I did not play the EA much, never got more than level 3, but decided now to give the "new" build a try.
Could you as trained players give a rough advice when to go where with what?
My group is still level 3 far away from uplevel, relatively badly equipped (what I found); I did the skeleton, orange quest, the turtles, Gavin's crocodiles, the nasty frogs, the Arena and some smaller stuff. Is there more on the surface? Griff and his villains and all magisters are still alive.
Recently I got into the prison under the Fort Joy through the statue. Where I killed the first four magisters and their dog near the wounded magister guy, unfortunately with one casualty on my side. Then I ran out of lockpicks (didn't know they are one-use, stupid, isn't it?

). Back to buy some.
And now? Is it too early to explore Fort Joy main floor? Did I miss considerable xp out of it? I'm often quite lost to find quests. There were presumably similar threads earlier in the EA, if so, do you have a link?
