How do you get to the battle tower? I have beaten Amdusias and returned Lovis' soul stone. If I swim toward the tower from Orobas Fjords, I run into an invisible barrier that won't let me pass.
Have you gone to sentinel island and defeated Laiken to take dragon form yet? If not, you need to go back to Maxos temple and in the chamber with the crypt waypoint shrine take the right side passage, you will fight a short battle with some black ring and have an encounter with a character. After this, there will be a teleporter to take you to sentinel island. There you have to complete a bunch of quests and take the battle tower. You can't swim there from orobas
Now if you have taken the battle tower, just use the dragon stone to return.
