I love playing THK. I normally play with PUGs with my monk, (always a different mission playing with Pugs

) but sometimes I get low on gold and hench it with my W/Mo. You can get some pretty good drops here. I've gotten several sup vigors and many many gold weapons. I always take at least 3 shiverpeak keys, since there's usually around 4 chests in this mission.
I've recently henched this with my blood degen Necro, so I suppose you could probably hench this with any profession without much of a problem.
Here's my strategy: As a W/Mo I would get one fighter hench and
both healers, the mage, the enchanter, the cultist and the
archer.Playing as a Necro, I replaced myself as the necro(cultist)
and took both fighters. I believe, as long as you have 2 fighters
and 2 healers along with the other henches you'll do ok (you could
probably do fine as a warrior taking 2 fighter and leave out the
enchanter or mage).
As far as the skills you use, take whatever you're good at, but
it's important to bring some sort of interrupt in case you have to
face a healer boss. I forgot to bring an interrupt with my Nec and
fought Demitrios the Enduring for around ten minutes before I was
able to finally kill him.
Talk to the King, then:
1. Go slow. There is never a time in this mission when you have to
face more than one group at a time.
2. En route to the arena there are 4 spots where you face patrols
who's path overlaps a group you'll have to kill. If you attack a
group at or about the same time a patrol is there, your party could
be in a lot of trouble.
3. Call every target you attack. The henches will concentrate on
your called target and kill them quickly.
4. When you have killed all the groups before the gate, there are 2
towers where stone giants and rangers are posted. Kill them BEFORE
you go through the gate. As a warrior, I just charge the tower and
call my targets. I can usually get a few hits in (through the wall!)
and the caster and ranger henches kill them off surprisingly fast.
If you don't kill the towers first, there's a much greater chance
you will encounter 2-3 groups at a time and likely Die.
5. When you finally make it to the arena area (where Dagnar is)
there are a few groups of heretics massed down in the bottom. If you
aggro more than one group at a time of these heretics, you will
probably die (unless you're a monk -maybe) *important note-if the
king aggros the heretics you'll just have to follow him and help
kill the heretics, because the king will not follow your pings or
commands to back off -he's stupid lol. I just follow a counter
clockwise course around the upper level around the arena hugging the
outside wall as much as I can. killing the enemies. *Be sure to catapult
the group of giants staged outside the west gate before going down.
Then I pull each group of heretics in the middle, killing them and saving Dagnar for
last.
6. After you kill Dagnar there's about a 2 minute cut scene to watch
(or skip)and the battle begins. I always run around using the
catapults until the enemy enters the arena, then I stand upstairs
near the king This part is really not that hard. Just call targets,
never straying far from the king.After a few groups a mantle boss
will come. He's pretty easy to kill. Then the jades and mursaat
eles, necros, and other mursaat will come along with a few mantle.
Keep them away from the king(always keep an eye on his health
bar).Anytime a mursaat ele gets close, kill him fast. He can hurt the king pretty quickly.
7. After a few groups of jades and mursaat, the mursaat boss will
come (aka "the hard part").It's very important that you save him for
last. That's kind of counter intuitive, but he has tons of armor,
and huge amounts of health. If you try to kill him first, all the
buddies he brings with him will kill your group and you while you
pound away on him trying to kill him.
8. When you finally kill the mursaat boss, you can relax a bit, the
hard part's over. The enemy will come a few at a time for about 10 minutes.
When you see a big red blob coming on the mini-map
that's Dorian's group. He will advance toward the east gate, stop
and go back around to the west gate. Take this time to finish
killing any groups that are left (there should only be a few enemies
there now) and go catapult Dorian as he goes around the keep. Then
go to the west gate and wait for him. It's a pretty easy group, maybe
around 10 mantle plus Dorian. Dorian has no elite, he just spams
banish and heal party. After you kill the entire party, it's over
You Win!!! you can run around and pick up your loot, go outside and
get chests(careful-there are still enemies out there)then talk to
the king. There's about a 8 minute movie to watch and finally you're
in Ember Light Camp.
I originally posted this in my guild's message board and copy and pasted it here. I can't figure out how to make it "word wrap" so it doesn't take up so much space. Anyone have a tip?
