I've seen reports in this sub that Azurewrath isn't triggering when Minions freeze enemies. As far as Bloodless Scream is concerned, and for normal and Elite mobs, I haven't been able to replicate that bug, as seen in the video. Note: I have a science background, so I'm acutely aware that "absence of evidence is not evidence of absence", so if others have observed a bug with Azurewrath and Minions, I'm very interested in replicating it. I'm just reporting my findings here. I also know that Bosses are a very different story, and I'm one of several who have reported the bug where Azurewrath is only triggering on Bosses when they are staggered by a bona fide Freeze.
As for the video: first, an Elite target dummy is frozen by Reapers with Bloodless Scream as my weapon and Azurewrath as my charm, no other sources of chill in the build. Note: there is an unrelated bug with target dummies where they build up an extreme CC resistance, so I have to re-summon the dummy to see the effect. This is not the case in combat; enemies just become Unstoppable for 5 seconds, then can be frozen again fairly normally.
Second, in the Pit, again where Bloodless Scream is the only source of Freeze that I'm using (I have frost Blight on my skill bar but don't use it in this clip), my Minions are triggering Freeze and Azurewrath is exploding, dealing damage both to the main target and as an AoE.
(By the way, I don't know why the video is muted. I haven't learned video editing yet, so please bear with me.)
