Five biggest changes in League of Legends Patch 9.12
Posted by Ram Ronquillo on June 14, 2019

A new League of Legends patch is upon us! Patch 9.12 introduces quite a lot of changes. It brings big changes to fewer champions compared to Patch 9.11.

Three new champion skins are included in the patch and these are Dark Cosmic Jhin, Dark Star Karma, and Dark Star Shaco. They join the roster of the already established Dark Star skins.

Before we get to the five biggest changes, the patch introduces the monumental rework of Mordekaiser. This is a total overhaul to his kit, including the removal of his former ultimate, Dragon Force or Children of the Grave (depending on which of the two you remember). Instead, the ultimate of the Iron Revenant now banishes a target to the Death Realm where he and the banished enemy will be isolated from the rest of the Rift. In the process, he steals 10% of their core stats for the duration. If he is able to kill the banished enemy while in the Death Realm, he keeps the stats until the enemy respawns.

That said, we won’t go through his kit and the changes made.

With that out of the way, let’s get to to the five biggest changes that League of Legends Patch 9.12 brings.

Passive – Petricite Burst

  • NEW Now stores up to 2 charges which will be consumed on subsequent basic attacks
  • BASE DAMAGE 5-47.5 (levels 1-18) ⇒ 9-60 (levels 1-18)
  • NEW Deals 70% less damage to minions

Q – Chain Lash

  • DETONATION DAMAGE 45/70/95/120/145 (+0.60 ability power) ⇒40/60/80/100/120 (+0.40 ability power)
  • DETONATION AOE 200 range on minions ⇒ 180 range on minions

W – Kingslayer

  • HEAL 60/80/100/120/140 (+0.4 ability power) ⇒ 70/90/110/130/150 (+0.50 ability power)

E – Abscond/Abduct

  • REMOVED No longer shields himself for 2 seconds on the first cast
  • COOLDOWN 18/16/14/12/10 seconds ⇒ 18/17/16/15/14 seconds
  • NEW ABDUCT SHIELD Grants a 80/115/150/185/220 (+1.0 ability power) shield on enemy champion or monster hit for 2 seconds


Sylas has maintained his status as a strong champion, especially in professional play. Thus, seeing adjustments to his kit doesn’t come as a surprise. Riot has hit his wave clear through Chain lash by drastically lowering the detonation damage along with its area of effect range on minions. And while they put his passive, Petricite Burst on a charge system while also increasing the damage, they’ve also lowered the damage to minions.

To add to this, Abscond/Abduct now doesn’t give him a shield on the first cast (or Abscond). He gains a shield, instead, on enemy champion or monster hit with Abduct. Which seems like a fair enough trade especially with a higher base shield amount and 100% Ability Power (AP) scaling. However, overall his cooldown across all levels is also drastically higher. These changes seem to reward more aggressive players especially with the higher heal on Kingslayer which includes base heal and AP ratio. This, of course, may take him out of professional play because it lowers his survivability as a champion.



Base Stats

  • HEALTH 432.36 ⇒ 480

Passive – Bop N’ Block

  • MANA REFUND 40-160 (level 1-18) ⇒ 30-160 (level 1-18)
  • SHIELD 80-360 (+0.40 ability power) ⇒ 80-300 (+0.30 ability power)

Q – Prowling Projectile

  • BUGFIX Fixed a bug where the missile would not spawn towards the cursor as intended

W – You and Me!

  • NEW Enemies now gain an assist on Yuumi when damaging the ally Yuumi is attached to
  • UPDATED SHARED ADAPTIVE FORCE 5/9/13/17/21% of her attached ally’s adaptive force ⇒ 5/7/9/11/13 flat adaptive force (+4/7/10/13/16% of her attached ally’s adaptive force)
  • UPDATED Yuumi’s dash can be interrupted by knock-ups and knockbacks⇒ Yuumi’s dash can be interrupted by any immobilizing CC
  • BUGFIX Fixed a bug where Yuumi would detach unintentionally when trying to attach to another champion outside of her range

Quality of Life Changes

  • Range rings for Yuumi’s Q, W, and R no longer show on Spectator Mode
  • Yuumi now gains the same stealth screen overlay and fade on her model when attached to a champion in stealth
  • The ally that Yuumi’s attached to now has a ring around them that only Yuumi can see


Yuumi is an interesting champion since her launch. At launch, she was very underpowered thus forcing Riot to buff in a hotfix in the same patch she was released. These buffs did their role and made her a drastically better champion. Well… Probably a bit too well.

Her Passive, Bop N’ Block now gives her less mana refund at early levels along with a weaker shield later in the game. The shield changes are a bit more drastic with a difference of 60 at level 18 as well as lowered AP ratio by 0.1.

While changes to You and Me! a bit more interesting. First, the dash mechanic has been updated to be canceled by any form of immobilizing crowd control from just knock-ups and knockbacks. But at the same time, they slightly increased the shared adaptive force between Yuumi and the teammate she is attached to.

Along with the increased base health, the bugfix to Prowling Projectile will make landing the attached version of her ability much easier to land and more reliable. Which is always a good thing.



