I know it, you know it, everyone knows it:
THE SHRINE OF STORMS IS BLACK PHANTOM TERRITORY
For a stunning lack of regular black phantoms (only one i can think of is Satsuki's dad), you see more here than anywhere
Some do appear in PBWT, but you get invaded all the time
I enter, and before i step 5 feet from the archstone i get invaded back stabbed, the fire stormed
Away around this is avoiding this place at PvP SL (120)
Post any other useful advice against black phantoms in this thread
Remember this: What you may know, may or may not be true; and what is true, you may or may not want to know.
