League of Legends 12.4 Patch Notes Champion Balances


  • Q – The Darkin Blade
    • Sweetspot Damage : 150% -> 160%

We’re still keeping an eye on the changes to the fighter item system, but it’s clear that Aatrox drew the short sword. This buff should hit the sweet spot.


  • E – Tantrum
    • Physical Damage Reduction : 2/4/6/8/10 (+3% bonus armor) (+3% bonus magic resist) -> 5/7/9/11/13 (+3% bonus armor) (+3% bonus magic resist)

 Last patch’s nerfs made our mummy a little too sad. His E passive’s damage reduction is now capped, so we can return some power to the ability by making the baseline stronger.


  • R – Enchanted Crystal Arrow
    • Missile Speed : 1600 -> 1500 (+200 per second of travel time), up to 2100

Ashe has been fairly out of the meta for a while now, so we’re taking the opportunity to give the Frost Archer some more reliable utility with those magical, cross-map ults.


  • Base Stats
    • Base Health Regeneration : 8.5 -> 7.5

We’re lowering the robot’s innate sustain so that he has to be a little more cautious in lane.

Dr. Mundo

  • Base Stats
    • AD Growth : 4.2 -> 3.5
      • Attack Damage : 61-132.4 (levels 1-18) -> 61-120.5 (levels 1-18)
  • R – Maximum Dosage
    • Cooldown : 110/100/90 seconds -> 110 seconds at all ranks

Dr. Mundo’s been tearing up top lane. We’re pulling some of his baseline offensive power so he has to make better use of his medical kit to successfully sedate his patients.


  • Base Stats
    • Attack Speed : 0.571 -> 0.625
  • W – Harsh Lesson
    • Bonus Physical Damage : 3/3.5/4/4.5/5% (+2% per 100 AD) of target’s maximum health -> 3/3.5/4/4.5/5% (+4% per 100 AD) of target’s maximum health
  • Bugfixes
    • Fixed a bug where, if Illaoi died right after pulling an enemy’s Spirit with E – Test of Spirit, nearby Tentacles would not attack the Spirit

Illaoi hasn’t found her footing yet this season, and the fighter item changes haven’t done the priestess any favors either. She can already hit some wildly high highs, so we’re bolstering her baselines to help her release the kraken.


  • Base Stats
    • Armor : 21 -> 24

The Spear of Vengeance hasn’t been very scary recently. We’re buffing her so she can play more aggressively early and survive lane more reliably.


  • Q – Piercing Light
    • Mana Cost : 50/60/70/80/90 -> 48/56/64/72/80

 The Sentinel of Light hasn’t actually seen much light this season, so we’re letting him use his shining spells more aggressively before he gets Essence Reaver.


  • E – Tidecaller’s Blessing
    • On-Hit Damage (Per Hit) : 20/35/50/65/80 (+20% AP) -> 25/40/55/70/85 (+20% AP)

Last patch, we tide a small nerf to Nami’s E when we adjusted her passive so that her power would remain at sea level. It turns out she actually sank a bit as a result, so we’re reeling that part of the change back in.


  • Base Stats
    • Gameplay (Hitbox) Radius : 80 -> 65 
  • Q – Blooming Burst
    • Additional Bloom Damage : 40/60/80/100/120 (+20% AP) -> 40/65/90/115/140 (+20% AP)
  • W – Shapesplitter
    • Cooldown : 20/19/18/17/16 seconds -> 16/15/14/13/12 seconds
  • QoL Changes
    •  NEEKO’S REAL SHO’MA : When playing as Neeko, your center HUD (i.e. the buff icons above your skills) will now always display your actual buffs, rather than the buffs of the ally you are disguised as if using Passive – Inherent Glamour. Enemies who click on you will still see the buffs of the ally you are disguised as in the target UI at the top of their screen.

Our curious chameleon has been sitting at a low winrate for quite some time and could use a little love. We’re trimming down her THICC hitbox to match those of similar characters, as well as refining some of her tricks. An extra boost to her blossoms should help her with waveclear and make her spell combos really pop-blossom off.

