HELP, Thunderhead Keep

Can someone please help me with this mission, the clearing of the city and fort are no problem. Even holding the fort isnt a problem UNTIL the boss comes, how do you beat him?! The first time and second time i tried he had a healer with him so i killed him first, the third time he had an elementalist with him and i killed him first no prob. But he just wouldnt die, i got him down to half his health but then jade reinforcements arrived and my party died, ive failed this way with people and with henchman. Can someone please explain how to kill him.

Which boss are you talking about?


Spoiler--------------------------------------------------

Dorian? We had no problem with him, my elementalist killed him in like 3 hits =/

Like Eclair said, Dorian is actually rather wimpy compared with the mursaat and jade bows that come in droves before him.

I dont think he is talking about dorian because that is the last guy you kill there are no reinforcements after him. Must have been one of the mursat healers which do infact take along time to kill. With henches at Ring of Fire took me like 5-8 minutes of fighting just to kill one.

There is a boss Jade that comes in and is lvl 28. He really wasnt that hard except for having troll ungent(from what i remember) could have been another healing spell, i know he was not a monk. Took our group about 20 seconds to kill him. To me the mission really isnt that difficult, just long.

thxs for replies, ive finished it now and realised my mistake i wasnt on about last boss, but one before- perfected armour
