I think it'll get the Touch of the Void treatment, but currently doesn't have the "cannot be used in raids" flag yet.
Couple other notes:
-DPS caster trinket: I was able to get it to proc about 50-55 secs apart, so really good uptime
-It was working inside ICC
-As someone else mentioned 4 bosses in HFC are demons
I really think it'll get that flag though.
