Here are the notes and updates for League of Legends Patch 12.2

Welcome aboard, Zeri.

Zeri, the Spark of Zaun will make her debut in League of Legends in Patch 12.2.

Recommended Videos

Described as a “headstrong, spirited young woman from Zaun’s working-class” in her official biography, Zeri is an AD carry who runs fast, charges up, and shoots the bad guys on Summoner’s Rift.

The champion’s abilities include a laser that fires an electric pulse that slows and damages the first enemy hit, a dash that energizes her and enables her to vault over terrain, and a nova of electricity that damages nearby enemies and increases her damage, attack speed, and movement speed.

Patch 12.2, which is expected to hit the live servers on Thursday, Jan. 20, also features a myriad of balance chances for both champions and items. Janna and Tahm Kench are just two of the many champions receiving changes this week.

Here’s the full list of notes and updates for Patch 12.2.


[New] Zeri

Passive – Living Battery

  • Zeri gains movement speed whenever she receives a shield. When she damages an enemy shield, she absorbs its energy, shielding herself

 Q – Burst Fire

  • Passive  Zeri’s basic attack deals magic damage, scales with AP, and is treated as an ability. Moving and casting Burst Fire stores up energy in Zeri’s Sparkpack. When fully charged, her next basic attack will slow and deal bonus damage
  • Active – Burst Fire shoots a burst of seven rounds that deal physical damage to the first enemy hit

W – Ultrashock Laser

  • Zeri fires an electric pulse that slows and damages the first enemy hit. If the pulse hits a wall, it fires a long-range laser from the point of impact

E – Spark Surge

  • Zeri dashes a short distance and energizes her next three casts of Burst Fire, causing them to pierce through enemies. She’ll vault over or grind along any terrain she dashes into, depending on the angle. Hitting a champion with an attack or ability reduces Spark Surge’s cooldown

R – Lightning Crash

  • Zeri discharges a nova of electricity, damaging nearby enemies, and overcharges herself for a moderate duration. While overcharged, Zeri gains increased damage, attack speed, and movement speed. Attacking enemy champions refreshes the overcharge duration and adds another stack of movement speed. While overcharged, Burst Fire’s damage concentrates into a faster triple shot that chains lightning between enemies
