How to itemise Yi Sun-shin and, more importantly, why each item earns its slot.

Overview

Why this build works on Yi Sun-shin

Yi Sun-shin relies heavily on weaving melee and ranged attacks to trigger Heavenly Vow, resetting Traceless while dealing guaranteed critical damage. Because his passive and ultimate, Mountain Shocker, scale directly with physical damage and critical stats, he requires a build that amplifies burst damage while giving him enough cooldown reduction to switch weapons constantly. This build addresses his need for sustained skill spamming and massive burst output. By combining true damage on skill usage with physical attack enhancements, Yi Sun-shin turns every weapon swap into a devastating sequence, while late-game armor penetration and defensive revival ensure he stays lethal in teamfights.

Item by item

Flame Hunter's Magic Boots

Early

Equipping Flame Hunter's Magic Boots grants crucial early cooldown reduction to spam Traceless and Blood Floods while speeding up jungle clear. The Hunter passive inflicts extra damage on jungle creeps, allowing Yi Sun-shin to secure early objectives like the Turtle much faster. This early mobility and faster rotation let him cross the map quickly, board the Turtle Ship at base, and gank lanes effectively during the opening minutes of the match.

In-game passive Unique Passive - Hunter: After dealing damage to a Creep, deal 25<2|lv 3> + True Damage to the target over 3s (damage is increased by 100% for non-Marksmen heroes).

Endless Battle is the core engine of Yi Sun-shin's kit. Since his passive, Heavenly Vow, encourages weaving skills between basic attacks, the Divine Justice passive triggers frequently, dealing true damage after casting Blood Floods or Traceless. The added cooldown reduction and lifesteal keep him healthy during jungle rotations, while the movement speed burst matches his hit-and-run assassin playstyle, transforming his weapon-swapping passive into a terrifying burst tool.

In-game passive Unique Passive - Divine Justice: After casting a skill, the next Basic Attack within 3s deals 60% Physical Attack as extra True Damage (1.5s cooldown).

Berserker's Fury magnifies Heavenly Vow's guaranteed critical strikes from weapon swapping. Because Mountain Shocker passively increases the damage of these enhanced attacks, the Doom passive triggers consistently, granting extra physical attack after every critical strike. This synergy dramatically elevates his melee and ranged burst potential, enabling Yi Sun-shin to shred squishy targets with a single weapon-swap combo after charging in with Traceless.

In-game passive Unique Passive - Doom: Critical strikes grant 5% extra Physical Attack for 2s.

Blade of Despair provides the ultimate physical attack power boost to maximize Blood Floods' hold damage and Mountain Shocker's global bombardment. The Despair passive activates when enemies fall low on health, significantly increasing physical attack right as Yi Sun-shin closes in with his glaive. This raw power upgrade turns his charged arrow shots into devastating snipe threats and ensures his global ultimate deals finishing damage across the map.

In-game passive Unique Passive - Despair: Dealing damage to non-Minion enemies below 50% HP increases Physical Attack by 25% for 2s (takes effect before the damage is dealt).

As enemy tanks and fighters build armor, Malefic Roar becomes essential for maintaining damage output. Its Armor Buster passive grants scaling physical penetration based on target defense, preventing enemy frontline heroes from ignoring Yi Sun-shin's attacks. With this item, both his enhanced basic attacks and the cannon waves from Mountain Shocker melt through heavily armored opponents, ensuring his late-game damage remains lethal in full teamfights.

In-game passive Unique Passive - Armor Buster: When attacking an enemy, gains 0.125% extra Physical Penetration for each point of the enemy's Physical Defense, capped at 40%.

Immortality

Situational

Because Yi Sun-shin often dashes directly into melee range using Traceless to trigger enhanced glaive attacks, he risks being focused down in late-game skirmishes. Immortality mitigates this vulnerability by providing a second chance at life through its Immortal revive passive. Upon revival, he gains a shield, giving him enough time to reset his cooldowns, board a nearby Turtle Ship, or dash away safely while casting Blood Floods.

In-game passive Unique Passive - Immortal: Revives 2.5s after death, gaining 16% Max HP and a 220-1200 shield (scales with level) that lasts 3s (210s cooldown).

Adapting the build

No build survives every draft. These are the situations where the order above should change.

When facing heavy physical armor stackers early

Prioritize purchasing Malefic Roar immediately after Berserker's Fury before building Blade of Despair. This ensures that the Armor Buster passive cuts through enemy defense early, allowing Yi Sun-shin's enhanced basic attacks from Heavenly Vow to retain high lethality against sturdy frontlines that build physical armor early in the match.

When being targeted aggressively in late-game teamfights

Delay Blade of Despair and buy Immortality fifth instead. Securing the Immortal revive passive gives Yi Sun-shin crucial survivability when diving into melee distance with Traceless. Resurrecting with a shield grants him the opportunity to reset skill cooldowns, board a Turtle Ship, and safely cast Blood Floods to turn fights around.
