Sheena

Sheena! Honestly, I know nothing of her from her original game, but I love her in Fire Emblem Heroes. She's so tough! And recently, finally, I got my wish to earn Distant Counter for her.

The listed abilities here are what I currently have on her, however, some changes are pending.

As one may guess by my choice of weapon refine, I am actually considering trying to pull for a Speed (super)boon, and subsequently stack her Spd as high as I can. With a Spd boon, Sheena starts out at an okay 29 Spd. With weapon refine, this goes up to a better 33. Add a teammate using Hone Armor, Spd Tactic 3, or similar and now we are at 39. Add another teammate with Goad Armor, and we're already at 43 Spd. This isn't even taking into account the ability to push it further with Sacred Seals, and debuffing the enemy also helps narrow the gap. In other words, it is quite possible to ensure that Sheena earns doubles on both the Player and Enemy phase with a little investment and good positioning, and such is my goal with her. This opens up her B slot for Special Fighter, which pairs excellently with Slaying Axe.

With that all in mind, this is my plan for her:

Weapon: Slaying Axe+ (+Spd)

The Slaying Axe's effect helps get specials proccing more often, and the +Spd refine helps push Sheena that much closer to naturally doubling in both phases, as described.

Assist: Swap / Reposition

Right now I have Swap on Sheena, but I may adjust this later. Swap is better if she is not able to boost her movement, I feel.

Special: Iceberg

Iceberg or Bonfire both would probably work fine here. Any special with a cooldown of no more than 3 is preferable for a build of this kind, since thanks to Special Fighter + Slaying Axe they will then proc on every single combat.

Generally, I feel that damage that ignores Def/Res like Iceberg or Bonfire is best, since it allows Sheena to take on e.g. Red foes, against whom she would otherwise struggle to deal damage.

Passive A: Distant Counter

No explanation needed here. Distant Counter ensures Sheena can take on any foe from any range.

Passive B: Special Fighter

Special Fighter in Sheena's B slot is only worthwhile (in my opinion) if her Speed can be pushed high enough to make up for the lack of Vengeful Fighter. As noted, her weapon refine, IVs, teammate support, and Sacred Seal can all help in this regard. Anyway, paired with Slaying Axe, Special Fighter ensures that Sheena's special goes off during every combat, which is just amazing.

Passive C: Fortify Armor / etc.

Right now I have Fortify Armor, but I may change that to something that doesn't require such precise positioning. It will all depend upon her team composition.

Alternatively, something like Spd Ploy 3 (given Sheena's respectable Resistance), Threaten Spd 3, or Spd Smoke 3 could be useful too to help narrow the Spd gap that much more.

Sacred Seal: Spd/Atk Bond 3 / Spd/Res Bond 3 / etc.

Probably something that boosts Sheena's Spd or reduces the foe's Spd is what I want to go for here, though it is important to also be mindful that Sheena's attack power and defensive prowess remain intact as well.

45+33+22+36+33 basic
50+47+22+36+37 weapon (slaying axe)
50+52+22+41+42 ploy
53+55+25+44+45 flower/merge

Resolve combat as if foe suffered Def/Res-50%.
Unit recovers HP=half damage dealt.
in 5 hits instead if six with slaying
with vengeful: take a hit ->1
respond -> 2/3
second hit -> 4 (not neccessary)
second respond -> 5/6
average def:32 -> 52-16=36 damage-> 18 heal every defensive turn
works at both ranges

~Great Wall of Sheena~ (merged +10) [WIP]

Arena stall tank soaking one hit from powercreeped offense. DC helpful for both score and weakening enemy.

Thinking of taking Def Ploy as C and Renewal as seal for greater longevity, or Atk Ploy if Chills can't be obtained. Special Fighter may be fun as well.

This build takes large advantage of Sheena's incredible tanking capability. It's important to note that she's S supported with my L! Roy and that she's currently +5

Hack-o'-Lantern allows Sheena to keep safe from special abilities. This is essential to her survivability. Unlike other weapons that might be better for dmg output (ex: slaying axe), Hack-o'-Lantern fits perfectly since she is relatively slow rather other units, thus, this will help trigger big specials like Ignis and Glacies.

Ignis: with 46+ defense you will roast anyone that tris to stand a fight, even red foes.

(A) Distant Counter: this has no tremendous explanation, since she is a 1 movement unit, and DC allows to fight back from distance.

(B) Vengeful Fighter: BEST skill for this unit, since this skill will help her to trigger Ignis and Glacies as she will be fighting faster units.

(C) Attack Tactic: This is flexible, and I choose this skill because of my main team composition. You can try another one if you like.

(S) Close Defense: I like more Close than Distant Def, because it's more likely to fight melee high tier units rather than mage and bow units (that will probably get killed in 1 hit). You can switch this skill with DF combined with Glacies to maximize dmg.
