Sebak  

Best place to find him is infront of Fortress of Storms. He has a route that he takes but if you wait long enough he always go into that fortress. He has about 10 adds with him oj's. Way i duo him is i pull with healer and peel 1 add with thane. Kill it Sebak loses agro walks back to FoS. Repeat. No adds then i drop a heal font and tank sebak using taunt styles while i move the thane into the font range. Takes a while to kill and Dmg add helps alot. Annoying thing about him is fight is so long he will lose agro and you gotta build it up again. Ive killed him about 4x like this always dropped robe and a crapload of unique all type of weapons.
