Kha’Zix: The Voidreaver

Kha’Zix is a champion in League of Legends played in the Jungle, classified as an Assassin (legacy: Assassin). The Voidreaver uses Mana (327–1113 at max level) and deals Physical adaptive damage. Released September 27, 2012, last changed V25.24, patch V26.03. Kha’Zix embodies a simple but lethal concept: find someone alone, delete them before they can react. The Isolation mechanic is what separates Kha’Zix from every other assassin. While Zed needs a full combo, and Talon needs to wall-hop for setup, Kha’Zix just needs the enemy to be away from their allies – then Q deals effectively 378 base + 231% bonus AD on a 4-second cooldown. That’s roughly 800+ damage from a single Q at full build, every 2.2 seconds with evolved Q on isolated targets. No other ability in the game approaches this single-target DPS. His evolution system at levels 6, 11, and 16 lets you adapt mid-game: evolve Q for assassination power, E for resets and range, W for utility, or R for stealth plays. The “hunt or be hunted” mini-game against enemy Rengar also adds a unique competitive element.

📊 Base Statistics

💡 Unique Mechanic: Kha’Zix’s Isolation system is the core of everything he does. An enemy is considered Isolated when no allied champions, minions, or monsters are within ~325 units of them. A visible circle indicator appears around Isolated enemies from Kha’Zix’s perspective. Against Isolated targets: Q deals 110% increased damage (effectively 210% total), evolved Q CD is reduced by 45%, Unseen Threat passive and evolved W have enhanced effects. Isolation turns an ordinary skirmisher into the deadliest assassin in the game. At full build with 300 bAD: normal Q = 180 + 330 = 510 damage. Isolated Q = 378 + 693 = 1071 damage on a 2.2-second CD. That’s a basic ability hitting harder than most ultimates, spammable every 2 seconds. The strategic implication: Kha’Zix doesn’t want teamfights – he wants to catch people alone in the jungle, rotating between lanes, warding, farming side lanes. Every time an enemy is away from their team, Kha’Zix can kill them in under 2 seconds. This creates enormous map pressure: the enemy team has to group constantly or risk individual members being deleted.

🐛 Passive: Unseen Threat

INNATE: Gains Unseen Threat whenever the enemy loses sight of Kha’Zix or he activates Void Assault. Empowered next auto deals 17–150 (by level)(+50% bAD) bonus magic damage and slows by 25% for 2 seconds.

➡️ Key Mechanic: Unseen Threat procs from any vision loss – walking into a bush, R invisibility, or simply leaving enemy vision range. At level 18 with 300 bAD, the passive deals 150 + 150 = 300 bonus magic damage per proc. Since R can be cast 2–3 times (evolved), that’s 2–3 passive procs in a single fight. The 25% slow for 2 seconds also guarantees that your Q and follow-up autos land. Critically, Unseen Threat deals magic damage while the rest of Kha’Zix’s kit is physical – enemies stacking armor don’t fully mitigate your burst because ~300–600 of it bypasses armor entirely through magic damage passive procs.

⚔️ Q: Taste Their Fear

Cost: 20 Mana | CD: 4s | Cast: 0.25s | Range: 325 | Radius: 375

PASSIVE: Enemies are Isolated when no allies are within ~325 units. Q, Evolved Q, and Evolved W have special interactions against Isolated targets.

ACTIVE: Slashes target enemy dealing physical damage, increased by 110% against Isolated targets.

💡 Pro Tip: Evolved Q is the first evolution in 99% of games and for good reason. +50 range means Q reaches 375 and autos reach 175, making it significantly easier to land your core damage ability. The 45% CD reduction on Isolated targets is where it becomes broken: 4s base → 2.2s against isolated enemies. With ability haste, this drops below 2 seconds. You can Q an isolated target 3–4 times in a single fight, each dealing 1000+ damage at full build. That’s 3000–4000 damage from Q alone in under 6 seconds. No other basic ability in the game achieves this single-target output. In jungle clears, Q’s 20 mana cost and 4s CD means you can use it on every camp rotation – start every camp with Q for efficient clears.

🌀 W: Void Spike

Cost: 55/60/65/70/75 Mana | CD: 9s | Cast: 0.25s | Range: 1025 | Width: 140 | Speed: 1700

ACTIVE: Fires a spike bolt that explodes on first enemy hit, dealing physical damage to nearby enemies. Heals Kha’Zix if he’s within the explosion radius.

➡️ Key Mechanic: Void Spike’s heal is often overlooked but is critical for jungle sustain and mid-fight survival. Standing inside the explosion radius when it hits a camp or enemy heals 135 (+50% AP) at max rank – with no AP items that’s 135 per cast, significant when clearing. Evolved W transforms it into a wide 3-cone projectile with 40% slow (60% on Isolated) and 2-second reveal. The reveal is particularly strong: it prevents enemies from using bushes to drop your Unseen Threat passive, and the 60% Isolated slow makes it impossible for caught targets to escape before your Q combo finishes them. Evolved W is the most common second evolution after Q.

