Ok, Shak Dratha Shadowlord is one nasty little dude. Hit my well buffed 26 necro for 60-80 a whack, often 3 or 4 hits at a time. He resisted all attempts at dots, only spell I found that would touch him is siphon life and of course feedback from banshee aura. Estimate somewhere in excess of 1200 health, (counted up 1055 from the log, plus whatever my pet did to him) Only damage shield and Temperance saved me. 15? I think not. He did drop a faded salil's writ page and some xakra kel pants.