Nunu & Willump

  • Base Stats
    • Health Growth : 82 -> 76
    • Health at Level 18 : 1934 -> 1832
  • Q – Consume 
    • Healing From Champions : 60/88/116/144/172 (+72% AP) (+8% bonus health) -> 45/71/87/108/129 (+54% AP) (+6% bonus health)

Nunu has been playfully toeing the line into OP territory across all brackets for a while now, but this last patch finally broke the ice. We’re bringing him and <strike>William</strike> Willump back into a more reasonable state by tapping down on their general tankiness rather than detracting from their jungle clear and signature snowy skills.


  • Passive – Royal Privilege
    • Additional Physical Damage : 15-83 (levels 1-18) (+55% bonus AD) (+30% AP) -> 15-83 (levels 1-18) (+45% bonus AD) (+30% AP)

The empress continues to be a little too oppressive in higher levels of play, so we’re reducing the AD scaling on her passive to curb her waveclear and snowball potential. 


  • Base Stats
    • Base Armor : 31 -> 36

Rumble is weak, especially in the top lane. We’re fortifying him to be more in line with other melee laners so he can get scrappier with his enemies.


  • Base Stats
    • Health Growth : 93 -> 100
    • Health at Level 18 : 2181 -> 2300

The Rift’s 1 mama’s boy has dropped in effectiveness and winrate a bit more than other fighters last patch, so we’re giving him a small buff. 


  • Base Stats
    • Base Armor : 23 -> 21
    • Armor Growth : 3.75 -> 4.0
    • Armor at Level 18 : 86.75 -> 89
  • E – Event Horizon
    • Cooldown : 18/16.5/15/13.5/12 seconds -> 20/18/16/14/12 seconds
  • Bugfixes
    • Fixed Q – Baleful Strike‘s tooltip to correctly state that last hitting enemy champions grants 1 stack of Phenomenal Evil, not 3

Veigar is standing head-and-shoulders above the competition. His shadow is especially tall in bot lane, so we’re adjusting his scaling in a way that’ll impact him more in bot lane than in mid.


  • E – Bladecaller
    • Critical Strike Chance Damage Multiplier : Deals 0.5% -> 0.75% more damage per 1% critical strike chance

While we’re happy that Xayah has lethality options, they’ve been overshadowing her crit builds. The Rebel’s gameplay is healthier and better suited to her identity when she builds at least some attack speed, so we’re increasing the crit scaling on E – Bladecaller to bring back her fast and furious feathers.


  • Uncharged Basic Attack
    • Magic Damage : 15-40 (levels 1-18) (+4% AP) -> 10-25 (levels 1-18) (+3% AP)
    • Damage Increase : 300% -> 500% against enemies below 35% health
  • Charged Basic Attack
    • Slow : 20/25/30/35/40% -> 14/23/32/41/50% (based on Q rank)
    • Slow Duration : 1.5 seconds -> 1 second
  • Q – Burst Fire
    • Damage : 10/15/20/25/30 (+110% AD) -> 9/13/17/21/25 (+110% AD)
    • [UPD] BURSTIER BURSTS : Burst Fire’s critical strikes now also multiply its base damage (in addition to its AD ratio)
    • Excess Attack Speed to AD Conversion : 50% -> 60%
  • W – Ultrashock Laser
    • Slow : 50/55/60/65/70% -> 30/40/50/60/70%
    • Cooldown : 10 seconds at all ranks -> 13/12/11/10/9 seconds
  • E – Spark Surge
    • Cooldown : 23/21.5/20/19.5/17 seconds -> 23/22/21/20/19 seconds
    • Cooldown Reduction : 1.5 seconds -> 1 second per champion hit with charged basic attacks or abilities
  • R – Lightning Crash
    • Bonus Attack Speed : 30/35/40% -> 30% at all ranks
  • Bugfixes
    •  Q – Burst Fire crits will no longer trigger Navori Quickblades’ passive to reduce the cooldown of Q – Burst Fire
    • Tear of the Goddess now correctly treats Q – Burst Fire as a basic attack and will no longer grant stacks when it is cast; Zeri’s right-click basic attack will continue to be treated as a spell and trigger Tear stacks

Uncharged basic attack base damage and AP ratio decreased; damage amp against low-health enemies increased. Charged basic attack slow rate and duration decreased. Q base damage decreased but now also multiplied in crits; excess AS to AD ratio increased. W slow decreased early; cooldown increased early but now decreases with rank. E cooldown decreased. R bonus attack speed no longer increases with rank.