🦗 E: Leap

Cost: 50 Mana | CD: 20/18/16/14/12s | Cast: None | Range: 700 | Radius: 300

ACTIVE: Leaps to target location dealing physical damage upon arrival. Taste Their Fear can be cast during the dash.

💡 Pro Tip: Evolved E is what turns Kha’Zix from a single-target assassin into a teamfight reset machine. 900 range leap that resets on every champion kill/assist. In a teamfight: leap onto the squishiest target, Q (kill), E resets, leap onto the next target, Q (kill), E resets again. A fed Kha’Zix with evolved E chains kills like Katarina – each reset launches you 900 units across the fight to the next victim. The 900 range is also enormous for engaging: that’s almost Flash distance. E + Flash covers ~1200 units, letting you reach any backline carry from nearly any position. Critical tech: Q can be cast mid-E. This means you Q while airborne, dealing damage the instant you land. The enemy sees you leap and takes Q + E + auto damage simultaneously with zero reaction window.

🐛 R: Void Assault (Ultimate)

Cost: 100 Mana | CD: 100/85/70s | Cast: None

PASSIVE: Each rank allows evolving one ability, permanently enhancing it (2s cast channel).

ACTIVE: Becomes invisible for 1.25 seconds + 40% bonus MS. After 2 seconds of leaving invisibility, R can be recast once within 12 seconds (no additional cost).

➡️ Key Mechanic: R is deceptively powerful because of Unseen Threat interaction. Each R cast grants invisibility, which re-procs Unseen Threat when you exit. Base R: 2 casts = 2 passive procs = ~600 bonus magic damage. Evolved R: 3 casts = 3 passive procs = ~900 bonus magic damage + 3 separate 25% slow applications. The 40% MS during invisibility also lets you reposition mid-fight: R invisible, walk behind the target, appear with empowered auto + Q. The 2-second invisibility (evolved) is long enough to wait out key abilities – if the enemy uses a stun/root, R to become invisible, wait, then re-engage. The evolution system itself is the strategic layer: at levels 6, 11, and 16, you choose which ability to permanently enhance. Standard order: Q first (always) → E second (resets) → W or R third.

🧬 Evolution Priority Guide

🎯 Strategies and Gameplay Tips

Early Game (Levels 1-5) – Farm and Invade

• Strong Early Duelist: Kha’Zix is one of the strongest level 3 duelists in the jungle. Q deals massive single-target damage, and jungle monsters are always Isolated (alone at their camp). If the enemy jungler is someone weak early (Karthus, Evelynn, Amumu), invade them at their second buff. Catch them isolated at Red/Blue with Q + auto + W and they die before reaching 50% HP.
• Scuttler Control: Kha’Zix excels at scuttler fights because the river provides wide open spaces where enemies are often Isolated from minions and allies. Walk to scuttler spawn, wait in river bush for enemy jungler. When they start scuttler, jump on them with passive auto (slow) + Q (Isolated bonus). Most junglers lose this fight.
• Gank Isolated Lanes: The ideal gank target is a solo laner pushing without nearby minions. Wait for the enemy to step away from their wave, then E + auto (passive slow) + Q for Isolated damage. Even if you don’t get the kill, chunking 60–70% HP from a gank forces a back and gives your laner advantage.

Mid Game (Levels 6-10) – Evolved Q Assassinations

• Evolved Q Power Spike: Level 6 with evolved Q is Kha’Zix’s most significant power spike. +50 range makes Q easier to land, and 45% CD reduction on isolated targets means Q is on a ~2.2-second cooldown. Find anyone alone in the jungle – support warding, ADC farming a side wave, mid laner rotating – and they die in 2–3 seconds. R invisibility → passive auto (slow) → Q → wait 2s → Q again = dead.
• Invade the Enemy Jungle: Kha’Zix with evolved Q owns the enemy jungle. Clear your camps, then cross into their territory. If you find the enemy jungler at a camp, they’re Isolated from everything (monsters don’t prevent Isolation). Engage with R passive auto → Q for massive Isolated damage. Most junglers can’t survive this burst.
• Ward Control Kills: Enemy supports routinely walk into river alone to place wards. These are free kills for Kha’Zix. Wait in a bush near common ward spots (dragon pit entrance, baron river, tribush). When the support walks by alone, they’re Isolated. E + Q + auto = dead in under 1.5 seconds. Supports typically have ~1500 HP at this stage – your Isolated Q combo deals more than that.

