Sharena

With respectable attack and speed, Sharena can run a reasonably effective Desperation build. That said, her stats lag behind some others who would fill this role better, so any help she can get from buffs make a world of difference. Luckily, thanks to Fensalir and her moderate defense, she isn't quite as paper thin as some others who might run this set.

The idea behind this Sharena is to make her a potent Enemy phase unit and letting her hang out in the back as support during Player phase. Only choosing to be initiated upon by a Sword or Lance (that doesn't have Lance breaker) when above 70% HP. As such having teammates with healing options can help her out immensely if there are multiple such enemies.

She can comfortably fulfill the role of a buffer if you don't have the Renais siblings or Delthea, as she can make use of her default Fortify Def and use Rally Atk/Spd as her buffing assist. The Fortify Res Seal also gives her buffing capabilities a little bump.

Thanks to her weapon Fensalir, she can also perform the role of a debuffer and stand in front more often, with Threaten Def and Threaten Spd being some key C skill slots. If running a debuffing build on her, you can opt for another assist skill such as Draw Back, Swap, Reposition, or keep her buff for a hybrid buff/debuff set.

--Huge Thanks to MolTreZ, over at the Fire Emblem Discord for brainstorming this with me. Without his ideas and experience, this build wouldn't even be half of what it is now!

With this build, Sharena will convert defense into attacking power, and reduce the strength of her foes, allowing her to fulfill three roles simultaneously; Debuff, Player Phase Tank, and Duelist.

Fensalir: Lowers the attack of enemies within two spaces by -4, making it harder for glass cannons to one-round, and allowing Shareena as well as other members of your team to safely duel affected enemies without having to worry about suffering as much damage as they normally would.

Armored Blow: Meshes well with Fensalir, and allows Shareena to shrug off hits she takes on player phase. Combining the -4 to enemy attack from Fensalir, with the +6 to our girl's defense from Armored Blow, means you're looking at 10 less damage per hit from any enemies that are 1-2 spaces away from her at the beginning of Player Phase. Steady Blow works fine as well, being a more offense-oriented alternative. The +4 to Sharenas speed allows her to double a few more of the units that can be classified as slow, and saves her from getting doubled by a few more melee units, while still giving her a fair +4 to defense.

Lance-Breaker: It's there to give Askr's cheerful princess the edge against fellow lance wielders. With it, Sharena makes up for the lack of Weapon Triangle advantage when dueling Lances by negating their doubles, and guaranteeing herself a double, no matter how slow or fast she is compared to her opponent. Debuffs like Seal Defense are also a possible choice, however they will seriously hurt our #1 fan in combat, and applying those debuffs won't be worth much if she's defeated in the process, so it is advised you stick with a Breaker skill if possible.

Finally, for her Passive C... It's really up to you! I have set Threaten Defense in the slot, as it works for almost any duelist build... However, if you want to get more creative, i got just the skills for you! So let me break down the main three choices:

Attack Smoke: It may seem redundant when paired with Fensalir, but hear me out! Using Fensalir and Armored Blow, Sharena won't suffer much harm from whatever fight she starts, so this means that killing the enemy straight away won't be as much of a necessity. Sharena can use Attack Smoke to cripple her opponent, and any other enemies within two spaces of that opponent (which will probably be all of them, considering how cramped the maps can be, and how the AI tends to move), making for a harmless Enemy Phase. Sharena herself is fast enough to avoid doubles, and bulky enough to take hits from those debuffed enemies, leaving her in the perfect position to retaliate next Player Phase.

Threaten Speed: If you sacrificed Brave Roy to Sharena for Steady Blow, i would consider this your best choice! With their efforts combined, Threaten Speed and Steady Blow combined effectively increase your speed on initiation by 9! Considering Sharena has a base speed of 32, that's pretty nice. Adding onto this, the speed debuff will also help allies, so that's another bonus to using this! Nukes and speedy duelists especially will be hurt by this, since they'll be vulnerable to getting doubled by units in your team that go just as fast, and they won't be able to sweep as effectively, if at all!

Threaten Defense: Nothing much to say here. Lowers enemy defense, making it easier to score kills for everyone on your team that attacks defense. It's not a bad choice at all, and is by far the safest. If you're unsure of what you want to do, inherit this.

Assist: Reposition is standard issue for tanks and melee fighters, since it can be used offensively and defensively. Sharena can use this to move units behind her, and have herself serve as a shield for the repositioned friend. Her solid defense and speed allow her to live a round or two even without proccing Fensalirs debuff, so there's no reason not to choose Reposition. Alternatively, just choose what your team needs most! If you feel you want Swap, or some other assist skill, use that instead.

Bonfire: The punch-line of this build! Bonfire allows Armored Blow to also benefit Sharena in the offense department, by boosting the damage dealt based on how high her defense stat is. Easily the best choice for this build, since it rewards Sharena for playing the role of a Player Phase tank and support by compensating for the lack of attack boosting Passives.

(Optional) Quickened Pulse: Not necessary, but very nice for memes and dedication! With it equipped, Sharena can proc Bonfire in one round, as long as she doubles and takes a hit. Lance Breaker, Threaten Speed, and Steady Blow all help ensure this happens.

This build is suprisingly useful and low budget, it boosts her average tankiness a lot more increasing her soak, the seal defense allows her to finish off a unit after the enemy phase/an archer to finish them off aftrr she hits them.
