Mana Res Efficiency of Stance Skills from Attack Mastery provided no reduction. (Blood Magic)

My character received no reservation efficiency from Attack Mastery's Mana Reservation Efficiency of Stance Skills when using Flesh And Stone with Blood Magic Keystone.

First image: Character with no life reserved, Blood Magic active.


Second Image: Life Reservation with Flesh And Stone turned on, no reservation efficiency from passive tree.


Third Image: Character with reservation efficiency of Stance Skills applied, but burdened with the exact same reservation amount as without the Mastery.

Mana is not life.

Yeh, not really sure what you expected MANA preservation effiancy to do to your LIFE preservation.

Oh! First time using Blood Magic. I assumed the reservations translated over. My bad.
