Plvl at nachals?

[eqz]

I can't find the spot in the first floor where my friends can stand and xp while i'm killing nachals for them. Can anyone help tell me where it is. I tried the spot next to the rock, but it doesn't seem to be working.

I think either the tunnel to the secret room or the hallway between the 2 secret rooms. (2nd one works for sure but not 100% sure on the 1st one.)

Just get ur friend in the hallway next to the room.
