Alright, I'm sure many of us have gotten frustrated with Thunderhead several times. Well... here are some tips for you. I've completed this three times on the same character (wanted to help people out) and I've been able to figure out almost every trick to that.
so this list might be kinda short or kinda long
Party suggestions
-2 Rangers (when you get to the fort, have the rangers man the catapults and they also need to pull mobs)
-2 Tanks (any type of tanks)
-2 Healers (can be E/Mo or Mo/E)
-2 Nukers
Now you could switch it up a little and have 3 tanks and 1 ranger or 3 nukers and 1 ranger but that's about it (this is my opinion btw).
Your party MUST be organized at doing everything, here are a few tips while you do your mission
-Make sure a healer talks to the King
-Do NOT move to the next group until both healers have full energy
-Have the ranger(s) pull mobs so that you don't have to fight too many at once and thus lowering your chance of death
-Every party member must cooperate, if one person screws up, your whole team does
-Before you fight the mob right in the middle of the city (the one with the boss) where it says "Destroy 8 groups" or however many it is, go on the top from the right side and kill the giants and rangers there
-When you reach the fort and kill the things on the side, hug the wall to the side and pull the boss in the middle so that its alone and you don't lure the other groups.
-Make sure that the Rangers or whoever mans the catapults know that they hit the dark spots, so that they won't waste their time hitting everything
-When the rangers are using the pults, everyone else stays in the middle of the fort
-When the second boss comes at the fort (after the cutscene), EVERY party member should go back to where the king is at all costs, if you try to fight it from the middle, you're screwed. The boss is either a jade boss or a mursatt boss
-After that you are pretty much done with the mission, stay where the king is and make sure that he doesn't die.
Add any suggestions if you want. I think I covered most of it. (there's a glitch that you could use but I didn't put that in, too hard to explain)
Good luck. Sometimes I'll go to thunderhead and help some people out on this mission. For me, its a challenging mission and its actually quite fun. Met quite a few friends on this mission.
