Welcome to the endgame, Captain. This is where the boys become men, and the ships become floating fortresses. The XP drops are massive, but so are the risks. Hope you brought insurance.
If you want fast XP, this is it. You're hunting Krakens in the Wilderness. The XP is insane, but you will get attacked by PKers.
Warning: Don't bring anything you aren't willing to lose. If a clan logs in on you, just accept your fate.
This is the peak of Sailing. You're setting off into the unknown to find randomly generated islands. You'll face storms, hunger, mutinies, and boss monsters.
But one successful voyage can net you a massive chunk of XP. It's not just training; it's an adventure. See you at the 99 party!
