    8% of damage taken contributes to damage dealt.

Rek'Sai enables

  • Knock Up

    Briefly lifts the target into the air, interrupting their action. Set-17 sources include the Fizz and Rhaast carries, the frontliners Blitzcrank, Rek'Sai, Aatrox, Meepsie, and Nunu, and Samira herself — both via her active ("Jump and Jive") and the passive that triggers off any ally-applied knock-up.

  • Heal

    Restores Health to a unit, capped at maximum HP.

Rek'Sai scales with

  • Max Health

    Grants the unit additional maximum HP, either flat (like +150 Health) or percentage (like +6% max Health). It comes up whenever you stack Giant's Belt items, pick health-boost augments such as Yasuo's Golden Hex or Giant and Mighty, or play Cho'Gath, whose cast permanently raises his own max Health every time he eats an enemy. For the cross-round permanent stat-stacks angle specifically, see the dedicated permanent stat-stacks page.

  • Ability Power

    Scales with Ability Power (AP). Champions and effects flagged as AP-scaling get bigger damage, healing, or shield values when the holder stacks AP from items like Jeweled Gauntlet, Rabadon's Deathcap, and Nashor's Tooth, or from trait bonuses.
