Information about how to recruit Lysithea in Fire Emblem Three Hopes.
In Fire Emblem Three Houses you could recruit many characters simply by getting specific stats and skills high enough. Once done, they’d be impressed enough to realize that studying under you would suit them better than petty considerations such as life-long friendships, national loyalty, familial duty or even religious conviction.
Unfortunately characters in Fire Emblem Three Hopes aren’t quite as malleable - some characters will join your faction as you progress the Main Questline, usually due to story contrivances entirely outside of your control. The rest, however, must be met in battle and “persuaded” to join you… often by lumping them on the head enough times to realize that they’d be better off defecting than decomposing.
Character Recruitment Strategies
In the case where a character can be persuaded to join you, this “persuasion” effort is achieved via the deployment of a Strategy. When you start a battle in which a character can be recruited you’ll first have to pick from a variety of available [Strategies]. You can find more information about Strategies on their own page, but for the purposes of recruiting characters you’ll be interested in any “Persuade [Character]” Strategies, which you must select prior to the battle to ensure you can utilize said Strategy(ies) during the battle. Deploying Strategies in turn require you to expend Strategy Resources, a currency gained by completing [Side Quests] during the chapter leading up to the Main Quest where enemy characters can be recruited.
During battle, when the character you wish to recruit spawns you must activate the Strategy to persuade them by entering the battle menu before you defeat them. If you defeat them without activating the Strategy - even if you selected it before the battle - they will die and you will not be able to recruit that character for the rest of the playthrough! Once the Strategy has been activated, the area where the Strategy is in effect (usually where the target character spawned) will be surrounded by a purple glow. Merely defeat them in this area and you’ll recruit the character.
How to Recruit Lysithea in the Scarlet Blaze Route
During the Main Quest in Chapter 7, you will be able to deploy the Persuade Lysithea Strategy by expending 10 Strategy Resources. You should have a total of 50 Strategy Resources if you capture all of the regions prior to beginning the Main Quest. At the beginning of the battle, you will be told to capture two strongholds, which will lead to both Raphael and Marianne (recruiting them with the proper Strategies). After doing that Main Mission, the next one will ask you to capture another two strongholds, again with one to the north and another to the east. For the purposes of recruiting Lysithea, head to the eastern of the two to find her. Initiate the Strategy when it pops up, then defeat her to get her in your army once the battle is over.
