Yuumi’s League of Legends rework: release date, new abilities & more

Complete guide to Yuumi’s reworked abilities with strategic insights for optimal gameplay

Yuumi’s Controversial History and Rework Context

The long-awaited Yuumi rework arrives with League of Legends patch 13.5, completely transforming one of the game’s most debated support champions. This comprehensive guide breaks down every ability change and provides strategic insights for mastering the new mechanics.

After extensive community feedback and balance struggles, Yuumi’s complete kit overhaul finally debuts on patch 13.5. The rework addresses fundamental design issues while maintaining her signature attachment gameplay with significant functional improvements.

Yuumi has consistently ranked among League’s most polarizing champions since her introduction. While dedicated mains appreciate her unique playstyle, widespread frustration emerged from her perceived low-skill impact in professional and casual play alike. This division reached dramatic levels with audiences actively booing professional teams that selected her in competitive matches.

Her dominance in professional competitions spanned over a year, forcing Riot’s balance team to implement severe nerfs that dropped her viability significantly. These adjustments cratered her win rate to approximately 38% at the lowest point, while player selection rates declined sharply following the changes.

The comprehensive rework aims to restore Yuumi’s competitive viability while addressing core design concerns. However, questions remain about whether these changes adequately resolve her most problematic gameplay elements, particularly regarding skill expression and counterplay opportunities.

Base Stat Changes and Rework Overview

Yuumi’s updated kit maintains familiar structural elements while implementing substantial functional modifications. The redesign emphasizes healing capabilities and defensive support over her previously excessive damage output. Notably, her E ability transitions from direct healing to shielding, with healing redistributed throughout other ability components.

Riot Games reaffirmed their commitment to Yuumi as an accessible champion for newcomers by reducing her Blue Essence cost to 450. This pricing adjustment ensures easier acquisition for players exploring the support role for the first time.

The complete ability set was unveiled through Riot Phroxzon’s social media communications, incorporating several adjustments before the official League of Legends patch 13.5 release.

  • Health growth per level: 84 >>> 69
  • Base mana: 400 >>> 440
  • Strategic Insight: The health reduction increases Yuumi’s vulnerability when detached, emphasizing strategic attachment timing. Meanwhile, the mana increase enables more frequent ability usage during early laning phase, compensating for her increased mana costs on key abilities.

    Feline Friendship Passive Mechanics

    Passive: Feline Friendship

  • When Yuumi’s spells or attacks affect champions, she heals herself and charges a heal for her allies. If she Attaches within the next 4 seconds, she brings the heal to her ally. While Attached, this effect automatically occurs.
  • While Attached, Yuumi builds friendship whenever her ally kills champions and minions. Each ally has their own unique Friendship score. While Attached to her Best Friend, her abilities gain bonus effects.
  • Cooldown: 20-10 seconds (levels 1-11)
  • Heal amount: 25-110 (+15% AP) levels 1-18
  • While her passive is ready, Yuumi’s auto attack range is increased by 50.
  • Advanced Mechanics: The Friendship system rewards consistent partnership with specific allies. Prioritize attaching to hyper-carries or champions with strong scaling potential. The increased auto-attack range when passive is available enables safer poke opportunities during laning phase, but requires careful positioning to avoid unnecessary damage.

    Common Mistake: Many players fail to utilize the 4-second window to deliver charged heals after detaching. Practice quick attach-detach cycles to maximize healing output while maintaining safety.

    Prowling Projectile (Q) Complete Analysis

    Q: Prowling Projectile

  • Yuumi fires a missile that slows the first enemy hit. If cast while Attached, Yuumi can control the missile for a short period before it becomes Empowered, greatly accelerating and slowing enemies by an increased amount.
  • Best Friend bonus: The slow will always be empowered and hitting enemy Champions also grants 10/12/14/16/18/20 (+10% AP) on-hit damage to her ally for 5 seconds. This damage is increased by up to 75% based on her ally’s crit chance.
  • Cooldown: 7.5/7.25/7/6.75/6.5/6.25
  • Base damage: 60/90/120/150/180/210 (+20% AP)
  • Base slow: 20% for 1 second
  • Empowered damage: 80/140/200/260/320/380 (+35% AP)
  • Empowered slow: 55/60/65/70/75/80% decaying over 2 seconds to 20%
  • Missile width: 65 >>> 60
  • Hitting an enemy with this ability now reveals them (will not reveal stealthed enemies)
  • Adaptive force to Yuumi and her ally: Removed
  • Strategic Application: The reduced missile width requires more precise aiming, but the empowered version’s significant slow makes it excellent for setting up kills or disengaging. The crit-scaling bonus damage synergizes exceptionally well with marksman carries building critical strike chance items.

