Compound to grind your last couple of levels (talk to Andi Lynn in Gadgetzan before you go to pick up a great kill quest for your trouble), or go to Felwood or Un’Goro if you’re looking for more quest experience and want Tibia Gold something different to try.
Don’t try Felwood or Un’Goro until at least 48, but do plan on going there, especially Un’Goro as it’s a fun area, lots of quests and very big dinosaurs.
You can start the Pterrordax kill quest that you get from Spraggle Frock (yes that’s really his name) for Un’Goro crater at 46-48, but you’ll need to level in there to at least 48-50 to finish it, more than likely. Watch out for Devilsaurs, they’ll kill you very quickly at this level.
On the other hand, you can get a quest from the fur-bolg by the entrance of the tunnel and go kill Deadwood fur-bolgs to get your faction up, gain decent xp and loot mage weave.
Not a lot of fun, but it isn’t necessary to get their level any higher than that (provided you don’t kill any), so it’ll be over pretty soon.
