Method to Acquire - Go to the right house in the northeast on Chapter 9 and she appears on Chapter 10. If you go to the left house on Chapter 9 or neither house, she appears on Chapter 11. Speak to her with Klein to recruit her.
Damage - Tate has exceptional damage for her class. Strength isn't her best gain but it's still very good.
Critical - Her critical is not as good but that can be remedied with a Slim Lance and a few supports.
Speed - Excellent. She should be hitting twice the entire game.
Dodge - She has a pretty good dodge, but watch out for Axes and Lances after promotion.

Rating - 8.5/10. Tate is the best FalcoKnight on Hard Mode, but she may be difficult for you to raise on Normal. Also, the Dragon Riders and Dragon Lords of Fire Emblem 6 are exceptional. If you use Tate, don't give her the Delphi Shield because she has a high chance to dodge attacks unlike Miledy and Zeiss.
