I'll cut you down with this very blade!


Sterne Leonis is one of the main characters and a summonable unit in War of the Visions: Final Fantasy Brave Exvius. He is one of the two princes of Leonis and the younger twin brother of Mont Leonis.

Although willing to prove himself in battle and with the skill to do so, his father always holds Sterne back while bringing Mont with him. Despite loving his older brother, this preferential treatment strains Sterne's relationship with his family. Witnessing Oelde's questionable methods and familial detachment, Sterne grows to hate his father, driving him on a dark path, becoming one of the two main antagonists (alongside Muraga) of season one.

Ultimately he would live up to his moniker of Fated Prince, as his actions put him in conflict with his family, culminating in a decisive battle to determine the course of Leonis.



Sterne is a fair-skinned young man with short black hair, contrasting with Mont and his parents' blond hair. He wears his signature Lion Armor, a crimson protective gear with the Leonis symbol on the chest. He wears bulbous red clothing underneath, armored gloves and darker pants and small armored boots. He dons a long black cape colored red underneath, and with darkened fur over his back and shoulders. He wields a long blade with a distinct cross-shaped hilt.

In his Knight of Ruin persona, Sterne wears a golden suit of armor that nearly covers his entire body. The armor and his sword are wrapped in chains, and he dons multiple black capes, and covers his eyes with a golden mask.


In contrast to Mont, Sterne is committed to enter the frontlines and prove his mettle. Recognized by many for his skill, he is confident in his abilities, which overshadow Mont's, although he respects his older brother and believes in him and his potential. Sterne feels inferior when his father never allows him to set foot in battle to preserve the Leonis royal bloodline. Thus Sterne has a strained relationship with him, at times resulting in disobedience as Kitone is tasked with keeping him in check.

Sterne's ties with his father hit rock bottom when he realizes how willing King Oelde is to sacrifice Helena, and even him, to preserve the royal bloodline. Feeling abandoned, Sterne grows to hate Oelde and vows to kill him. His disgust runs deep enough that he allies with his homeland's enemy, Muraga Fennes, and accepts an enchanted armor gifted by Sadali Crysthea. This armor's property is to amplify the wearer's armor, transforming it into strength, but also makes it hard for the wearer to remain in control of their actions while feeling strong hatred. Wearing this armor, Sterne became more ruthless, and now tries to kill anybody he deems an obstacle, including the slaughter of civilians just for sheltering Oelde. Nevertheless, he is still capable of holding back against familiar faces he holds no grudge against and spares some of his former comrades when captured because they were neither a threat nor was he interested in them. While still respecting and holding affection for Mont, he is more than ready to kill him too if needed to terminate Oelde.

Following his final clash with Oelde, Sterne realizes that his father never acted out of spite, but out of necessity, and that everything was fated to occur. Now too far along the path he chose, Sterne believes there is no coming back, and is committed to settle things once and for all with his older brother. Sterne reveals he enjoyed fighting alongside Mont, something he desired before their separation, but ultimately concludes there is no other way for him than follow his fate and fight against his brother.


Early life[]

Sterne is the younger twin prince to Oelde and Helena. The birth of the two princes elated the Leonis king, as he long sought to continue and protect the royal bloodline. As they grew up, Sterne's talent for combat became apparent, while his older brother was less successful. The two nonetheless enjoyed an amicable relationship, and Sterne—along many others—realized Mont's hidden potential. Sterne was trained by Owe, a wandering samurai who saw himself in the younger prince, while leaving Mont aside, believing the older twin could achieve better results by awakening his dormant talents by himself. Sterne was skilled enough to be granted leadership of his own division, Fortem.

While Sterne's fighting prowess was said to even best Oelde's, and his achievements were numerous, the Leonis King was reluctant to send him to the battlefield, committed to preserving at least one of his sons, often taking Mont along while leaving Sterne distraught. Kitone, a shinobi under their care, was left to monitor Sterne, which began to sow distrust and sour their relationship.

