Make cave worm pvp free?

[Ingot]

Can anyone tell me exactly how to make the cave worm a pvp free room without also disabling combat on the caveworm?
The attributes field set to 1 will make it pvp free, but it will also disable combat on the cave worm.

I can't think of a way really.

My only thought was make it a arena, but that wont stop pvp just protect against eps,death pile raiding. But could make the death room the same room...they would kill over and over with no real effects. Maybe slow down the exp.

That's an interesting approach.
I wish there was a list of all the attributes that can be applied to a room. I bet there is a combination that would accomplish this.

If you click the ? next to the attributes in the room editor it will show what the guy knew at the time it was built. Now if people did any more testing after that I'm not sure.
