Complete guide to LoL Patch 13.15: Champion balance changes, timing details, and strategic insights
Patch 13.15 Overview
League of Legends enthusiasts eagerly anticipate the arrival of patch 13.15, scheduled for deployment on August 2nd, 2023. This update introduces crucial balance adjustments targeting several high-priority champions that have dominated recent competitive play.
The upcoming League of Legends patch 13.15 focuses on recalibrating champion power levels, particularly addressing Kai’Sa’s overwhelming AP build and Ivern’s persistent jungle dominance while providing much-needed assistance to struggling fighters like Yasuo and Yone.
Riot Games continues their systematic approach to game balance with this incremental patch, deliberately avoiding sweeping system changes in favor of precise champion adjustments. The development team aims to stabilize the meta without introducing disruptive shifts that could undermine recent item reworks.
While patch 13.15 doesn’t contain massive systemic overhauls comparable to the recent ADC item rework, it strategically targets problematic champions that have skewed win rates and pick rates across various competitive tiers. These adjustments aim to create healthier gameplay patterns while maintaining champion identity.
League of Legends Patch 13.15 deployment follows Riot’s standard release schedule, beginning with Oceanic servers before progressively rolling out to other regions throughout the day. Players should prepare for approximately three hours of matchmaking downtime preceding the update.
Server maintenance typically commences during early morning hours for each region, with exact timing varying by location. Competitive players should coordinate practice schedules around these maintenance windows to avoid disrupted training sessions.
Strategic preparation for patch transitions involves reviewing detailed change logs beforehand and adjusting champion pools accordingly. Proactive adaptation to balance shifts often provides competitive advantages during the initial post-patch period.
Champion Balance Changes Deep Dive
Kai’Sa’s dominant AP build faces significant nerfs targeting her scaling potential and survivability. The adjustments specifically address her hybrid damage profile that has proven difficult to itemize against in professional matches.
Ivern mains express mixed reactions to the latest changes, as the champion receives both nerfs and adjustments to his companion mechanics. While Daisy’s durability decreases, Smite modifications partially compensate by reducing its effectiveness against summoned units.
Yasuo and Yone receive comprehensive buffs addressing their itemization struggles following the ADC mythic rework. The changes focus on mid-game power spikes and survivability, particularly enhancing their defensive capabilities during critical engagement windows.
Multiple pet-reliant champions undergo systematic adjustments to summoned unit durability and functionality. Annie, Heimerdinger, and Yorick all experience changes to their companion mechanics, creating new strategic considerations for both the summoners and their opponents.
Nerfed Champions
Kai’Sa Adjustments:
- AD ratio reduced: 60 – 100% >>> 60 – 90%
- Armor and MR AP scaling removed
- Health: 1300/2200/3100 (+75% AP) >>> 1150-3500 scaling non-linearly with level (+50% AP)
Naafiri Modifications:
- First hit base damage reduced: 20/25/30/35/40 >>> 10/15/20/25/30
- Second hit base damage reduced: 30/70/110/150/190 >>> 20/60/100/140/180
- AD growth reduced: 3.4 >>> 3
- Health growth reduced: 109 >>> 104
Ivern Updates:
- Daisy duration reduced: 60 seconds >>> 45 seconds
- Daisy base health changed: 1300/2600/3900 >>> 1000 – 4000 (based on level)
- Daisy base resistances changed: 20/ 60/ 100 >>> 30 – 90 (based on level)
- Daisy resistances no longer scales with 5%
- Daisy AD AP ratio reduced: 30% >>> 15%
Buffed Champions
Yasuo Enhancements:
- Critical strike chance damage ratio increased: 1.2 >>> 1.3
- Critical strike chance damage ratio increased: 2.5% damage per 10% crit >>> 3.5% damage per 10% crit
- AD growth increased: 3.5 >>> 3.8
- Base shield now uses non-linear level scaling (+30 at level 3, +75 at level 6, +125 at level 9, +79 at level 16) The idea here is to give Yasuo a stronger shield in the mid game to counteract Shieldbow’s semi-recent move away from being a Mythic item.
- Base shield increased: 45 – 65 (based on level) >>> 55 – 75 (based on level)
Yone Improvements:
- Critical strike chance damage ratio increased: 2.5% damage per 10% crit >>> 3.5% damage per 10% crit
- Base shield increased: 45 – 65 (based on level) >>> 55 – 75 (based on level)
Nami Buffs:
- Base movement speed increased: 90 >>> 100
- AP Ratio increased: 20% >>> 25%
- Base damage increased: 75/130/185/240/295 >>> 90/145/200/255/310
Quality of Life Updates
Note: Rell’s changes are mostly quality of life, but some of them are slight buffs/nerfs to the champion.
Rell Adjustments:
- All spells and auto attacks now apply the damage first, then apply the passive.
- Q now maintains its absolute direction after flashing rather than its original target
- Increased dash speed before the flip once she’s locked onto a target. This should both solve some bugs and make the ability feel quicker and more responsive.
- Fixed a bug that was causing Rell’s W – Mount Up to not apply bonus damage to Epic monsters.
Understanding these changes requires analyzing champion performance across different skill brackets. Professional play often showcases different meta trends compared to solo queue, making some adjustments more impactful at specific competitive levels.
Strategic Implications and Meta Shifts
The pet champion adjustments create new dynamics for jungle and lane matchups. With summoned units receiving durability changes and Smite effectiveness modified against pets, strategic priorities shift for both summoners and their opponents.
Yasuo and Yone players must reconsider their itemization paths and power spike timings. The enhanced critical strike ratios and defensive improvements enable more aggressive mid-game play patterns, potentially revitalizing their presence in competitive matches.
Kai’Sa mains face significant adaptation challenges as her hybrid build path undergoes substantial nerfs. Players may need to prioritize traditional ADC itemization or explore new hybrid combinations that maximize her remaining strengths while mitigating the scaling reductions.
Common Strategic Mistakes to Avoid
Many players underestimate the impact of pet durability changes on objective control. The adjusted Smite damage against summoned units means timing and target selection during dragon and Baron fights require renewed attention and practice.
Another frequent error involves overestimating Yasuo and Yone’s early game strength. While their mid-game receives significant buffs, their laning phase remains relatively unchanged, requiring careful resource management until reaching critical item thresholds.
Advanced Optimization Strategies
High-level players can leverage the precise timing of Yasuo and Yone’s non-linear shield scaling. Understanding exactly when these defensive bonuses activate enables calculated aggressive plays that capitalize on temporary power advantages.
Jungle pathing adjustments become crucial for Ivern players facing reduced Daisy duration. Optimizing companion usage around objective spawn timers and gank opportunities maximizes efficiency despite the shorter summon duration.
The meta shift likely favors champions that can capitalize on the adjusted power dynamics. Counter-picks against the buffed champions may gain prominence, while traditional answers to the nerfed champions might require reassessment.
