How to get to Jade Arena

I have been to most of the Archipelagos, and walking back and forth from Cavalon, but just couldn't find where it located. Do you start from Cavalon or Breaker Hollow or Jade flats (I have been to all 3 outposts)? A specific direction or even a map with red path will be really appreciated. Thanks and forgive the NOOB(DUMB) question.

You can start from either Breaker Hollow or Jade Flats. If you leave from Breaker Hollow, take the east exit (the one with the supply line quest). There are two entrances from here. You can fight the first group (or run by them I guess) and there is a path in the land that will take you through some Oni's and on to the arena. Or you can stay in the Jade Sea type area, past the second group (the one near where the Kurzicks spawn when the supply line is active), and hug the right bank. Once you break aggro from the group, you will be at the Jade Arena on your right . Just run down the hill. The quest giver is back up the hill, but you will fight the guys down in the pit.

Thanks, Can you point to me where exactly it is in the MAP (A, B or C).

It's that area in between A & B....the area with all of the Luxon Arena Fans, and the Arena Master is at the top of a hill.

Yeah, if you're looking for a marker that says "Jade Arena" - you'll be looking for a long time. Just look for the fans and the orange / yellow colored poles or whatever. It's not a marked area - it's like a bowl type landscape - part of the "Jade Sea" as opposed to the dirt or grassy areas.

The first entrance I described above (in first post) is located probably at the middle-top of your 'A' marker. That is the one where you encounter only the first small mob of 3 or 4 and enter the grassy area where the Oni's pop up.

To get to the second entrance I mentioned, you have to get past the second mob and look to your right for the Orange / Yellow post things.

Thanks a lot, I found it.