Event story[]

The Admirable Prince[]

Sterne was famous in Ardra for his skill with the blade and his good looks. The Paladin Nasha, who had rejected the marriage arranged by her parents, left her village to enlist in Fortem and win the prince's heart. The inexperienced Monk, Etre, also sought Sterne and met Yerma, a wandering viking, looking for a man of greater strength than hers. Listening to Etre's story, Yerma became interested in Sterne and the two tried to enlist in Fortem. They were met by Lilyth, commander of the Caelum unit who tasked them to go to a den of skeletons and deal with the monsters. The two women met with Nasha who was also given the same task, but her poor sense of direction kept her going in circles. Though the three dealt with the threat, they believed their achievement to be insufficient, and sought a bigger trophy to display. They set their sights on the border with Fennes, hoping to prove themselves against the kingdom's foe. The trio defeats a group of Fennes soldiers and meets with Mont who becomes convinced them to be competent enough. Upon returning to the Leonis Castle, Mont reports their achievement to Lilyth, and later to Sterne. Believing Mont's endorsement, he allows the trio to enlist.

The trio attempt cook desserts for Sterne,[1] although the results of this endeavor are not known.


Sterne Leonis[]

The younger twin born to King Oelde and Queen Helena of Leonis. He has inherited his father's skill with a sword, and there are many who hope that he succeed the throne, rather than his brother. Because he was forbidden from going to battle, a confrontation with Oelde is becoming inevitable.

Character description

Sterne Leonis is a UR-rarity unit of the Dark element whose main job is Soldier, while his sub jobs are Dragoon and Ninja. He can equip the following items: Greatsword, Helm, Armor, Accessory. His unit cost is 80.

His Master Ability increases his Critical Damage by 25. His limit burst is Fatal Fang, which deals Dmg (L) to target & raises Dmg according to amount of own HP lost.

Sterne is a powerful unit who shines in offensive. He is develops great ATK power and Agi/Luck through his Soldier and Ninja passive abilities and can buff his ATK with certain skills and increase his accuracy and critical hit rate, further maximizing his offensive potential. Sterne is typically used with his Ninja subset because of its array of ranged abilities and other more useful buffs when compared to either his Soldier/Dragoon sets. Sterne can be a competent tank destroyer, as his Drain Force ability lacks element and type, bypassing resistances. Sterne is hampered by his lack of bulk, and although a powerful fighter with decent agility and attack power, he is not made to last when compared to other units. Being a Dark Elemental unit, he competes with more popular Dark units for Awakening Resources.

His EX Job grants him larger boosts to his ATK, Luck and Dex, thus further increasing his damage potential and critical hit chance. Hazard Form's upgrade now provides Defense Penetration and Hazard Break has larger damage modifiers. Coupled with Calamity Hazard, which decreases Slash resistance, gives Sterne a hard focus on greater damage, although his vulnerabilities remain.

Armor with a lion design that represents the Leonis royal family. The elaborate and imposing decorations embody the fierce intention to carry on the royal bloodline. For a young prince seeking military distinction, this cold armor suppresses his craving to surge into battle.

Lion Armor description

His Trust Master Reward is the Lion Armor armor, which bestows HP +434, DEF +8, EVA +6 and the Wall of Field ability, which raises own Area Attack Res for 3 turns.

Sterne (Knight of Ruin)[]

Sterne, clad in the golden armor bestowed by founder of the Church of the Crystal, Sadali. Containing a hidden power, this sinister armor amplifies Sterne's hatred for his father, Oelde. When enraged, it becomes almost impossible for him to distinguish friend from foe.

Character description

Sterne (Knight of Ruin) is a UR-rarity unit of the Dark element whose main job is Knight of Ruin, while his sub jobs are Samurai and Assassin. He can equip the following items: Greatsword, Helm, Armor, Accessory. His unit cost is 100.

His Master Ability increases his own DEF Piercing Rate by 20 and Slash Attack by 10. His limit burst is Destructive Fang, which deals Dmg (L) to target & absorbs Dmg dealt.

