Small Trick ,Two different char to run in same game

Sometimes, we need two different character to finish the task and you cant find anyone else to help you every now and then...

Then you can do this,
A Create game,do something, A quit
Switch to B, type room name, join back, game still remain it is...

In my case,
it is rush lazrok, A3 scenario, I dont want to play through organ collection.
My A is Lv 93 sorc open in normal, port to a3 last portal, kill all the way back to trav, exit game, My B join back by type game name(game will not disappear within several minutes), portal to trav,
walk to final portal. Exit game.

Then B can start game and directly go kill mephesito.

This can help people only use 1 account. It also work on different act...
