The next Mythic Hero has been revealed, and it's Ashera from the Tellius series!
She is an infantry colorless tome user with a busted tome called Order's Sentence: it gives her a +5 boost to all of her stats during combat if a bonus is active on her or if her HP is at 25% or higher. The tome also has the additional effect of granting an added bonus to her Attack based on the bonus total of an ally within 2 spaces: to illustrate, if a nearby ally has a +6 boost to all of their stats, Ashera gains a +24 boost to her Attack! YIKES!
And her tome also has a very unique animation: the first attack animation to involve a complete camera angle change where the camera pans to the sky to show her directing that death beam from above!
She has the new Atk/Res Ideal 4, Lull Spd/Res 3, and a unique C-skill called Order's Restraint which provides a +6 boost to Atk/Def to allies within 2 spaces and the new "Null Panic" effect for them, and Ashera can gain the same effects for herself if 3 or more allies are within 2 spaces of her. Like the name implies, "Null Panic" nullifies the Panic effect on a unit.
The other characters to pull in this banner are Legendary Roy, Legendary Eliwood, Azelle, Legendary Azura, Peony, Ronan, Triandra, Freyja, Dedue, Legendary Corrin, and Legendary Claude.
Might try pulling for Dedue, with green looking to be a great orb to pull here, but otherwise will probably pass.
