There is a new BP from a new quest that has this too.
The quest is in the chef line where you talk to someone on the docks in KP then go to TG to talk to someone who sends you all over for ingrediants (Chelsith at end of it) and then seems to end suddenly.
As of last patch there is one more quest in the chain where you talk to the person on the dock again and get a medal to give the chef. The chef then rewards you with a choice of nice legendary items. The BP is about on level with the Divine Raps set BP - I'm interchanging them situationally.
The only question I have about these is that when I do my group reactive the ward usually lands on 1-2 people - but it always says "self" as target. We were crawling deep seb last night so I didn't have time to stare at it much to figure out if it was really on me or if that was a bug in the display... if it really only proc's on self instead of the person healed I wouldn't want to wear it.
