Well the Nizarria Assasin Hood works... though I think that is SC or Sub-reward. I am knowledgeable for Appearance but... I really am blanking here. If I find one I may respond back here again should I remember to.
I know of three, atm, but it's early so I might be forgetting what my alts have. This: \aITEM -312733248 1142375062 0 0 0:[Insidious Coif]\/a you can only get if you're an assassin, from danak, the VP armor This: \aITEM 494312195 -318362540 0 0 0:[Shroud of Perpetual Aggression]\/a you get via dungeon marks in the dungeon maker section of marketplace This: \aITEM 47533772 -2139765227 0 0 0:[Hood of the Ebon Mask]\/a from a faction-ish merchant in darklight woods, they show up once you do most of the quests in zone Hope some of those work, included the assassin-only one because I don't know what class you are
I seem to recall getting Shroud of Perpetual Aggression from doing the City of Freeport timeline with my Ranger, then passed it on to my Assassin. Note- The horns on the shoulder are not part of the hood. those are from the shoulder appearance armor I got from ToFS, though I want the one you get from silverwing, hood and shoulders. anyone on Freeport server want to group up and take him out?
