Dagr is this March-April's Mythic Heroine in Fire Emblem Heroes.
A cautionary tale for would-be princesses...
NintendObs Daily. Wednesday, March 31.
That sure escalated quickly. Just one chapter ago in Book V Chapter 4 The Vital Blade, Dagr was introduced in Fire Emblem Heroes as the second princess of Jötunheimr, the kingdom of the Jötnar, who are essentially a tribe of taller, stronger than average human beings. She immediately turned out to be an antagonist in a bid to prove herself worthier to the throne than her twin sister, then joined our cause as Prince Alphonse and team defeated her. Boss characters that important in the story tend to be playable long after their first appearance but here she is, ready to be summoned. She's definitely a force of nature, and since the Nintendo Treehouse's Tips & Tricks video did not recommend any Assist Skill, I would recommend Draw Back in order capitalize on the Pathfinder ability she gets from her exclusive weapon Skinfaxi.
