Quick Answer for Patch 26.20

  1. Dashing

    Prismatic

    Your dash, leap, blink, or teleport Abilities gain 200 Ability Haste.

    Why on Kayn

    Reaping Slash (Q) is a dash, so it gains 200 Ability Haste and you can cast it far more often for damage and repositioning in fights.

  2. Outlaw's Grit

    Gold

    After using a Dash, Blink, or Teleport Ability you gain Armor and Magic Resist.

    Why on Kayn

    Every Reaping Slash (Q) is a dash, so you gain Armor and Magic Resist each time you dive in, helping you survive in melee range.

  3. Thread the Needle

    Gold

    Gain 15% Armor Penetration and Magic Penetration.

    Why on Kayn

    Reaping Slash (Q), Blade's Reach (W) and Umbral Trespass (R) deal physical damage, so the Armor Penetration raises your damage against armored targets.
