This is part takes off after you have loaded the Vimmark Chasm.

After the load, start making your way to the next seal. At the seal room entrance you will get a cut scene of Janeka, and her Grey Warden Unit stopping you in front of the room, and wanting to end your life, but instead end her units life. After the cut scene you will have to fight the unit. After the unit is dead walk around the room, and use the four eagle looking statues. When the four statues have been used walk over to the seal, and you will trigger a cut scene, of Corypheus rising.

After the cut scene you will have to defeat Corypheus.To defeat Corypheus simply attack him until he say’s ” Dumat! Grant me Your Power!”. At this point he will summon two fire walls and will circle the room, with them. What you have to do is avoid the fire walls, and touch each of the statues, which will summon two shades that you must destroy (each statue has 2 shades, so a total of 8 shades must be killed to attack him). Once you have done this you will be able to attack him.

When you have damaged him enough he will again go into an unattackable area and will do the same thing. You must repeat what you did when he did the fire wall (touching the statues and killing the shades) only this time there will be a maze that block your straight path to the statues. Make your way through the maze and do the statue thing. Now once again you will be able to attack him.

Once again when you have damaged him enough he will retreat back on to the un-reachable area and do the fire wall, maze trick again. But this time the maze is electrified, so you can not touch the walls or the electric barriers or you will be damaged. Once again run to all the statues and kill all the shades, this will be the last time you have to do this. Once he is back on attackable ground, just unleash hell on him. When he is on the ground for the last time he will teleport around the battle area. After you have killed him, you will get a nice little kill scene.

After the kill scene walk over to Larius for a cut scene, of him regaining the ability to think. After that cut scene you will get the ending cut scene of the DLC.
