I think She looks like good toolbox master. So my thought about her is....
Stat & Ability
Low Df, High WD and Impossible to wound - They are usually Ressers' things, so she will be as tough as Ressers.
Flight - I think Free Flignt is always right.
The Thirsty Roots - 2 damage Aura is good, but it can work in some situations.
Rejoice in Rebirth - Very good healing ability, But it doesn't work with her action like A New Harvest.
Attack Actions
Wicked Silence - Good WP attack for utilities, but its damage is low.
Blood Command - Her Bread and Butter. it can use to healing / AP transfer and Its damage can be increased.
Tactical Actions
A New Harvest - Another Bread and Butter. It makes her other abilities / Actions and some scheme runs work.
The Queen has risen - Movement Trick. But I think its efficiency is low, So I think it must use for "important" model.
Upgrade
I don't talk about them, because I don't know their costs.
