Where i can get Experience?

I know Cowlevel and Baal runs, but i forget, how to open Viper's lair. I was on this server 3-4 months ago and we get exp in Viper's lair (i forget original name of this dungeon). Is it on this server yet? Or it goes off?

 

There is no Viper's Lair in this patch, as far as I know. You probably played some modded patch (with different modifications that the one on EuropeBattleNet).
The only area that resembles, by name, in the official patch, would be the Claw Viper Temple 1 & 2, found in act 2, after Lost City.

 

And for most xp, you should try main 85 lvl areas, including bosses, in a private 8-player game with main char killing around an the other 7 in town. No other better recipe, at least to my knowledge.

 

diablo and baalruns I find to give most xp

 

Agree, but only if there is a quick tele - kill party.

 

I believe this is not allowed, you are allowed to have only one char in a game, exception make the trade games!

 

nu stiu cine ti-a zis tampenia aia dar cred ca-i o aberatie.. e cel mai bun mod de a face xp : 7 pici in orash si tu solo wsk + baal si diablo.

 

You are allowed to have 8 characters in the same game, But you may NOT have more than one private game active.
