Reservation Mastery damage increase

Hello ,
I took the Reservation Mastery from the Sovereignty wheel , specifically the :
,,8% inc dmg for each of your Aura or Herald Skills affecting you ".
The damage doesn't increase with Flesh and Stone , shouldn't it increase ?
Flesh and Stone says : Casts an Aura that affects YOU .
I can understand banners not working even though they have the Aura tag because u cast the banner and the banner gives u the buff , not an aura . But Flesh and Stone should work , no ?
