In Dark Souls, does the Darkmoon Blade Covenant Ring work from any PVP location? I've been wearing it for quite a while, but it only worked a few times while I was at Anor Londo.
The Darkmoon Blade covenant ring can summon you from outside of Anor Lando but cannot summon you from 'anywhere'. It can only summon your while you are in another 'pvp/coop' area. (any area where you can put down your white soap stone or use the blue orb)
Example: It can summon you while you are in New Londo Ruin, but not while you are at the Firelink Shrine.