Late Game (Levels 11+) – Evolved E Resets

• Chain-Kill Potential: Level 11 with evolved E transforms teamfights. Jump onto a squishy target, Q (kill), E resets, immediately leap 900 units to the next target, Q (kill), E resets again. A fed Kha’Zix can chain 3–4 kills in rapid succession, leaping across the entire fight. This requires patience: wait for enemies to get low before engaging. Don’t be the first in – let your team chunk enemies to 50%, then leap in for the cleanup.
• Flank Positioning: Never group with your team before a fight. Instead, position on the flank or behind the enemy in fog of war. When the fight starts and the enemy ADC/mage steps forward, you’re already behind them. E onto them from the blind spot, Q for Isolated damage (they’re separated from their frontline), kill, E resets, continue. This positioning denies the enemy team the ability to peel for their carries.
• Objective Steals: Kha’Zix’s E + Smite combination is excellent for stealing Dragon/Baron. The 900 range evolved leap covers most of the pit wall. Jump in, Smite the objective, Q the enemy jungler (they’re often Isolated inside the pit from their team), and either kill them or R invisible to escape. The burst from E + Q + auto + Smite often outpaces the enemy jungler’s Smite timing.

❌ Common Mistakes and How to Avoid Them

• Fighting Non-Isolated Targets: Kha’Zix’s damage drops by over 50% against non-Isolated enemies. Q goes from 378 +231% bAD to 180 +110% bAD – that’s the difference between one-shotting and tickling. Never engage on someone standing next to their allies, minions, or monsters unless you’re just cleaning up a kill. If the Isolation indicator isn’t showing, don’t fight.
• Engaging First in Teamfights: Kha’Zix has 643 base HP and 32 base AR. Leaping into 5 enemies first = instant death regardless of how fed you are. Wait 3–5 seconds for the fight to start, let CC and burst fly, THEN engage on the lowest-HP/most-isolated target for the cleanup. Your role is cleanup assassin, not initiator.
• Wrong Evolution Order: Evolving E first (before Q) wastes your level 6 power spike. Q evolve gives 45% CD reduction on Isolated targets – that’s your primary damage amplifier. E resets don’t matter until you can actually kill targets fast enough to proc them. Always Q first, E second.
• Not Using R for Passive Resets: Each R cast resets Unseen Threat for another empowered auto. Using R only for escape wastes ~300–600 bonus magic damage per fight. Mid-combat: auto (passive) → Q → R invisible → reappear → auto (passive reset) → Q again. Two passive procs = ~600 extra magic damage the enemy can’t itemize against.

⚙️ Recommended Build and Itemization (53% WR)

Core Items

• Umbral Glaive: First item in the highest WR build. Lethality + AD + the unique ward-clearing passive. Kha’Zix thrives in darkness – Umbral Glaive destroys enemy wards with one auto, denying vision that would reveal your flanking positions. The lethality amplifies Q burst against squishy targets. Clearing wards also sets up future Isolation kills by removing the enemy’s ability to see you coming.
• Ionian Boots of Lucidity: Ability haste for lower Q cooldown (the ability you use every 2–4 seconds) + reduced R and E cooldowns. Flash haste from Ionian Boots is also valuable – Flash + E covers massive engage distance, and having Flash available more frequently means more assassination opportunities.
• Bastionbreaker: Lethality + armor pen component. Amplifies Q damage against targets building even small amounts of armor (Seeker’s Armguard, Plated Steelcaps). The combination of flat lethality + % penetration ensures your burst remains lethal throughout mid-game.

Scaling Items

• Edge of Night: Spell shield + lethality. The spell shield prevents one ability from interrupting your assassination combo. Jump on the ADC, their support throws a stun – Edge of Night absorbs it, and you complete the kill uninterrupted. Essential against CC-heavy teams.
• Serylda’s Grudge: % armor pen + slow on abilities. Late-game targets have more armor, and Serylda’s ensures your Q still shreds through it. The slow on Q also helps stick to targets who flash or dash away from the initial burst.
• Guardian Angel: Revive passive. After diving the backline for a kill with evolved E, dying, and reviving, your E cooldown has likely reset from the takedown. You revive and immediately leap out to safety. GA turns suicidal dive-plays into net-positive trades.

🔶 Runes

Primary – Inspiration:

• First Strike: Kha’Zix’s optimal keystone. Since you engage from invisibility (R) or fog of war (bush), you almost always hit first, triggering First Strike’s 9% bonus damage + gold generation on your entire combo. First Strike on an Isolated Q combo adds ~100–200 extra damage AND generates 50–100 gold per kill. Over a game, First Strike generates 500–1000 bonus gold, effectively giving you a free long sword worth of stats.
• Cash Back: Gold refund on item completion. Accelerates Kha’Zix’s item spikes when combined with First Strike gold generation.
• Triple Tonic: Free elixir at levels 3, 6, 14. Level 3 elixir gives early combat stats for invades. Level 6 elixir coincides with Q evolution for amplified assassination power.
• Cosmic Insight: Item + summoner spell haste. Lower Flash CD (more engages), lower Smite CD (more objective control), lower item active CDs.

