WOW PowerLeveling: Keep heading west from where you unloaded to the other end of the island
Make your way south to the bank in Draynor Village. Withdraw some armor and food to kill a level 120 Black Knight Titan (you’ll have to wield Excalibur in order to battle with the titan). If necessary, also get a full vial of anti-poison potion in case you get WOW PowerLeveling stung on Karamja.
Now that you’ve got your necessary items, head west and take the ship in Port Sarim to Karamja (requires 30gps). Keep heading west from where you unloaded to the other end of the island (past the town of Brim-haven).
From there, you should see several level 20 poison scorpions. They aren’t aggressive, so they won’t attack you if your combat level outmatches theirs.
Keep going north past the gold ore rocks. You should see four pillars on the outstretch of land to the north. Go under it and blow on your Magic whistle. You will be teleported to a swampy area.
To the northwest of you is the Black Knight Titan guarding the bridge? You’ll have to kill it in order to gain entrance across it. Once it perishes, head across the bridge to the west side immediately.
