Selena (Fates)

It's Selena Miku! This build may seem controversial but it's definitely a fun one. Selena is known for her low Atk but balanced Spd, Def, and even Res. Her best boon, in my opinion, is Spd, her attack will only age worse as the game progresses, but her Spd is still relatively competitive to today's units (at least at the time of this writing). Most people opt to use her prf, Selena's Blade (+Eff) (which is an excellent weapon), but she works great with other weapons too. This summer, we got a new inheritable weapon from Bridal Oboro, Pledged Blade, which will be the weapon of choice in this build. We'll go into more detail on that in a bit. This build essentially raises her stats and damage output to those comparable to generation 3/4.

Pledged Blade+ (+Spd)
This inheritable weapon is amazing and by far the best one, essentially if a【Bonus】is active on the unit, in this case Selena, grants Atk/Def+4 and Special cooldown charge +1 per foe's attack during combat. She essentially has a dual breath built in at the cost of a【Bonus】, which this build will activate as you'll see later. I went with the Spd refine as Spd is important for another skill that's featured in this build.

Reposition:
I just kept this on as she is the "Repo" fodder everyone loves. I personally find myself using skills like Smite the most.

Noontime:
Noontime seems a bit contradictory to our build but it plays a key role in sustainability and with Pledged Blades effect, she'll be procing Noontime every other attack on the enemy phase.

Fury 4:
Fury 4 is definitely an expensive skill to raise all her stats by four, but the important thing about the skill is the eight recoil damage Selena will be taking after combat. The Noontime is meant to help with this to try and stay at around 75% HP for her magic to truly show her colors.

Spurn 3:
For some odd reason, Spurn is not an available skill on the site so full disclosure here, REPEL IS NOT THE INTENDED B SKILL. Spurn has the same damage reduction capabilities compared to Repel and Close Call, but it's gimmick is a mini-wrath-like skill, "If unit's HP ≤ 75% and unit's attack triggers Special, deals +5 damage when Special triggers". Now you may have put two and two together. Fury 4 is to bring us down to Wrath level so when Noontime procs, it deals +5 true damage, while also healing us above 75%, to only go back down to 75% after combat. Thus we are trying keep Selena in a wrath-state loop.

Rouse Atk/Def 3:
This is the skill that will activate Pledged Blades "Special cooldown charge +1" ability. It's very straight forward, Atk and Def +6 when solo (stacks with Pledged Blade for a total of +10 to both stats).

Spd/Res Solo 3:
Another straight forward skill, this is meant to increase her Spd, to activate Spurn's threshold easier and to increase her Res stat so it doesn't lag too behind from her Def (that way units with adaptive damage, like Annette, can't exploit a weaker stat as easily).

My Selena is fully invested at +10 merges, +15 Dragonflowers, and she is Summoner Supported. This how her stats look like in the "optimal scenarios" which aren't too hard to get:

HP 54 (49 base, +5 from weapon refine)
Atk 62 (48 base, +4 from Pledge Blade effect, +4 from Fury 4, +6 from Rouse Atk/Def 3)
Spd 60 (47 base, +3 from weapon refine, +4 from Fury 4, +6 from Spd/Res Solo 3)
Def 55 (41 base, +4 from Pledged Blade effect, +4 from Fury 4, +6 from Rouse Atk/Def 3)
Res 47 (37 base, +4 from Fury 4, +6 from Spd/Res Solo 3)

This may not be her highest attack stat possible, but we do slightly make-up for it in +5 true damage and this definitely makes her a beast. She has no problems with green units and little to none with red. Blue units may pose a challenge at times, but even then they can't shut our favorite tsundere down!

A lot of Selena's strength comes from the fact that she has a generally even stat-spread. While other sword users such as Mareeta and Ayra double down on attack and speed, Selena's balanced stats makes her much more flexible with how you build her. This build capitalizes on that, giving her everything she needs to be a perfect duelist.

Selena's Blade (+Eff):
A refine can make or break a unit in FEH, and Selena heavily benefits from hers. A +10 to her specials significantly increases her damage output and negates her fairly average attack stat. It's worth noting that unlike other units with a Wrath ability on them (such as Spring Hector or Spring Kagero), the +10 damage does not interact with abilities like Glimmer. It's also worth noting that her pref's ability will compare stats at the beginning of combat, rather than during combat. You'll see why this is important later. Her effectiveness against armors, while not as important, makes her a high threat against annoying armored units like W!Sothis and Spring Idunn.

Reposition:
A good skill to get other units into the fight. You can change this up, but I personally prefer reposition.

Moonbow:
With her refine, specials are important, and Moonbow makes it easy to activate her refine's ability. It also helps out her attack stat, as it ignores a portion of the enemy's defense. Luna would also work very well with her if you have skills that lower special cooldowns, such as Time's Pulse or Infantry Pulse.

A Slot: Atk/Spd Solo 4:
Here's where things get interesting. A +7 to attack and speed when she's by herself gives her a lot of player phase potential, and prevents her from getting doubled from most units. With this, an Atk Boon +10 Selena can reach 56 attack and 46 speed on her own, assuming you haven't given her Dragonflowers or given her Summoner Support. Those stats are on par with a lot of the Gen 3/4 sword users nowadays. Not only that, but her weapon's ability won't count the attack boost this weapon gives her. So in addition to her +7 atk/spd, she gets an additional +3 to all stats, assuming the enemy has a higher base attack stat (which in all likelihood they do).

