Kai

• His passive deals bonus damage whenever an attack or his 2 hits only one target, rewarding picking off isolated enemies.
• His 1 bounces between enemies, healing and speeding him up on hit while cutting its own cooldown.
• His demon-armor ultimate boosts his damage, speed, and damage block, letting him brawl through extended fights.

• Passive · Asura's Soul — When his basic attacks or his 2 hit only a single target, that hit deals 50% bonus damage.
• 1 · Whirling Blade — Throws a blade that bounces between multiple enemies, dealing physical damage and a slow (heavier on the first target); hitting an enemy heals him and cuts this skill's cooldown by 30%, plus grants bonus move speed and attack speed for 3 seconds.
• 2 · Blade Storm — Slashes twice in a direction, each hit dealing physical damage, with the second hit launching enemies for 1 second; also empowers his next basic into a charge for bonus physical damage. Passively, out of combat he regenerates HP/mana and gains bonus move speed.
• Ultimate · Undying Demon Armor — Summons demon armor that deals magic damage around him after 1 second, then empowers his attack, move speed, and damage block for 8 seconds while dealing repeated magic damage to nearby enemies.

Build 1: Boots of Resistance → Shadow Battleaxe → Glacial Storm → Grandmaster's Might → Phoenix's Eye → Endless Blade

Tip: A half-tank Kai stays aggressive without sacrificing survivability — Shadow Battleaxe and Glacial Storm cover early-to-mid sustain, and Grandmaster's Might turns his empowered basic into real burst.

Build 2: Boots of Resistance → Shadow Battleaxe → Grandmaster's Might → Endless Blade → Champion's Warplate → Famed Blade · Siming

Tip: Against an isolated enemy hero, his passive's damage spikes hard — a full-damage build can turn a single hit into a clean kill.

Inscriptions: Heritage, Hawkeye, Concealment

Tip: His 1's healing scales with physical damage, so Heritage adds attack power directly; Hawkeye's penetration boosts his late-game damage, and Concealment adds both attack power and move speed to chase targets down.
