Dumat's Sacrificial Dagger is a plot item in Dragon Age II.
Acquisition[]
It is found in a side-room on the north side of Farele's Floor.
The accompanying note reads:
(The writing on this ancient parchment is barely legible, but it appears to concern a Rite of Silence.)
Raise your face and hands to the skies and speak the words:
"O Dumat! O Lord of Silence! Accept these sacrifices made in your name! Grant us your power, and all that we seek!"
Involvement[]
It is one of the four Tevinter artifacts Hawke must find to complete the ritual for Altar of Dumat, an optional side quest in the Legacy DLC for Dragon Age II.
