The idea of this build is to have Black Phantoms do the dirty work for you while you sit back and watch the fight. 8/10 the invader won't notice the BP is hostile until it's too late. Those that notice have a hard time keeping track of both the host and the invader and eventually slip up.
Requires being Gravelorded and spawning Black Phantom Berenike Knight in Undead Parish. Low level is to lure Invaders. Ninja ring is to avoid being killed by your Charmed Black Phantom (if you charm an enemy mid-attack animation, it will still attack you. Be wary of the long range of the Berenike knights).
Channeler's Trident will be kept in inventory until used to buff black Phantoms. Alluring skull is to safely charm phantoms from behind.
