Xerath Mid Build & Guide — Patch 26.18

Overview

Xerath is an AP artillery mage — the longest-range caster in the game. His entire identity is "fire spells from a screen away and never be where the enemy can reach you." Every ability either covers the gap between him and the target or punishes the target for trying to close it. Q (Arcanopulse) charges up to a huge linear range that out-distances every farming pattern in mid lane. W (Eye of Destruction) drops a delayed area-of-effect zone with a stronger inner circle, the slow that holds enemies still for the rest of the combo. E (Shocking Orb) is a long, slow line skillshot that stuns based on how far it travelled — the further away you cast it, the longer the stun. R (Rite of the Arcane) is the global finisher: Xerath channels in place for up to 10 seconds and fires four artillery shots at rank 1, five at rank 2 and six at rank 3, from anywhere on the map.

His mid game plan: shove with Q-W to deny farm, then poke from outside the enemy's effective range every cooldown. Post-6 he becomes map presence — if a bot or top laner survives at 20% HP, your R lands across the map for the cleanup. The cost is fragility: no dash, no shield, no heal, and R roots him for the entire channel. Sit behind the wave, keep Flash up against assassins, and treat Zhonya's Hourglass as a build commitment, not a luxury.

Recommended Build

Starting items: Doran's Ring + 2 Health Potions. Doran's Ring stabilises mana for Q spam and adds AP — flat damage matters less than scaling for an artillery mage.

Core items (in order):

1. Luden's Echo — Xerath's defining first item. Burst-AOE on every damaging ability, plus 100 AP, 600 mana and 10 ability haste — the mana and the haste are what let Xerath hold Q-spam priority from minute 11. It carries no magic penetration: that comes later, from Sorcerer's Shoes and Shadowflame. The burst proc lets your Q one-shot a low-HP minion wave, freeing Xerath to poke instead of last-hit.
2. Sorcerer's Shoes — flat magic penetration aimed at the squishy backline you want R to finish.
3. Shadowflame — extra burst plus Cinderbloom: against a target below 40% of their maximum health, your magic and true damage critically strike for 120%, a flat +20% on the finisher. The 15 magic penetration in the stat block is unconditional and works from the moment you buy it. Lines up perfectly with R finishers cross-map.
4. Rabadon's Deathcap — late-game scaling multiplier: 130 AP in the slot, then Magical Opus raises your total ability power by 30%, the AP you already had included. Buy it third or fourth depending on whether the enemy team has already started stacking magic resist.

Situational items:

• Zhonya's Hourglass — into divers and assassins (Zed, Akali, Diana, Fizz). The 2.5-second stasis covers the exact window when your R channel finishes and you are still rooted to the ground; it also baits out the assassin's full burst on an invulnerable body. After the Patch 26.17 health cut this is not a fourth-item luxury any more: against a diver or an assassin, buy it straight after Luden's Echo.
• Banshee's Veil — into telegraphed magic CC (Ahri charm, Lissandra R, Twisted Fate gold card). The shield blocks the engage spell that would lock you for the entire fight.
• Morellonomicon — into heal-stacking comps (Soraka mid, Vladimir, Dr. Mundo, Aatrox top). The Grievous Wounds passive cuts their healing by 40% so your damage actually translates into kills.
• Void Staff — the moment any priority target finishes their first magic resist item. Stops one finished Magic Resist item from soft-countering your whole build.

Boots: Sorcerer's Shoes is default. Ionian Boots of Lucidity are acceptable if your team needs extra R uptime to chain global pressure on objective spawns.

Skill order: Max Q first (your main poke, lowest cooldown scaling), W second (more damage and slow on the AOE setup), E last. Take a point in R at levels 6, 11, and 16.

Runes: Primary Sorcery with Arcane Comet, Manaflow Band, Transcendence, Scorch. Secondary Inspiration with Biscuit Delivery and Cosmic Insight.

