Orianna Mid Build & Guide — Patch 16.12

Overview

Orianna is a control mage built around a single object: her Ball. Every ability except her passive sends, parks, or detonates the Ball, and her ultimate Command: Shockwave (R) is the highest-impact teamfight tool in the mid lane pool — a delayed pull that yanks every nearby enemy toward the Ball. She has no dash and short cast windows, which means her safety comes from Ball positioning (cover yourself with shields and zones) rather than from movement.

Her game plan is to control the wave with Command: Attack (Q), poke whoever steps inside her range with the same spell, and look for a multi-target R in any objective fight after level 6. Skill expression sits in where the Ball is right now: a Ball parked between you and the enemy is a poke setup, a Ball on your front line ally is a shield plus pre-loaded ult, and a Ball thrown into fog of war is a snap teamfight start.

Recommended Build

Starting items: Doran's Ring + 2 Health Potions. Skip Corrupting Potion unless the lane harasses you with auto-attacks heavily.

Core items (in order):

1. Luden's Echo — burst spike on first item with mana sustain so Q can be spammed for waveclear.
2. Sorcerer's Shoes — flat magic penetration to delete squishies (champions with low defenses, like ADCs and mages).
3. Rabadon's Deathcap — late-game AP multiplier; Orianna's R scales hard with raw AP.
4. Shadowflame — extra burst; the HP-threshold passive (extra damage when the target is below a low-HP soft cap) lines up with a finishing R.

Situational items:

• Zhonya's Hourglass — into divers and assassins (Zed, Diana, Talon, Akali). Stasis covers the gap between cast and impact of your R.
• Banshee's Veil — into single-target magic CC (Ahri charm, Lissandra R, Twisted Fate stun) that would cancel your R channel.
• Void Staff — the moment any priority target buys a Magic Resist item.
• Morellonomicon — into healing-stacking comps (Soraka mid, Vladimir, Dr. Mundo).

Boots: Sorcerer's Shoes is default. Ionian Boots of Lucidity are an option if your team needs faster R uptime as a teamfight starter.

Skill order: Max Q first (poke and waveclear), W second (slow zone), E last. Take a point in R at levels 6, 11, 16.

Runes: Primary Sorcery with Arcane Comet — your Q (Command: Attack) and W (Command: Dissonance) proc it repeatedly for steady poke damage across the laning phase. Pair it with Manaflow Band, Transcendence, and Scorch. Secondary Inspiration with Biscuit Delivery and Cosmic Insight. Stormraider's Surge is a valid swap into kite-heavy matchups (Yasuo, Zed) for the movement speed escape window.

Key matchups

• Yasuo / Yone: Wind Wall blocks Q and the Ball projectile entirely. Hold Q until they burn Wind Wall, then push with Q plus W. Don't let them get in auto range — passive ramping autos work both ways and they out-trade you up close.
• Zed: Vulnerable matchup. Track his W shadow placement; rush Zhonya's Hourglass after Luden's. Save Flash for his all-in at level 6, not for harassing him.
• Twisted Fate: Roam priority race. Push every wave with Q and ping mid danger when his R comes up at 6. If he picks gold card on you, Ball-shield (E) onto yourself to soak the auto-attack proc.
• Galio: Avoid stacking with allies in mid pre-6 (his W punishes grouped targets). Punish him while he is meleeing minions; he has no waveclear range to outpush you. Watch for his ult roams to side lanes after level 6.
• Lux: Even matchup, decided by team fights. Ranges match; out-trade her with passive auto-attack stacks if she misses Q since you scale better with the same item set.

Power spikes & win conditions

• Level 2: With Q plus W, you have the first proper trade pattern: Ball forward with Q, W on top to slow, walk up for two passive-stacked autos, walk back. Most lanes lose the level-2 race against this.
• Level 6: First Command: Shockwave. Even one-target R is a flash-equivalent reposition for your jungler's gank. Two-target R near the river is a free double kill.
• Luden's Echo completion (~ minute 12-14): Wave control flips. Push side lanes with Q, look for cross-map plays around Drake and Rift Herald with R.
• Rabadon's Deathcap online (~ minute 24-28): R into the back line one-shots squishies stacked together. Force objective fights here — this is your peak.

Common mistakes

• Throwing R as a single-target finisher on full HP. R is a setup ult, not a snipe. If two enemies are not within Ball radius, hold it; chain W then R when the cluster forms.
• Leaving the Ball on the wave during all-ins. When you're about to be engaged on, E to yourself for the shield and the Ball reposition. A Ball on a minion is a Ball doing nothing for you in a teamfight.
• Using passive ramping autos like a marksman. Two stacks already deal heavy damage; a third is great but stepping forward for a fourth often eats a counter-engage. Trade in three-auto windows, then back out.
• Forgetting Ball position before R. The Ball's current location, not Orianna's, is the R origin. If the Ball is on a backline ally, R lands on your team. Always Q or W the Ball forward before pressing R.
• Pushing without prio before Drake spawns. Orianna's waveclear is so strong that the temptation is to always shove. Sometimes hold the wave on your side so you arrive first to Drake — prio (priority — leaving the lane without losing minions or HP) matters more than chip damage.

Advanced tip

Master the Q-W self-cast combo around the Ball: cast Q to send the Ball forward, then immediately W at the Ball location. The Ball arrives, the W pulse triggers on it, and any enemy walking onto the Q endpoint takes Q damage plus W damage plus the slow at the same instant. This compresses your trade window from two casts down to one reaction frame — most opponents at low ranks cannot dodge both halves.
