A sacred seal belonging to the Godskin Apostles, distinguished by its obsidian inlay.

Symbolizing mastery over black flame manipulation, this sacred seal acts as a catalyst, amplifying the effectiveness of godslayer incantations.

No Skill:

This sacred seal lacks an intrinsic skill. In the absence of a skill, the skill from the corresponding armament in the opposite hand will be executed.

Acquisition Method:

Locate in Stormveil Castle. From the 【Rampart Tower】 grace, take the elevator down to the feasting hall where the Grafted Scion was roaming.

Exit into the courtyard with all of the waiting archers. Make a hard left into a small stairway that goes underground.

You'll find a room that is guarded by four Rats, and ahead is a doorway that is blocked by a white fog. To dispel the fog, you will need to use a Stonesword Key on the Imp Statue. 

You'll find a stockroom on the other side; the room has a treasure chest containing the seal.
