Rek'Sai generates Fury by Attacking and hitting with basic Abilities. She consumes this Fury while Burrowed to restore health.

Rek'Sai's next 3 basic attacks deal bonus Physical Damage to nearby enemies. While Burrowed, Rek'Sai launches a burst of void-charged earth that damages and reveals enemies hit.

Rek'Sai burrows into the ground, gaining new abilities and increased Move Speed. Her vision range is reduced and she cannot use basic attacks. While Burrowed, Rek'Sai may cast Unburrow to knock up and damage nearby enemies.

Rek'Sai bites her target, dealing physical damage, or bonus true damage if she has max Fury. While Burrowed, Rek'Sai creates a re-usable, long lasting tunnel. Enemies can destroy it by standing on top of either entrance.

Rek'Sai passively marks targets by damaging them. She can activate this ability to become briefly untargetable and lunge at a marked target for heavy damage based on their maximum health.
W Burrow / Un-burrowSome of their lockdown (airborne) ignores tenacity, so you dodge it; you can't cleanse or Merc' through it.
