Just took down Linlanik and got a different drop than the one listed here.
Eyepatch of Pestilence 6 AC, 5 agility, 20 hit points, 20 mana, 12 save vs disease and poison. Has 3 charges of Counteract Disease (1 second cast time)
To say the least, he has a lot of hit points. I barely managed to solo him with my level 55 beastlord, ending off the fight being a pet cleric. Even with slow, Linlanik hits fast, doubling for a max of 140 points.
Also, the guys in the caves where Linlanik spawns give no discerable xp that I could see. Killed 3 mobs total to get to this guy, starting a smidge before the 2 percent xp line. After those 3 kills and Linlanik himself, I was ... a smidge before the 2 percent xp line. /shrug
Neat place though. Wouldn't want to live there, but had fun visiting.
I got him to spawn in dulak's harbor, inside the luggald caves, at: p2675, p25, p205. it's the second corner just before you go through the opening to the waterfall area. there's a blackblooded nightmare as a ph. respawn is 20 minutes on the nose.
i have no clue if he can spawn in other spots but this is the place that matches his picture and it is where i killed him tonight.
