Just open Void portal and...

what to do here(its like a tiny island with no way out, just the chaos sanctuary portal)?! only a golden chest and some mob i killed before i can see what was...

Re-run Diablo until you get the right map. For other short questions, feel free to use the short questions thread.

for some reason i get the map correct everytime if i summon it on bottom of the chaos sanctuary. bottom = where lightning harpies spawned. dunno if im just lucky asf or is there something else to it

Try changing difficulties and then reroll to dest difficulty. That map is just for farming crystals iirc

well i tried a lot to re run and reroll and still does the same
help plz i can't finish this one

It's a 50% chance to get the right map, just re make your game, no need to switch difficulties or anything, keep it on destruction and eventually you will be getting the right map.

I've opened the portal like 5 or 6 times and i've never seen the troll/wrong layout. Lucky me ?

I dont get it. Ive killed diablo 10 times, and all i get is this island. What is right layout?

I don't think it is about rerolling the map or maybe this map can't be rerolled
i guess it is about the character it self , by the creation of the character the map cannot be changed

On multiplayer just keep trying.
On single player after each island map, go to a terror game then back to destruction to try again.
Keep trying it'll work
