In Crystal Caverns: Warrior; has ~1,800 hitpoints.
In Crystal Caverns, Fragment of Fear: Known to spawn at 470, 500, -373 (west side of the bridge that's just above the Ry`Gorr pit bottom). PH is "a Ry`Gorr excavator".
Ok went to camp this named and his bridge PH wasn't there. However - after tracking down and killing the "a Ry`Gorr excavator" elsewhere in the zone, he then repopped on the bridge.
Whereas the map that someone has posted on here is useful, the easy way to explain his spawn point is fall to the bottom of the pit by the zone in (with levitate). He spawns on the first ice bridge off of the bottom
