Is hereo battle implemented yet?

I could not find it anywhere on the Battle Isle map and have tried talking to different npcs on the islands but they do not say anything about heroes battle. I've tried asking around in-game, no one knows anything about it. I could not find it on nightfall's game manuscript and Wiki is slow. So I was wondering where I can do hero battles against real people. Is this even implemented yet?

I made a new pvp character, talked the priest of balthazar in the temple of balthazar and he took me there. Think you have to have atleast three heroes unlocked already.

Have all but 3 heroes unlocked. The priest doesnt say anything about hero battles

It has something to do with completing the basic Zaishen training, or get access to Zaishen Elite. If you do both of those, return to a Priest of Balthazar and he'll give you some heroes.

You also have to own Nightfall :P

Well I don't know what you're doing wrong; but here's this if you don't believe me

thanks for the pic. I have completed the Zaishen training and have access to Zaishen Elite long before NF. But ill give it a go again.

Well I didn't do zaishen training or anything; just made a new pvp character and talked to the priest.
