The Virtue is in the "Declining Viability" Category.

Awe, as it is, is a very potent ability (At +6) especially against Indept and non-high morale units early in the game.

As the game progresses, she becomes more and more fragile because her stats are based around Awe+6 being effective against a good chunk of the game (Anyone with lower than 16 Morale). She is regulated to using only her magic to survive (Which is acceptable because she her one path is very good and has some offensive and defensive spells that make it more bearable). If the mid-late game didn't use elite units that have high to mindless morale, or undead were not counted for their actual morale value but as a base. Or the holy aura of the Virtue burned them as a Fire Shield before they could touch the Virtue then that would make the Virtue much more survivable.

But as it stands now, any Death 2+ mage can kill a Virtue with the aid of some fodder.
