This quest is now Bugged since the November 19th patch. Upon doing your combine with the 10 blood, you will receieve a full inkwell, granting u the ability to create the clickable assignment order or w/e its called, to spawn the angry guards in each of 5 locations in Degmars.
HOWEVER: the step update for "Take 10 drops of blood and combine them inside the inkwell" does NOT UPDate!
