Combat not prohibited
It's not that combat is prohibited in Sanctuary areas – in particular, there are several quests that involve fighting or killing a mob or mobs in the Lower City in Shattrath. It's that PvP combat is prohibited. I don't even think you can set your PvP flag in these areas. Page has been updated to reflect this.--Scrotch 00:25, 2 March 2008 (UTC)
You can PvP flag in Shattrath, and obviously PvP servers, you'd be flagged anyway - but the PvP combat prohibition remains, obviously. --Joshmaul 03:32, 9 April 2008 (UTC)
Do the guards attack you if you try and engage in PvP combat, or can you not do it at all?
