This mask isn't really a random drop. It drops off of "trash" but drops in a specific area of the zone. Got it to drop three times off the same trash in the area just south of he Possessed Brute. Had a really good tank so we just went around rapin everything from the Cleaver all the way up to just about the 6 points. Like I said it dropped 3 times from lightning warriors in the area south of PB :) hope this helps you guys out.
no, it really is random... i have seen 4 drop, all off trash but in different areas, 1 was at a camp near the projection of arcana, 1 down by Nueromancer Vionne, 1 near the Projetion of body, and the other was at the "6way" camp
Group of us were heading a camp invis. The cleric's invis wore off and got agro from a noc. Sadly she died, but when we killed the noc this dropped!. Got 1 happy warrior.
Yep, can confirm from a discordling enchainer and from a lightning warrior diodite, quite rare, but frequent enough to be a motivation. Seems to drop about one every 10 hours of nice fast pulling.
