Altar of Dumat

The Altar of Dumat is an optional side-quest in the Legacy DLC for Dragon Age II. It is a short-side quest which involves the collection of four ancient Tevinter artefacts, and then deciding whether or not to use the artefacts to perform a ritual in honor of Dumat, one of the Old Gods.

Acquisition
The quest can be acquired only when playing the Legacy DLC and only when Hawke is in either Corypheus's Prison - Farele's Floor or Corypheus's Prison - Tower Base. It is started by obtaining any one of the four artefacts as listed below (although all must be acquired to perform the ritual).

Walkthrough
You find the four Tevinter artefacts in the following locations:


 * Crown of Dumat - found in a side-room on the east side of Corypheus's Prison - Farele's Floor.
 * Dumat's Sacrifical Dagger - found in a side-room on the west side of Corypheus's Prison - Farele's Floor.
 * Dumat's Ritual Scroll - found up the stairs just after the exit (between two griffon statues) from the second main clearing in Corypheus's Prison - Tower Base.
 * Sacred Urn of Dumat - this one is found in the clearing after the area in which the Altar of Dumat is located in Corypheus's Prison - Tower Base. It is in a small cave just to the south of the area where you have a battle with Deep Stalkers and spiders.

Note that the fourth artifact is located beyond the Altar of Dumat itself - so you may only have three out of the four artifacts when you first encounter the Altar.

The Altar of Dumat itself is located in the third main clearing in Corypheus's Prison - Tower Base - which is up the carved stone steps on the opposite side of the clearing, having passed through the gap between the two griffon statues.

You have two substantive options at the altar - either defile the altar, or place the sacrifices.
