PvP Arena with Spectate? (No PvP area)

[Yuka]

Hello,

 

I am working on a PvP Arena with an area for spectating.

But for this I need to make a specific area on the map nopvp.

setcell "prontera",100,100,150,150,cell_basilica,1;
setcell "prontera",100,100,150,150,cell_landprotector,1;

This crashes my server when I pvp at the same map and move in/out the area.

 

If this isn't possible by setcell, is there some sc effect that cannot be canceled by the players and prevents them from attacking/ using skills?

 

Would be pretty cool if there was a way to do it!
