The Angel Wing appears as a bow with feathery white wings making up most of its body. The arrows appear to be made entirely of white light with a blue aura, similar to the body of Light Godcat.
The Angel Wing provides bonuses to both Attack and Magic Attack, as well as a small increase of Accuracy. It does not shine at the offensive, however its ability to cast Arrow Rain between turns combined with the chance of weakening the targets, or, when used together with Status Replacing Flairs, inflicting other status effects instead, proves as a great supportive option capable of easily disrupting entire enemy waves while still enabling Anna to perform another action during her turn.
The Angel Wing also boosts the power of Holy-elemental attacks and provides Anna with resistance against Earth and Holy elements, as well as to the Weaken status effect (immunity at Level 5).
