Faceless Mask of Vengeance

This appears to be the easiest 2nd mask to get in Horrific Visions, with this one nabbed in Stormwind in adjacent to the canal waters between the Old Town and Trade Districts.

Mask effects: Killing enemies will bolster their nearby allies damage by 15%. Increases corrupted mementos gained. Enemy damage increased by 25%. Enemy health increased by 25%.

To get the mask:

1) One mask required. You'll only see the Vengeance mobs you need to kill if you're wearing at least one mask.

2) Once in the vision, take the southern passageway and small bridge out of the Cathedral District toward the Trade District. Instead of entering TD from its northern door, go left and round the bend alongside the Stormwind Canal, taking out some minor mobs along the way, to the canal's southeastern tip at 71.69

3) The half-dozen or so Vengeance mobs are a mix of melee and caster non-elites. Once you dispose of them, be sure to loot the mask on the post erected where the mobs were originally gathered.

4) Once you've obtained the mask and related quest from the post, you don't need to do any other objectives.

You are a life saver! I misunderstood another post and thought it was void creatures IN the canal I was to look for. Wasted 13 minutes looking for such. Had killed the mobs you mention so I went back and looked for the post with the mask on it and BAM. Thanks for the info!
