hi guys, i just hit 65 and was so eager to enter Ancestral Catacomb (AC) . My pt has a marble tank, divine priest, wind mage, sin, me and a blood vamp. We did fine until 2nd boss, which keeps shooting the shurikens. Our healers couldnt outheal the incoming damage, and as a result, we all died . We revived and tried the 2nd time; somehow, we managed to kill the boss but the sin and the mage died. Is there a strategy for this boss?
We continued on, and kill the 3rd, 4th and 5th boss (mana drain is ridiculous_______). We came upon the last boss, the eye thingy thing. We didnt know wat to do when he calls out our name. Tried to run, but he 1 hit KO 2-3 ppl, then KO rest of pt . Any one knows what we have to do when he has "the eye on us?" I will really appreciate if someone could give me some tips for this instance. Thanks

get a bard =P, and itll target one person if they stay alive, and it doesn't quite one hit, just have priest focus on the tank and bard aoe healing ^^ i think it hit me for 18k so had about 3k hp left

Yes, get a bard
Once you figured out how the bosses work this instance isn't really hard. You can also do it without a prot or priest - a bard and vamp are enough. Did a few runs with this constellation and nobody died so far.
For the 2nd boss: get as close as you can to him. After he keeps rotating you maybe have to change your position a bit but stay close to him.
At the last boss go also close to the boss and stay with the whole party at one point together all the time. He calls a name and every partymember has to be close to this person. So just stand still there and don't run

And yes, the mana drain boss is pretty annoying.
