Key stats worth increasing through nature if possible.
Complementary stats that matter, but not to the point of picking them over key stats for nature increase.
Relatively worthless stat that can safely be decreased through nature.

A Speed-increasing nature places her above all neutral units other than Lon'qu. She will rarely be placed in a position where she could be double-attacked without Swordbreaker, Quick Riposte or a significant boost from Speed-boosting buffs, spurs and A-passives. An Attack-increasing nature allows her to more easily kill enemies on the first or second swing of her attack. It is most useful for Lucina with Desperation and/or a Brave Sword+ where an Attack-increasing nature can mean an extra 6-12 points of damage on her attack.

A Resist-decreasing nature is preferred because her HP acts as a buffer for both physical and magical sources of damage, and she is not built for repeat attacks. Resist is the better option over defense because she will rarely take magical damage from a melee exchange, so her Defense will be more useful in many of her engagements. Three Resist will rarely save her from anything she is not supposed to survive, so it is the most logical choice in decreasing.

Skill Sets
I'm From The Future (Life and Death+ Desperation)
Falchion A Life and Death 3
Ardent Sacrifice B Desperation 3
Moonbow C Threaten Def 3

Show Explanation/Analysis
  • Preferred Nature: +Attack or +Speed/ -Resist or -Defense
  • Weapon: Falchion
  • Support Skill: Ardent Sacrifice / Reciprocal Aid
  • Special: Moonbow / Luna / Draconic Aura
  • A Slot: Life and Death 3 / Fury 3 / Death Blow 3
  • B Slot: Desperation 3
  • C Slot: Threaten Def 3 / Varies on team
  • Sacred Seal: ATK +1

Coming from a desperate future where everyone experiences both life and death everyday, she comes equipped to change history. Pushing her offensive powers to her limit by sacrificing her defense and resist, she is able to double-attack and ORKO more than three-fifths of the entire roster. With an added +4 ATK/SPD buff, a neutral Lucina is capable of KOing every non-blue unit aside from Swordbreakers and more than half of the blue units. She can secure even more ORKOs with Threaten Def taken into consideration against melee units and with a Speed/Attack-increasing nature.

Ardent Sacrifice and Reciprocal Aid can be used to help keep Desperation active while supporting her team. Moonbow is popular due to its low cooldown and Lucina's already high damage potential only needing a small assist occasionally. Luna can help with high defense neutral enemies or tough blue units. Draconic Aura is also a good alternative due to Lucina's high ATK rating. Fury 3 retains some of Lucina's offensive potential while also increasing her overall bulk and adding a second way to trigger Desperation. Death Blow 3 is a good option for a Speed-increasing nature to increase damage while maintaining some bulk.

Father Taught Me How To Defend Myself (Fury + Vantage)
Falchion A Fury 3
Reciprocal Aid B Vantage 3
Luna C Threaten Def 3

Show Explanation/Analysis
  • Preferred Nature: +Attack/ -Resist or -Defense
  • Weapon: Falchion
  • Support Skill: Reciprocal Aid / Reposition / Ardent Sacrifice
  • Special: Luna / Draconic Aura
  • A Slot: Fury 3 / Distant Counter / Defiant Atk 3
  • B Slot: Vantage 3
  • C Slot: Threaten Def 3 / Varies on team
  • Sacred Seal: ATK +1

Lucina can effectively weaken or kill a unit and have Luna or Draconic Aura charged up to be used with Vantage on a new enemy or the weakened enemy. Fury allows her to increase her relative bulk in a single exchange while bringing her closer to Vantage range. Distant Counter can be used to bait mages to their doom with a charged Luna/Draconic Aura coming from a distance or a full HP Lucina double-attacking them and setting up for her next victim. Threaten Def 3 helps support her endeavor to "kill units before they can kill her." Her native ability of Defiant Atk 3 can be useful, but take care when attempting to bring Lucina below 50% HP. Reciprocal Aid is great for health management especially with Falchion's regen. Reposition can be used as an alternative to help with positioning shenanigans and supporting teammates. Ardent Sacrifice can be used to offer a small heal to her allies while placing her inside Vantage range.

Hana's Protege (Brave Sword + Life and Death + Desperation)
Brave Sword+ A Life and Death 3
Ardent Sacrifice B Desperation 3
Luna C Threaten Spd 3

Show Explanation/Analysis
  • Preferred Nature: +Attack or +Speed / -Resist or -Defense
  • Weapon: Brave Sword+
  • Support Skill: Ardent Sacrifice / Reciprocal Aid
  • Special: Luna
  • A Slot: Life and Death 3 / Swift Sparrow 2
  • B Slot: Desperation 3
  • C Slot: Threaten Spd 3 / Threaten Def 3 / Varies on team
  • Sacred Seal: SPD +1

Lucina can take a page from Hana's book and run a pretty sweet Quad-Lucina setup. With Life and Death being used to compensate for her speed loss, she is able to maintain a great speed level while wielding the Brave Sword+. Upon reaching Desperation range, she will be able to achieve four attacks against most units before allowing the enemy to retaliate (if they are still breathing by that point). While increasing her damage potential against most units tremendously, units with high Defense may be able to handle Lucina's Brave Sword a little more easily than her Falchion. Also, Dragons will no longer take bonus damage from Lucina. Swift Sparrow 2 will give Lucina a lot of the benefits of Life and Death 3 while maintaining her defenses. Threaten Spd is used to compensate for her speed loss, but Threaten Def can also be used to increase her damage output by 10 to 20 points of damage. The biggest drawback of this build is the cost it takes to complete it, and Lucina can only be pulled as a Five Star, so she will have to train for a while to equip all these inherited skills.

