He hit up to 500, flurries, runs at 15%. Once I got him slowed with Truncheon of Doom he was much more manageable. 58 war with merc took him. Dropped Left Eye, Sunshard Ore and Secret Letter.
I am not sure if this was a glitch, but I saw him up in three places at the same time. He was at the top of the far tunnel in the zone, in the the middle spot where the three spawn in front of the temple like place in the far and of the zone, and in the temple if you are facing the back, to the left of the lava pit. He dropped the jeweled sceptre of the heavens two times.
3 of us, 58 dru, 66 paladin, 70 bard were hunting in DN for the cultural armor quest when I picked this up on assist. Whoa guys that's a named red!! Dots landed no problem and snare was resisted only once. I only had to heal the bard and pally once each which wasn't really necessary. It seemed to have about double the hp of the other mice and may have enraged towards the end. It dropped the two items listed above. Much easier than I anticipated but I was with 2 skilled players and we worked well as a team.
Spawns in many places in the zone. I just killed all rats behind the waterfall near zland since its the safest place to kill at. He spawned in the place of the rat closest to Zland. Snareable, summons, doesnt hit too hard. easily soloed by 65 necro with EP gear.
I also camped him at Zland's lair. He was a very rare spawn. I actually camped him for 2 or 3 days in 4 or 5 hour camps before he finally spawned. Dropped the items the first time. I took a screenshot of him and sent it in which is posted above. He really does exist. Was easily duoable by a 66 Druid and 67 paladin.
Found him outside the tunnels last night, very first rat we killed, group of cle + monk =2box, war + sham =2box and druid all 62+. Took less then a minute...
I'm not sure how randomly he spawns or if it's one set PH, but I spawned him right outside Zland's lair. That is, heading to Zland's lair, I swam past the pool, through the waterfall, and the ph was the second mob over on the right wall. Just camp there and you're bound to pop him; I'd go ahead and clear the whole lair to kill time and perhaps see if he spawns elsewhere.