B Slot: Repel 3:
This ability gives her much more tankiness in addition to her already fairly good defense and resistance stats. Her fairly high speed/resistances combo allow her to be an effective enemy phase tank regardless of what unit she's up against. Because of her similar defense and resistance, she won't be largely affected by skills such as Sorcery Blade or weapons such as Annette's Crusher. This also gives her the advantage against high attack units such as Effie and L!Seliph, both of which can dominate the player phase if you're not too careful. You could use Close Call here as well, but be warned that doing so might push her back into the vicinity of another ally, rendering her solo buffs useless.

C Slot: Rouse Atk/Def 3:
This helps to buff her stats even more, since you want her to be by herself during combat. The attack and defense bonuses help against other melee units, and makes it hard for them to one-shot her. The only downside to using this is that the buff may cause her weapon's skill to deactivate, as buffs are counted toward the attatk comparison.

Seal: Spd/Res 2 (Spd/Res Solo 3):
Unfortunately Spd/Res Solo hasn't come out on this site as a usable seal yet, but this can work as well if you'd like. Spd/Res Solo only enhances her previously mentioned strengths. The +6 additional speed boosts her player phase potential as well as the damage reduction on repel. The +6 additional res helps her to stay alive just that extra bit longer. It also allows her to tank a lot of magic damage from mages, giving her or your team a chance to follow up.

As of right now, if you were to have a fully invested, summoner support, +10 Selena, her stat-spread would be this, assuming she doesn't have any nearby allies, debuffs, or a higher attack than the opposing unit:

HP 51 (48 base, +3 from weapon refine)
Atk 69 (53 base, +3 from weapon passive, +7 from Atk/Spd Solo 4, +6 from Rouse Atk/Def 3)
Spd 59 (43 base, +3 from weapon passive, +7 from Atk/Spd Solo 4, +6 from Spd/Res Solo 3)
Def 49 (40 base, +3 from weapon passive, +6 from Rouse Atk/Def 3)
Res 45 (36 base, +3 from weapon passive, +6 from Spd/Res Solo 3)

Now that's a unit. If you wanted you could switch up her C Slot with Time's Pulse 3 and Moonbow with Luna and achieve similar results, but I'm working with this build right now and by god can she murder arena.

In essence, this build serves to make Selena a Jack-of-All-Trades, but better. In fact, with this build, Selena can solo a bunch of blue arena units if she's lucky, such as Nowi, Effie, B!Hector, and other threatening units.

Selena's blade works well with her low attack, because if her opponents have more attack than her she gets +3 to all her stats. The attack check begins before the battle, so skills that give attack during combat are not taken into consideration of her weapon. Her stats are very balanced to where you'll need her at higher merges to make her work better. Her super boon in attack would ironically make her have too much attack at +10 merges, making her unique refinement a problem to utilize, so this blade works better if you work around her solid bulk.

Edit 2/16/2020: Outdated. Still run this but I have a new build I run more

Where to begin?

Well, first off, this is my first build here in a while, and it's a pretty dang exciting one, featuring everyone's favorite walking inferiority complex, Selena.

She's always been a mixed bag of strengths and weaknesses. her mixed bulk has always been a pretty strong point in her favor and her decent speed means she can put that to good work, but her attack leaves a lot to be desired, and her stats across the board, while decent, leave too much to be desired, they're just too balanced.

Cue Selena's Blade, her very own prf weapon hailing from Fire Emblem Fates...and what a personal weapon it is. As though it were tailor-made for her (It was), it retains her base weapon effect being an armorslayer, but brings a whole heaping of helping stats for the measly cost of having 3 less attack than the opponent. For those who might be unfamiliar with just what made Selena so not good, her base attack of 25 means that even when she does hit, she'll be hitting like a wet noodle. Her superboon helps a tiny bit, but her attack is still only a meager 29, or 45 with the weapon applied. This is usually enough to run under many units as it stands, but her strength doesn't lie in her attack stat.

That's where the rest of the set swoops in and says "Hey world, remember this attack drop Fortress Def/Res 3 gives? What if you could put it to good use?" And hot dang she answers that question with the electric energy of a A Certain other tsundere. Not only does her weapon weapon synergize with FDR and its attack drop, but when all that is taken into account, her total non-visible bonuses from skills and weapons becomes 1/3/9/9.

Of course, that stat total is assuming you run her refine, the every helpful Wo Dao effect...but that might not be the most optimal play with our girl here. See, by giving her any non-attack refine, you further augment her defensive capabilities either directly (in the event of def/res refines) or indirectly (in the event of speed refines). Overall, her weapon shifts her from a once mediocre mixed tank who was forced into a defensive role with a reliance on special damage into a beast of a unit that has a total BST increase of +12 putting her in the same camp as gen 3 infantry units.

The rest of the build is down to personal preference. I usually opt for an effect refinement with Moonbow and the other skills vary from there. Null Follow-Up gives her extreme utility against the ever potent armor teams, while the renewal seal gives her sustain over time. Swapping these things out on occasion is most certainly not a bad idea, and her ceiling has been raised significantly by her newfound weapon.

Anti-green Selena designed to deal damage upon foes first so that her teammates can finish the job. Also meant to go against axe Hectors. (The stats on this one are with +1 and a dragonflower). +SPD is the ideal boon.
Selena's Blade is good to take advantage of her low attack and power herself even more. With the effect, she can dish out high damage.
Reposition to get others out of the way, or Pivot if she needs to get out of the way herself.
Ignis takes advantage of her high Def.
Triangle Adept helps her dish more damage against the axe foes.
Seal Def helps lower their Def so her allies can deal more damage attacking them.
Threaten Spd allows her to outspeed them even more.
For a Seal, I use Defiant Atk (which is kind of ironic), but Defiant Res or Def works as well since she will probably be taking damage from the foes as well.