  • Fantastic offense
  • Legendary weapon with bonus effects


  • Weak defenses
  • Lot of competition from other sword users

Lucina sets herself apart from other sword users as a one of the fastest and strongest attackers in the game with low defense and resist to balance out her incredibly powerful presence.  Her unique weapon improves her match-ups and superficially improves her defenses. Once she is on a roll, it is hard to stop her with anything short of an Effie or Ephraim.

  • Falchion
    • Unique weapon that increases damage against Dragons by 50%.
    • Heals her for 10 HP every 3 turns; helps repair her low defense and resist by healing her periodically.
    • Highest Mt on a sword.
  • High Attack
    • Sixth highest in the game.  Third highest among red units.
    • Able to OHKO many of the dragons and avoid taking any damage from them.
  • High Speed
    • Fourth highest in the game.  Third highest among red units. 
    • Improves her defense by preventing double attacks against every character in the game before abilities are considered.
    • Combined with her high attack, she can ORKO many units in the game.
  • Above Average HP
    • Tenth highest in the game.  Sixth highest among red units. 
    • Combined with her high speed, gives her the ability to absorb at least a single attack from most sources of damage.
  • Average Defense
    • At a rating of 25, her defense aligns with the bottom half of the roster.
    • Susceptible to brave weapons such as Cherche with a Brave Axe+.
  • Low Resistance
    • Sixth lowest in the game.  Fourth lowest among red units.
    • Mitigated by her high speed avoiding double attacks.
    • Can be OHKO'd by blue magic users.
  • Other Competition
    • Faces fierce competition from other sword users that offer other benefits such as Ryoma and Ike who have Distant Counter attached on their weapons or Alm, Marth and Chrom who also use their own Falchion.

Lucina is an exceptional sword unit with high attack and equally impressive speed.  She will double-attack most units in the game and kill most non-blue units in one attack round.  Her high speed and decent HP compensates for her low defenses and allow her to take at least one attack from most units before needing to regen back HP (or take advantage of a Desperation/Vantage build).

Lucina has to walk a fine line between life and death, pun intended, as she balances between incredible damage-dealing and heavy damage-absorption.  If you are a fan of wielding Desperation-Blade mages that prance around the battlefield with 1-5 HP, then you could enjoy Lucina and her melee-range embodiment of that playstyle.  To demonstrate her fragility with the most common physical green unit, attacking a bulky Hector with a full HP Lucina can end up with a failure to KO him and, as a result, be ORKO back with Hector's Bonfire.

Team Options

Lucina adores teammates that can buff up her offensive and defensive potential at the same time allowing her to maximize the number of ORKOs while increasing her chance of survival between enemy exchanges:

  • Ephraim (Is protected by Lucina against opposing green units)
  • Eirika (More effective at baiting green mages and can duel sword units with Swordbreaker allowing Lucina to worry about other units)

Desperation Lucina appreciates Dancer/Singer support to continue the assault or to reposition out of damage range:

  • Azura (Baits green units to her for Lucina)
  • Ninian (Decent bulk and can bait green units for Lucina)
  • Olivia (With a Ruby Sword+, can deal with Hector and baiting green mages)

Units that can handle killing and/or being attacked by all primary threats to Lucina:

Units that can effectively bait enemies for Lucina to kill:

  • Effie (Handles attacks from her color disadvantage and threatens to KO any enemies that get close to her)
  • Linde (Baits green units effectively while offering offensive supremacy, can use Ardent Sacrifice to heal Lucina)
  • Reinhardt (Very effective bait while offering offensive supremacy, give Lucina Reposition if using him though)
  • Robin (M) (Great at handling archers with his defense and Blarraven.  Effective at baiting green mages, but he cannot take a hit from them.)

Blue magical units are her number one threat:

  • Linde (Highest ATK on a blue mage)
  • Spring Lucina
  • Nowi (Threatened by Lucina's Falchion but be careful not to get hit first)
  • Reinhardt (Dire Thunder, on initiation, always attacks twice each attack round guaranteeing ORKO.Cavalry has more movement than Lucina)
  • Olwen (Dire Thunder, on initiation, always attacks twice each attack round guaranteeing ORKO.Cavalry has more movement than Lucina)
  • Ursula (Cavalry has more movement than Lucina)
  • Robin (M) (High defense allows him to combat Lucina effectively)

Blue physical units with high defense or high attack also cause her trouble:

  • Effie (Number 1 physical enemy of Lucina due to her triangle advantage, High HP/DEF, Wary Fighter, and the highest ATK in the game. Beware of Death Blow and Brave Lance+)
  • Ephraim (High defense and attack power but with low speed, so you could avoid a OHKO)
  • Azura (Sapphire Lance+ Increases her damage output to red units and decreases your damage output to her)
  • Lukas (Incredibly high defense with decent attack.  Low speed allows Lucina to avoid a double attack KO but beware of Quick Riposte)
  • Sharena (Good bulk with a weapon that lowers Lucina's ATK)

Colorless units with high ATK can cause her issues (especially powerful Archers with Brave Bow+)

High defense enemies with good retaliation damage:

  • Zephiel (Neutral color with Wary Fighter and high atk/def causes Lucina trouble)
  • Hector (Avoid initiating against him)
  • Gwendolyn (Low damage but can still hurt Lucina through her poor defenses)
  • Xander and Spring Xander(Especially dangerous with Cavalry buffs)
  • Hinata (High defense causes Lucina problems unless she uses Moonbow or Luna)

Aside from units, Lucina also suffers against several abilities:
