• Kinkou Jitte, Blade Waltz, and Summoner's Revolution form a Fiora build.³
• Blade Waltz with Summoner's Revolution can fully heal Fiora and deal heavy damage to targets that are not tanks.⁴
• Kinkou Jitte, Blade Waltz, Summoner's Revolution, and Earthwake can one-shot opponents after Fiora uses R and Blade Waltz.⁵

• Kinkou Jitte shows four vitals like Fiora's ultimate, so an attack is guaranteed to proc at least one. The proc also grants movement speed and deals true damage.⁶

• Kinkou Jitte can sometimes proc from behind a target when an ability hits from that direction.⁷