Key matchups

• Veigar: Stationary mage you out-range pre-6. Push him under tower with Q, charge Q from max range every time he steps up to last-hit, and recall before he hits level 6 — his cage threshold is the only moment the matchup flips. Buy Banshee's Veil if he survives lane.
• Zed: Diving threat with multiple gap-closers (a "gap-closer" is any dash, blink, or jump that crosses ground fast). Buy Zhonya's Hourglass as your second item after Luden's Echo. Never start an R channel when Zed has Living Shadow up — wait for him to commit it, then channel from safety. Pre-place E on his minimum-distance dash arc so the stun fires when he lands. Since 26.17 your health pool is 21 points smaller at every level, and Zed does not need much of an opening: Living Shadow (W) crosses half the lane in one button and Razor Shuriken (Q) lands through the wave, so channel R only once the shadow is already spent.
• Anivia: She out-scales but only if you let her farm safely. Push the wave constantly so her wall (a "wall" here is the Crystallize spell that splits the lane) keeps splitting your minions, not yours — and so she misses CS under tower. Roam to side lanes the moment your R comes up; Anivia has zero mobility to follow.
• Ahri: Range war but with charm. Save E for after she throws her Charm so the orb traveled long enough to land the full stun. Buy Banshee's Veil after Luden's Echo so her charm cannot disable your R channel.
• Yasuo: Wind Wall blocks both Q and E. Force him to wall an early Q-W poke, then commit the E stun on the cooldown window. Never start R channel while Wind Wall is up; it eats the first artillery shot. Treat this lane as "survive to teamfight" — your team's frontline pins him while you fire from behind.

Power spikes & win conditions

• Level 3 (Q-W-E): First spike. With one point in each ability, the full W → E (stun) → Q poke combo is online. This window is when you push for first poke advantage.
• Level 6 (R unlocked): First Rite of the Arcane is up. Look for a cross-map kill on a low-HP bot or top laner — four artillery shots at rank 1 into a recall window or a botched gank turn into a free shutdown bounty. Patch 26.17 is why this window is the play and the in-lane solo kill is not: base health dropped to 575 from 596 (21 fewer HP at every level, the per-level growth untouched), while Arcanopulse only lost 5 flat damage at every rank (75 ⇒ 70 at rank 1, the +90% AP ratio untouched). Your poke is worth what it was; your margin for error is not. Fire R at someone another lane has already opened up.
• Luden's Echo completion (~ minute 11-13): Wave control flips ("wave control" is who decides where the minion wave fights, you or the enemy laner). The burst proc lets a single Q clear the caster minions and chunk the enemy laner in the same cast. From here you should be the one shoving and pressuring.
• Rabadon's Deathcap online (~ minute 25-28): Full R rotation deletes squishies without magic resist. Force grouped objective fights here — Baron, Soul Drake, Elder.

Common mistakes

• Channeling Q without a W setup. Q is a slow projectile with a clear visual tell ("tell" = a visible warning the spell is starting): any half-attentive laner side-steps the raw cast. Drop W first so the enemy is slowed in place; or charge Q while they are last-hitting a frontline minion. Never fire a fully-charged Q on prediction alone.
• Standing still during R. Rite of the Arcane roots Xerath for the full channel. If you start it in the open with no team between you and the enemy, every assassin in the game prays for that moment. Channel from behind your frontline, behind a wall, or with Zhonya's Hourglass held in reserve.
• Wasting R on full-HP grouped enemies. R does most of its damage as the finisher on low-HP targets cross-map, not as the opener into a 5-man team. Six shots at rank 3 into a tank's HP bar is wasted potential; the same six into a Caitlyn at 30% across the map is a kill.
• Spamming E on cooldown. Shocking Orb's stun duration scales with travel distance. A close-range E barely stuns, while a max-range E locks the target long enough for a full Q + W combo. Save E for the long-distance angle, not for the reflex panic-button.
• Pushing without vision. Xerath has no escape — no dash, no blink, no shield. Pushing past the river without a ward in the enemy jungle is the single fastest way to feed an early gank. Place a Stealth Ward or Control Ward in tri-bush before every shove.

Advanced tip

Practice the shoot-around-the-wall E setup. Shocking Orb travels in a straight line and passes through brush and walls until it hits a target. When the enemy laner recalls into lane brush, mentally trace a line from your champion through the wall to where they will walk — then fire E along that line a fraction of a second before they reach the spot. Because the orb has traveled the long edge of its range, the stun is multi-second. Chain a max-charge Q along the same axis. A practiced Xerath turns this into a free 100-to-0 burst on a target who never saw the spell coming.