Secondary – Domination:

• Sudden Impact: Lethality + magic pen after using E (Leap) or R (Void Assault). Since every assassination combo starts with E or R, Sudden Impact is always active during your burst window.
• Treasure Hunter: Gold from unique champion takedowns. Kha’Zix ganks and kills unique champions constantly through the early/mid game, stacking Treasure Hunter rapidly for accelerated item spikes.

⚔️ Counter Picks & Matchups

✅ Kha’Zix Counters (Strong Against)

1. Jayce / Zed (Squishy AD Junglers)

Why: Both are squishy melee/ranged champions who Kha’Zix out-duels in Isolation. In river and jungle encounters, they’re Isolated and Kha’Zix’s Q burst exceeds their damage output. Kha’Zix also clears faster than both, maintaining tempo advantage for invades and ganks.

2. Karthus

Why: Karthus is immobile and always Isolated while farming jungle camps. Kha’Zix can invade and kill him at any camp. R invisibility dodges Karthus’s Lay Waste (Q) poke, and E + Q burst deletes him before he can deal meaningful damage. Karthus’s Defile passive after death is also avoidable with E leap.

3. Evelynn

Why: Evelynn is squishy and weak pre-6. Kha’Zix invades and kills her at camps before she reaches level 6 camouflage. Even post-6, Kha’Zix’s Q burst one-shots Evelynn since she builds full AP with no HP. Umbral Glaive clears her control wards, denying her stealth-detection setup.

❌ Kha’Zix Countered By

1. Rammus

Why: Rammus stacks armor and returns physical damage through Spiked Shell. Kha’Zix’s entire kit is physical damage. Attacking Rammus literally kills yourself. His taunt (E) forces Kha’Zix to auto-attack him, taking reflected damage while being CC’d. Rammus’s Powerball also matches Kha’Zix’s mobility, preventing escapes. The worst possible matchup.

2. Naafiri

Why: Naafiri’s packmates prevent her from ever being Isolated. Her dogs count as allies, meaning Kha’Zix’s Q never triggers the 110% bonus damage. Without Isolation, Kha’Zix’s burst is mediocre. Naafiri also out-duels base Kha’Zix in early skirmishes through her packmate DPS. A fundamentally unfavorable matchup by design.

3. Fiddlesticks

Why: Fiddlesticks’ fear shuts down Kha’Zix’s combo sequence. Kha’Zix needs to E in, auto, Q in rapid succession. Fear interrupts this chain. Fiddle’s passive (Dread) also fears from fog of war – exactly where Kha’Zix operates. Fiddle’s drain healing outsustains Kha’Zix’s burst if the kill isn’t instant, and Crowstorm creates zones where Kha’Zix can’t safely enter.

FAQ

Q: What makes a target Isolated?

A: An enemy is Isolated when no allied champions, minions, or monsters are within approximately 325 units. You see a visual circle indicator around Isolated targets. Jungle monsters are always Isolated at their camps. Champions walking alone in river, jungle, or side lanes are Isolated. In teamfights, backline carries standing 325+ units from their frontline are Isolated. Minion waves prevent Isolation in lane.

Q: What’s the optimal evolution order?

A: Standard: Q (level 6) → E (level 11) → W or R (level 16). Q first is non-negotiable – 45% CD on Isolated targets doubles your DPS. E second for reset-chaining in teamfights. Third is flexible: W evolve for slow/reveal utility in teamfights, R evolve for extended stealth plays and 3 passive procs. Against squishy teams, R third for pure assassination. Against tanks/bruisers, W third for kiting utility.

Q: Is Kha’Zix good in teamfights?

A: Not as an initiator, but incredible as a cleanup assassin. Wait for the fight to start, let enemies use their CC and get chunked to 50–60% HP, THEN leap in with evolved E. Kill the lowest target, E resets, leap to the next, repeat. A fed Kha’Zix can chain 3–4 kills in rapid succession. The key is patience – going in too early means dying without getting resets.

Q: How does the Kha’Zix vs Rengar event work?A: When both Kha’Zix and Rengar are in the same game and both reach level 16, a special “Hunt” event triggers. If Kha’Zix kills Rengar (or assists), he gains a 4th evolution point – allowing him to evolve ALL four abilities. If Rengar wins, he upgrades his Bonetooth Necklace. This is a lore-based mini-game that can significantly impact late-game power.
