Set camp on the hill south of graveyard (Wiz SF port spot).
Kill any dark blue mob around that graveyard which has that name:
a lava walker (Wyvern)
a mature wurm
a shadow drake
a soul devourer
a wandering wurm
a wurm spirit
Black Scar
Eldrig the Old
Faerie of Dismay
Guardian of Felia

Wait 40 seconds or so after death and see if a mob pops left of the rock which is at the bottom of the hill between hill and graveyard. If it does, you have the cycle under control. Keep killing that PH/Named. Profit.

Also, beware, there is one mob in this cycle which can summon.
