While doing the Blood Frost and Death Monolith (not empowered) I released and killed two imprisoned mages. Upon both kills I saw “Prophecy Fulfilled”, and as you can see from the screenshot, 2 of my 8 possible fulfillments were consumed. However I assure you, no Unique Armour with 8 Weaver’s Will dropped on either occasion. I have not yet killed a boss in a Monolith with this prophecy but will update here when I do.
I tried to paste in my Player-prev.log, which may represent the play session in which this occurred, but that made my post longer than the limit allowed by the forum.
Update: I killed the boss in Blood Frost and Death Monolith (not empowered) and got a drop of unique gloves with 17 Weaver’s Will. My Prophecy now says Fulfilled 3/8 times.
I didn’t realize Gloves would be a possible drop for “Armor” (I was expecting body armor). I do have a recent drop of other Unique Gloves that started with 16 Weaver’s will. However if that were due to this prophecy I still have 1 of the 8 fulfillments unaccounted for (no other drop of anything with 8+ Weaver’s Will).
It has a chance to drop any of the Weaver’s Will items … I’ve been farming these prophecies and the drop rate is inconsistent when related to Boss Kills where an item may or may not drop on the Kill. Rare Monster kills seem to have the best chance for drop rates. I have yet to see a Relic drop from these, but its all RNG.
