These are no longer level 6-8 and are in a different location.
If you swim across the river SE of Howth, crossing to the east side right before it broadens into the lake, there is a grove of trees and a camp of these luricaduanes. They were all yellow at level 25, mostly blue with an occasional yellow at 26. Brannigan (one-time-drop mob) spawned there once, at night, while I was grinding there. These pop relatively quickly and are not too tough to kill, good XP camp IMO. Some of the things they drop now:
Silver Blade (2672)
Imbued Vest
Stoic Defender
Ring of Blades
