Hmm that could be. I read the part were Xenovia used it in Battle ( LN24 or 25 I think) and the Scabbard not only protected her against direkt Damage from Appolon, but also against secondary damage from thrown away or into something, which also must hurt.

If you look at it I think maybe it is a combination from a Shield Aura and a limited healing ability. Maybe with a max capability like the Sacred Gear Cancellar.
