Do we have to get a dm for -any- PvP? What if we're all alone in a dark tunnel and I get oppurtunistic? EVen of there no NPC's, like a charctor hide out, etc...

Just wondering.

It is always recommended to try to get a DM for -any- PvP, just so we can worry about potential issues and not the players, and to ensure that everything is done fairly, etc.

However, in areas with no NPCs (such as dark tunnels, the Underdark, hideouts) it is not mandatory to have a DM observing before initiating PvP.
