Soloed two of these with my averagely equipped 65 beastlord. Spotted one just around the first corner, couldn't see around it to tell if there was another one waiting around the next corner. Sent the pet in, sure enough, there was. Slowed both after pet had decent aggro. Dotted them with Plague, stepped in and out as hp and mana required. Began the fight with full mana and hit points, ended with about 20% mana, 80% hit points. Both conned dark blue. Did not summon, but they did have a damage shield I had to dispell. Did not see any wanderers, so suspect that these are not rogue mobs as stated. Then again, I didn't give them a chance to backstab me either. Decent enough exp for 65, but not as effecient as the basement. Same loot drops. Diamonds of all types, parchments, runes and torn pages. Unlike the basement mobs, these and the geonid type mobs had some cash loot, around less than 1 pp to 9pp and some change.
