Kez switches between his Kazurai Katana and Shodo Sai. He gains different attack capabilities and abilities based on the weapon equipped. The abilities level up together, and when an ability is used, the associated alternate weapon ability also goes on cooldown. Kez deals extra damage on the first Katana hit or ability after switching to Katana, and gains bonus speed after switching to Sai.

Kez slashes forward in a 800 distance line with his Katana, attacking enemies in an area and applying a brief 100% impact slow. After a short delay, the area is attacked again. Heroes take bonus damage.

Kez swings on a grappling hook towards the target unit or tree. When the grappling hook collides with the target, that unit has slowed movement speed. Upon reaching the enemy target, Kez lands an attack on them.

Katana attacks and abilities apply a stacking damage over time to enemies that deals a percentage of the original attack's damage as additional damage over time. Kez may activate the ability to impale the target with his attack, preventing them from moving or turning. The target's Katana debuff bursts, causing some of the stacks to deal damage instantly.

Kez enters into an uncontrollable state for 1 second, becoming invulnerable for 0.2s and receiving a basic dispel. If the cast completes successfully, Kez performs a series of deadly radial slashes around him that deal damage based on the max health of the target and heal Kez for a percentage of all damage dealt.