Zeri’s spark still has a bit more shock than she needs, so we’re nerfing her overall power in a way that should hit her bruiser builds harder than her crit builds.

League of Legends 12.4 Patch Notes Items

[NEW] Ally Item Pings Now Available!

You can now display your allies’ item cooldowns and charges in-game by pinging an item’s icon in the “Tab” scoreboard! Item icons in the scoreboard will also have timer VFX to visually indicate their status, similar to those on Summoner Spells. 

Rejuvenation Bead
  • Total Cost : 150 gold -> 300 gold
  • Base Health Regeneration : +50% -> +100%
  • Sell-Back Ratio : 70% (sells for 105 gold) -> 40% (sells for 120 gold)

Buying three Rejuvenation Beads has recently cropped up as a powerful item start strategy. However, it offers weak early game champions a bit too much sustain without asking for enough tradeoffs mid-game. We’re adjusting it to require some more commitment and will look at changing Doran’s items if players struggle to survive, especially in tough solo lanes.

Crystalline Bracer
  • Total Cost : 650 gold -> 800 gold
  • Base Health Regeneration : +50% -> +100%
Knight’s Vow
  • Combine Cost : 700 gold -> 400 gold (total cost unchanged)
  • Base Health Regeneration : +150% -> +200%
Warmog’s Armor
  • Combine Cost : 650 gold -> 500 gold (total cost unchanged)

League of Legends 12.4 Patch Notes Systems

Support Gold Income 

As for the context: We value flexible picks and creativity when they don’t substantially corrupt gamestate or abuse systems that have very specific values and aren’t meant to support other strategies. Using support income items in a solo lane to avoid having to care about income and opting out of traditional league is not the intended use case for those items and leads to degenerate gameplay. This is something we’re aiming to find a strong solve for in the future, but for now we’re adjusting some systems to make sure this strategy doesn’t waterfall into doing weird things to other systems. Objective and CS bounties weren’t made to account for this kind of strategy so we’re updating them to properly adjust for atypical income strategies. We’re also hitting early farming for the income item solo laners so that they don’t circumvent the cs penalty by leaving lane soon after it hits.

Key Points:

  • We value flexible picks and creativity
  • Support items top led to over-roaming, absent laning phases, and overall degenerate gameplay.
  • We’re working on a longer term solution, but these changes should help reduce more immediate, potential issues
  • Updating Objective and CS bounties to adjust for atypical income strats

 While we value flexible picks and creativity, sometimes 

Spellthief’s Edge, Relic Shield, Steel Shoulderguards, & Spectral Sickle

Tribute/Spoils of War (Passive) – Minion Farming Penalty : Receive diminishing gold from excessive ||| (4 minions per minute) -> (2 minions per minute until 5 minutes; 4 minions per minute thereafter) minion kills. This diminished gold penalty is now also more severe during the first 5 minutes of the game. (All else unchanged)

  • GOLD VALUE BOUNTIES : Gold value bounties (a.k.a. CS bounties) are now based on the number of support gold income items on each team, rather than assuming each team has one support gold income item
  • OBJECTIVE BOUNTIES : Enemy gold leads are now significantly less likely to lead to Objective Bounties activating if there are two or more support gold income items on your team
Objective Bounties

Unrelated to the gold income items above, we’re also shortening the deactivation timers for Objective Bounties to address some extreme swing cases. When an Objective Bounty period ends, the losing team should still be behind, but the lingering duration allowed some cases where a losing team could catapult ahead after claiming multiple bounties in a row.

  • BOUNTY LINGER PERIOD : 15 seconds -> 5 seconds after Objective Bounties fall off
