Kinkou Jitte

Stats

Values as the League of Legends Wiki's item data lists them, for every mode; the data doesn't state their units.

Effects

• Between the Ribs (unique): You can now identify the Weakpoints of nearby enemy champions, marked as an arc around them and pointing towards a specific direction. Weakpoints on targets take 4 seconds to become exposed and linger for 11.25 seconds afterwards. Dealing damage while you are facing an exposed Weakpoint will consume it to deal bonus true damage equal to 3% (+ 3% per 100 AD) (+ 2% per 100 AP) of the target's maximum health and grant you 50 to 75 bonus movement speed for 1.5 seconds. Once a target's Weakpoint is consumed or expires, you identify a new Weakpoint on them.³

• Lillia's passive and Singed's poison can trigger Weakpoints while their damage continues as they move to the marked angle. Ahri's Q and an ability from Aurora can also hit from behind a target and trigger a Weakpoint.⁵⁶
• Kinkou Jitte damage can critically strike with Vulnerability.⁷⁸
• Fiora can use Parry with Kinkou Jitte against champions that repeatedly knock enemies airborne.⁹

• Zed's shadows cannot trigger Kinkou Jitte, whether it has one Weakpoint or all Weakpoints.¹⁰
• Some area-of-effect abilities can trigger Kinkou Jitte multiple times within a second.¹¹
• Kinkou Jitte's Weakpoint animation can show only one Weakpoint after the first one is broken, and the side it shows may not match the actual Weakpoints.¹²

• In the eight-teams-of-two format, Kinkou Jitte's Weakpoints sometimes appeared all at once, and they could be triggered from behind a target while the attacker was in front if an ability hit from behind.⁶