Sterne's Knight of Ruin variant is a powerful offensive unit with a focus on increasing his ATK through passives and buffs, and is adept at decreasing or ignoring DEF for bigger damage. He specializes in increased damage output towards Light elemental foes with Catastrophe. His Desperation passive bestows him a massive ATK bonus at the cost of lowering his resistance to all attack types. Mighty Break provides him an AP cheap ability to easily deal damage due to its massive 5-tile range with ATK debuff added as well. His strongest ability, Hazard Crusher, is devastatingly powerful with large area of effect, which debuffs the DEF of anybody affected before inflicting damage, useful for destroying groups of enemies. Double Attack makes him useful against foes with massive HP, as it allows him to build chains or deal higher damage than otherwise permitted under damage cap.

His Samurai sub job provides alternate attack methods and evasion boosts through buffs, passive and reaction abilities. His Assassin sub job helps him inflict poison or paralysis onto foes, while also granting him DEF reduction when attacking from the back, and additional evasion bonuses.

When compared to his normal version, the Knight of Ruin variant is overall much bulkier but has less ATK, although he compensates with his DEF-ignoring ability. Normal Sterne is faster, although Knight of Ruin can be more evasive and builds AP much easier. Due to being a 100 cost unit, he has half the chances of a regular UR unit from being summoned, and his shards used to be twice as expensive to purchase until an update that unified shard costs for all UR-rarity units. Although Knight of Ruin Sterne doesn't completely invalidate his original, it fixes many weaknesses and is more versatile for both general and PvP content use, although both have their niches.

A nefarious set of armor created by Sadali using the power of the Crystals. If one feels hatred while donning this armor, their mind will be consumed by that feeling and nothing else, causing them to behave wildly. The mask absorbs and amplifies these hateful emotions while the armor converts them into power.

Accursed Armor description

His Trust Master Reward is the Mask accessory, which bestows HP +444, DEF +10, CRT +12 and the Never-Ending Enmity ability, which raises own Unit Attack Res for 3 turns.

Vision cards[]

Birth of New Life

Birth of New Life.

On that day, all of Leonis was enveloped in cheers of joy, for the king's long-awaited child—two children, in fact—had been born. The cheers were all the louder as this also meant the birth of the prince who would one day reign over the land. Amidst the citizens' cheering voices—echoing so loud they shook the very walls of the castle—those close to the king whispered their concerns that twins would lead only to strife over who would ascend the throne. However, King Oelde laughed them away, confident that having twins would ensure the continuation of the royal bloodline. Though typically a brazen-faced king, on this day alone his smile would not fade. Queen Helena was overjoyed as well, but no one could be happier at the birth of these boys than Oelde himself.

"It's obviously chocolate, is it not?"
"Uh, really? Wow... It smells intense... You sure something didn't go wrong here, Yerma?"
"Intense is right. This isn't just chocolate; it's a soup full of delicious ingredients. When Lord Sterne drinks this he'll surely... Hehehe."
"More like his life will be in danger if he drinks this! We have to stop her, Nasha!"

A Year's Journey

A Year's Journey.

It was exactly this time last year. Father had ordered me to fell the bombs that had appeared in the outskirts of our territory. Ramada was kind enough to join me, knowing my dislike for battle, but having Sterne there with me was heartening above all else. The ring was given to me to keep me safe, but at the time I truly thought I would have no need for it.
...So much has happened since then. I could have never imagined the things that would befall Father, Mother, and Sterne. And there will surely be even more hardship to come. But I will continue on the path I believe to be right. I shall do naught but protect everyone I can and restore peace to these lands.

Becoming Stronger Than Anyone Else

Becoming Stronger Than Anyone Else.

Soldiers across the land fear the devilish swordsman known as Sir Owe. Leonis's ability to remain steadfast while surrounded by larger territories is due in no small part to Owe's countless military exploits. It was thus an easy choice for King Oelde to appoint him as the princes' sword instructor. The princes were polar opposites in both personality and swordsmanship, and Owe saw more of his past self in Sterne—a young man overeager to demonstrate his father's gallantry. He saw great talent slumbering in Mont as well, but he knew that only Mont himself could draw it out. Sterne is both motivated and astute, and he masters Owe's techniques with the same precision that Owe himself had. Though Owe saw Sterne's overly rapid growth causing rifts among the royal family, he turned a blind eye and chose instead to love Sterne as his disciple.