    Pro Tip: Use the reveal effect to check bushes safely from distance. The removal of adaptive force shifts this ability’s value from stat buffing to crowd control and damage amplification.

    E Ability Transformation and New Shield Mechanics

  • Best Friend Bonus: Yuumi gains an additional 10-20% heal and shield power (based on ally level) and her Anchored ally gains 3/5/7/9/11 (+4% AP) on-hit healing. This is affected by Yuumi’s Heal and Shield power.
  • No longer procs Summon Aery’s shield
  • Now shields allies instead of healing
  • Cooldown: 12/11.5/11/10.5/10 seconds
  • Mana cost: 80/90/100/110/120
  • Shield amount: 90/120/150/180/210 (+30% AP)
  • Movespeed bonus: 20% while shield persists
  • Attack speed: 35% (+8% per 100 AP)
  • Restores 20/24/28/32/36 mana to her Anchor (not herself), increased by up to 100% based on their missing mana
  • Gameplay Impact: The shift from healing to shielding prevents grievous wounds from completely countering her sustain. The mana restoration mechanic is particularly valuable for mana-hungry carries, effectively extending their lane presence and trading potential.

    Optimization Strategy: Time your E usage when your ally is low on mana for maximum restoration value. The movement speed and attack speed bonuses create powerful engage/disengage opportunities and enhance your carry’s damage output during fights.

    Common Error: Avoid spamming E without considering mana costs. The escalating mana expense requires careful resource management throughout the game.

    Final Chapter (R) Ultimate Ability Breakdown

  • For 3.5 seconds, Yuumi fires 5 magical waves that affect enemies and allies. If cast while Attached, Yuumi can steer the waves to follow her mouse.
  • For ally champions, the waves heal. The heal is increased by 130% on her Best Friend. All excess healing is converted to a shield, lasting 3 seconds after the ability ends.
  • For all enemies, the waves deal damage and apply a stacking slow
  • Cooldown: 120/110/100
  • Damage per wave: 75/100/125 (+20% AP)
  • Heal amount per wave: 35/50/65 (+15% AP)
  • Slow duration: 1.25 seconds
  • Slow amount: 10% +10% per wave hit (up to 50% slow)
  • Best Friend bonus: Waves also grant Yuumi’s Best Friend 20/40/60 (+10% AP) armor and magic resist for the duration of the spell.
  • Strategic Usage: This ultimate serves as both a powerful teamfight tool and emergency sustain ability. The steerable waves allow precise targeting in chaotic fights. The stacking slow effectively zones enemies or locks down targets, while the Best Friend defensive bonuses provide crucial survivability for your primary carry.

    Advanced Technique: Position waves to hit multiple allies while simultaneously damaging and slowing enemies. The excess healing conversion to shields makes this ability excellent for sustaining through burst damage scenarios.

    Timing Consideration: Use during objective contests where the area denial and team sustain provide maximum value. The long cooldown necessitates strategic conservation for crucial moments.

    Advanced Yuumi Strategy and Common Pitfalls

    Optimal Best Friend Selection: Identify your team’s primary win condition early. Hyper-carries like Jinx, Vayne, or Kog’Maw benefit tremendously from Yuumi’s bonuses. Alternatively, mobile assassins or bruisers can create unexpected synergies with the enhanced mobility and sustain.

    Ability Rotation Mastery: Maximize your effectiveness by sequencing abilities around passive availability. The ideal pattern: proc passive, deliver heal, use Q for poke/slow, then E for shielding and stats. Save ultimate for engage/disengage or teamfight sustain.

    Mistake Avoidance Guide:

    • Don’t remain permanently attached – use detachments to proc passive safely
    • Avoid attaching to doomed allies – sometimes sacrificing your carry preserves your streak
    • Manage vision control – your attached state doesn’t make you invulnerable to well-coordinated engages
    • Adapt your Best Friend choice if your initial selection underperforms

    Itemization Tips: Focus on ability power and heal/shield power items. Staff of Flowing Water synergizes exceptionally with your E’s attack speed and movement speed bonuses. Mikael’s Blessing provides crucial cleanse utility for your Best Friend.

    Laning Phase Strategy: Use Q poke strategically to control lane pressure. Your early game vulnerability requires careful positioning and attachment timing. Coordinate with your lane partner to maximize passive procs and friendship building.
