Grand Court of Sebelkeh Mission... Impossible? Help!

(Sorry for my poor english.)
I have this mission in Vabbi: Grand Court of Sebelkeh and I did it for an hour again and again but I can't complete it. I do it with heroes and henchmen after reading a guide at wikipedia but it can't help me, I get killed very fast. I don't even understand what I need to do... run in the middle or go to the rifts? (bad english). because I tried both several times but I die anyway. any hints or ideas before I give up forever? : ( thanks!

you need to close each rift, one by one. In the mean time, make sure that the altar in the middle does not get occupied. If that happens - mission over.

So what you can do is keep an eye on the progression of the 'capture bar' of the altar. You go to one rift, kill all the bad guys and wait there until the rift closes (check the progression of the bar that denotes the closing of the rift). Then go back to the altar and clear it. Then take the next rift - back to the altar. Then the last rift and the altar... Done!

When you first get into the mission, run all the way to the middle and just hold your ground until you've killed all the attacking groups. As Tharg said, at this point just attack the nearest altar (where the tormented claw is), clear that group, and wait until you capture it. Run back to the middle and kill the Blasphemy. Rinse and repeat with the other altars. Sometimes you may need to run back and recapture an altar if an enemy spawned there but once you cleared the enemies it is pretty easy. I find that minions and spirits help a lot since it is such a small map. Since you have to take Tahkihora (sp?), Ray of Judgment is nice to clear stationary enemies at the altars. The main thing is to keep an eye on the middle altar, if it falls to the Blasphemy; game over. It's ok to let him sit there for a while but when the bar starts getting like a 1/3rd red or so, you better stop whatever you are doing and run back to the middle.

I went in with minion masters and cleared the middle but can't close the rifts, even if I stand next to it and click on it. why won't it close? I can't kill the claw monster next to it, it kills me in a few hits. all I can do is killing that B guy so he can't use the altar, but when he dies, a lot of glowing things come out of it and it kills us... it's impossible and this is like my 20th try... *sighs*
this is what I'm talking about (screenshot): http://i45.tinypic.com/ayvdol.jpg

yeah, you have tyo kill the Torment Claw. Killing it starts the process of closing the rift. Let me know your in-game-name and if I see you on-line I can help as well

umm what builds are you running? the claw can only hit things near it so kill it with ranged attacks if he's wiping you. to close the rifts, you need to have more of your team on there than enemies. you'll see a progress bar start going down.

I hated this mission when I first started playing
If you don't already have them, look for good hero builds on PvX wiki.
Spirits and minions will help a lot especially with the torment claws, let the minions take the melee hits.

The key on this one, besides good builds, is watching your timing. You must stand under the rift until the bar is all blue so once you kill everything at a rift you will usually have to stay a bit so flag your party back to the center to kill the Blasphemy and unbound energies while you finish closing the rift. Then head back to the center to pick-up your group and go to the next rift.

let us know how you're doing and good luck!
