Leon

Weapon: Bow of Beauty (+EFF)

Assist: Reposition

Special: Bonfire / Moonbow

Passive A: Swift Sparrow / Atk/Spd Solo

Passive B: Lull Spd/Def

Passive C: Joint Hone Spd / Odd Spd Wave

Sacred Seal: Swift Sparrow / Flashing Blade

• While Leon's Speed is mediocre at best, it can improve drastically with some investment. Thanks to the Speed buff on his Bow of Beauty's special refine, an unmerged +SPD Leon can reach 48 Speed before buffs, while debuffing his opponent by -3 Speed due to his Lull skill. Merges and Dragonflower investment further improve his offensive prowess.
• Because his weapon has cooldown mitigation, Leon can choose whether he wants to utilize Moonbow, which he can trigger in a single combat even if his opponent does not retaliate, or Bonfire, which will hit harder, but be more difficult to utilize in a single fight.
• Due to Speed stacking, the followup denial on Bow of Beauty is more of a deterrent that protects him against units who use skills such as Quick Riposte or Vengeful Fighter.

Weapon: Brave Bow+ / Spendthrift Bow+

Assist: Reposition / Flexible

Special: Moonbow / Luna

Passive A: Death Blow 4 / Sturdy Impact

Passive B: Lull Atk/Def

Passive C: Def Smoke / Pulse Smoke

Sacred Seal: Death Blow / Heavy Blade

• Despite his refine, Leon still gets more mileage out of disregarding his poor Speed and focusing his Attack via the Brave Bow. With an +ATK IV, Leon reaches 37 Attack, which increases to 44 with the Brave Bow equipped, and hits over 50 with his skills all in play.
• Because he is so easy to merge, a +10 Leon with +10 Dragonflowers will reach 67x2 with this build, which vastly outstrips many of his other options.
• Leon is also one of the better users of the Spendthrift Bow for this reason: with his above-average Defense, combining Spendthrift Bow's -7 Attack debuff on his foe with Sturdy Impact's +10 Defense and Lull Attack's further -3 Atk Debuff, Leon essentially adds +20 Defensive Bulk on his initiations, making him very difficult to OHKO by a physical target. Furthermore, due to Sturdy Impact's followup denial, his target only has one opportunity to attack him in retaliation.
• The difference between the two builds is that the Brave Bow build trades defensive utility for raw offensive power, while his Spendthrift Bow build may not KO his target, but it also makes him exceptionally tanky.

Weapon: Bow of Beauty (+EFF)

Assist: Draw Back / Reposition

Special: Bonfire / Moonbow

Passive A: Close Foil / Close Counter / Steady Posture

Passive B: Lull Atk/Def / Vantage / Mystic Boost

Passive C: Pulse Smoke / Atk Smoke

Sacred Seal: Quick Riposte / Atk/Def Bond

• Since the Bow of Beauty's stat buff works in either phase, Leon can utilize a Close Counter build to be more flexible. He prefers Close Foil for the additional stats and his low Resistance makes him too vulnerable to dragons to want to bait them in the first place.
• Lull Atk/Def adds to this, increasing his bulk while also increasing the damage he does. Vantage is another option for his B slot, but be warned that Vantage and Bow of Beauty's effects are anti-synergistic. Leon only gets his stat buff above 50% HP and Vantage only works below 75% HP, giving him a very narrow window in which both effects will be active. It's generally better to keep his HP as high as possible through Defense stacking.
• Mystic Boost is a niche option for refilling his HP after every combat to keep him in range for his Bow of Beauty stat buffs.
• Pulse Smoke and Atk Smoke both help to mitigate the damage he takes, while Quick Riposte is needed in his S slot to ensure that he doubles in the Enemy Phase.
