I've spent a while tracking in LOIO and finally understand this guy's spawn cycles. What people have posted below is mostly accurate but not the full picture. There are indeed 4 PHs north of the windmill area. But if you kill the mobs other people listed you won't always have 4 of them up at a time.
The missing info is that there are some mobs that are ALWAYS a PH (group 1) and other mobs that are sometimes a PH (group 2). You will know if you killed a PH because another mob in the cycle will spawn immediately.
I haven't tested this for the 1 PH the roams between west of windmill and fort, but assuming it's the same.
Group 1 -- Always a PH -- Kill these first
a goblin brawler
a goblin skirmisher
a sabertooth cat
a sarnak flunkie
a sarnak youth
an iksar brigand
an iksar marauder
greater skeleton
greater scalebone
Group 2 -- Sometimes a PH -- Kill these last or when convenient
a goblin aggressor
a goblin battlemaster
a sabertooth tigress
a sarnak conscript
an iksar manslayer
lesser charbone skeleton
