Fire and Death Attunement or Unseen Fury?

Shooting for a Bard/Nightblade/Riftstalker build mainly for PvE support, I'm wondering which one of these would be more effective regarding Cadence. Here is the build in question:

Would the 3% damage boost from Fire and Death Attunement outweigh the 15% gain in attack power from Unseen Fury? If I drop Fire and Death Attunement completely and fill out Unseen Fury it would also open up Planebound Resilience in the Riftstalker roots. Any input would be much appreciated.

hrmmm. . . anyone with a similar build?

you do almost zero fire or death damage.

It gives +3% to all your damage.
-15% damage to you from fire and death damage.


Back to the point:
I think you'll be more mileage out of the extra +9% attack power rather than the +3% damage. I don't think the +3% damage affects things like Coda of Restoration.

I'm unsure, however, how the -15% from fire/death will play out.