Q – Inner Flame

  • SLOW 25% ⇒ 35%

E – Inspire

  • COST 60/65/70/75/80 mana ⇒ 50/55/60/65/70 mana
  • MOVEMENT SPEED DURATION 1.5 seconds ⇒ 2.5 seconds (now matches shield duration)

One of the ‘smaller changes’ buffs Karma. While she has seen some time in recent times in professional play, Riot gave her some love, mostly to her utility.

A 10% Inner Flame slow is quite good especially when trying to either chase or run away from champions. To add to this, the lowered mana cost and higher movement speed to Inspire just further helps her in both chasing and disengaging.

It wouldn’t be much of a surprise if she has an increase in play in both solo queue and in professional play with these buffs.



E – Help, Pix!

  • SHIELD 70/105/140/175/210 ⇒ 80/115/150/185/220
  • COST 60/70/80/90/100 mana ⇒ 60/65/70/75/80 mana
  • VFX Cleaned up shield (on allies) and improved Pix’s teleport and hit effects (on enemies)

Passive – Pix, Faerie Companion

  • VFX Cleaned up Pix’s bolts

Q – Glitterlance

  • VFX New purple-ier missiles and hit effects

W – Whimsy

  • VFX Cleaned up buff effect (for allies) and missiles/hit effects (on enemies)

R – Wild Growth

  • VFX Fairy dust, an entirely new and pretty AoE, and cleaned up enemy hit and slow effects

Overall, the changes to Lulu are effect changes except for Help, Pix! Being the first skill that most players max first, the lowered mana cost at higher skill level is just massive with a 20 less cost at max level. Along with this, the shield that Help, Pix! gives is slightly bigger. An increase of 10 across all levels doesn’t seem too big but it is a buff nevertheless especially with its duration lowered in Patch 8.12.

Lulu offers quite a lot to a team especially in terms of survivability and utility and this may increase her play in solo queue and professional play.



Base Stats

  • MANA 400 ⇒ 300
  • MANA REGEN 6 ⇒ 8

Q – Overload

  • RANKS 6 ⇒ 5

  • REMOVED SHIELD No longer grants a shield after consuming 2 Runes
  • UPDATED SPELL DAMAGE BONUS 40/50/60/70/80% (based on Spell Flux’s rank) ⇒ 10/40/70/100% (based on Realm Warp’s rank)
  • BONUS MOVEMENT SPEED 25/28/31/34/37/40% ⇒ 20/25/30/35/40%

  • RATIO 1% bonus mana ⇒ 4% bonus mana
  • COST 50/60/70/80/90 mana ⇒ 40/55/70/85/100 mana
  • BASE CROWD CONTROL Rooted for 0.75 seconds ⇒ Slowed by 35% for 1.5 seconds
  • SPELL FLUX BONUS Increased root duration ⇒ Converts Slow to Root

E – Spell Flux

  • DAMAGE 70/90/110/130/150 ⇒ 60/80/100/120/140
  • COST 60/70/80/90/100 mana ⇒ 40/55/70/85/100 mana
  • NEW Now always bounces off the primary target
  • REMOVED Bounces no longer damage enemies
  • REMOVED No longer spreads Flux to nearby enemies on unit kill

R – Realm Warp

  • RANKS 2 ⇒ 3
  • NEW WARP DAMAGE Overload damage bonus against targets with Flux increased to 40/70/100%
  • NEW Immediately casts at max range when attempting to cast beyond that
  • MINIMUM CAST RANGE 730 ⇒ 1000
  • MAXIMUM CAST RANGE 1750/3000 ⇒ 3000
  • COOLDOWN 180 seconds ⇒ 210/180/150 seconds

Last, but definitely not the least, is Ryze who next to Mordekaiser has the biggest change this patch. How big exactly? Well, this is an overhaul to his current kit and as Riot puts it, is version 7… or 8.

First is his first ability, Overload. The biggest change is the removal of the rune system which allows Ryze to get a shield when casting right. The ability is also maxed out at 5 instead of 6. The base damage took a blow as well, with 5 less damage from the previous level 2 until max.

Next is Rune Prison, which gets a pretty big change since Ryze came out. Instead of being an upfront root, Rune Prison now requires a target to have Spell Flux on him in order to be rooted. Without Spell Flux, it’s just a slow for 35% for 1.5 seconds. It now also scales higher with bonus mana but also costs more to cast in latter ranks.

The changes to Spell Flux affects his overall waveclear. While it now always bounces off the primary target, it also doesn’t deal damage on bounce and of course, spread on unit kill. The damage has also been lowered by 10 across all ranks but the cost is lowered at earlier ranks.

Last is his ultimate, Realm Warp. It now can be leveled up to a max of three from two. It also increases the damage of Overload with enemies with Spell Flux up to a max of 100%. Because of more ranks, it makes sense that they’ve increased the cooldown from a base 180 seconds to a max of 150 seconds, which of course makes late game Ryze even more interesting. While the increased minimum and maximum will take getting used to, especially the increase in the minimum range. However, the automatic adjustment to cast at max range when casting beyond max will be pretty helpful especially for newer Ryze players.

Overall, the new rework is a definite nerf. The removal of the shield and the bounce damage of Spell Flux are pretty big changes to his kit. This may put him lower in the ladders of solo queue and more importantly, professional play.
