I got a coordinates clue and it said i had to go back to crandor but when i tried to get back on the boat klarense said its his new boat and will not let me on how do i get back to crandor?

Go through the "odd looking wall" in the karamja volcano.

But i thought i could only go that way if i went through it the first time i telleported instead

Oof... I don't think you can get back then if you didn't leave through the wall.

Thnx for the help but it let me through the door
