Patch 4.16 Notes

Posted on at 12:26 PM by Moobeat

Patch 4.16 is on the way and the official patch notes have been posted!
Continue reading for the full set of patch notes, including Cassiopeia's rework, loads of bug fixes, a visual update for in-game announcements, and much more!

Here's the full patch notes, this time with an introduction by Scarizard:
"Hey y'all, 
Welcome to patch 4.16! We've got a sizeable Gameplay Update to everyone's favorite snake lady Cassiopeia, but aside from that we're going pretty light on the balance side. Similar to 4.15, a lot of the changes you'll see below are focused on smoothing out some champion interactions, or just plain ol' bugfixin' goodness (Check out the context below for what's happening with Wall-Slams!) 
For all things non-balance though, we've got a little more meat for you. First up, in addition to her Gameplay Update we mentioned earlier, Cassiopeia is joined by Renekton for updates to their visuals! Follow that up with new base splash arts for the desert-dwelling duo and Akali and Orianna, and this patch is set to delight all the art fans out there. 
As we mentioned last patch, we've started patching some finished pieces of Summoner's Rift to the live environment in order to minimize the size (and download times) of the eventual Summoner's Rift launch patch. These pieces aren't usable and we don't have an official release date - for now these pieces will just be preemptively sitting on your hard drives. 
That's it for me! Check out the full breakdown in the notes below, and be careful out on the Rift - there's been a lot of sandstorms recently...

ANNOUNCEMENT VISUAL UPDATEIn-game announcements (killing sprees, map objectives, etc.) have received a visual update!
SHIELD CLARITYMinion and turret health bars now display shield strength



Azir, the Emperor of the Sands, will be released a bit later during Patch 4.16.


Cassi's received a gameplay update! Focusing on her new passive Aspect of the Serpent, she's now more about stacking up poisons for massive end-game scaling than being a dominant laning force. Mana costs, cooldowns, base damage and ratios have all been mixed up to compensate - read below for the numbers!
Cassiopeia's high DPS has always sat alongside her poison as defining characteristics of the serpent lady. Historically however, these traits have led to oppressive gameplay that's as challenging for the opponent to deal with as it is to understand (THANKS DAMAGE OVER TIME). To preserve both sides of what makes Cassi unique, we realized we had to modify the relationship between the two.

In this update, the key to Cassiopeia's heavy-hitting damage potential lies within her new passive, Aspect of the Serpent. Cassi builds power throughout the game as she poisons enemy champions, unlocking stat bonuses to fuel her (now more powerful) Twin Fang. This new aspect (heh) of growing her end-game scaling allows us to solidly push her into the 'completely-absurd-damage-potential' space she's currently hanging around. This comes at the cost of some early game power, but make no mistake - you can expect to see a late-game Cassiopeia as one of the most potent damage threats in the League.

TEXTURE UPDATETextures for Renekton's base, Galactic, Outback and Bloodfury skins have been updated
SPLASHRenekton's base splash art has been updated
BIORenekton's in-client bio has been updated


R - Pyroclasm

CLARITYNow has a secondary targeting indicator that shows bounce radius.


W - Valkyrie

BUGFIXFixed a bug where Valkyrie being interrupted would halt Corki's movement but still extend Valkyrie's damage field.


Gnar's ultimate and similar skills work with player-made terrain (this time, Jarvan'sactually helping). Part one of three.
Continuing to clean up GNAR! with some consistency work across all wall-slams. As with the changes to Poppy and Vayne you'll see below, we'll be watching to see the effects of these changes play out and ready to adjust accordingly.


NEWCOME ON AND SLAMNow detects collision with player created terrain (Anivia's Crystallize, Azir's Emperor's Divide, Jarvan's Cataclysm and Trundle's Pillar of Ice)
WAP!Fixed a bug where using GNAR! on a dashing unit would cancel their movement, but not stun them, if they hit a wall.


Q - Bladesurge

SORRY WICKDFixed a bug where stopping Bladesurge mid-dash would still deal damage to her target.


Tried to make a joke, but Poppy doesn't know any. Part two of three.

E - Heroic Charge

NEWAND WELCOME TO THE SLAMNow detects collision with player created terrain (Anivia's Crystallize, Azir's Emperor's Divide, Jarvan's Cataclysm and Trundle's Pillar of Ice)


Full disclosure - we're not 100% on what the impact of changing this will be as it's hard to know how much random Energy this was giving Shen in teamfights. If Shen needs love as a result we're happy to give it, but he shouldn't have to rely on a bug for power.

E - Shadow Dash

REMOVEDNO DISRESPECTFixed a bug where taunting dead champions would give Shen bonus energy.


In 4.13 we introduced a line indicator (similar to Xerath) over his previous circular one, hoping it would increase accuracy and satisfaction for Varus players - as it turns out, neither of those things happened (OOPS) so we're taking it back to the original. Thanks for the feedback, y'all!

Q - Piercing Arrow

WHOOPSLine indicator removed (Now uses range circle again as per previous functionality)


As if Vayne players needed any more highlight reel material. Part three of three.

E - Condemn

IT'S TIME TO SLAM JAMNow detects collision with player created terrain (Anivia's Crystallize, Azir's Emperor's Divide, Jarvan's Cataclysm and Trundle's Pillar of Ice)


Tides of Blood is now doing what everyone thought it was doing already.
The decision to fix this wasn't for power reasons, but rather to fulfill player expectations on how Tides of Blood should work. We'll be monitoring to make sure he doesn't go crazy, but for now Vlad players are a little less thirsty.

E - Tides of Blood

TECHNICALLY A BUFF TO GUNBLADENow correctly increases healing from Vladimir's Spell Vamp (and Lifesteal)


With the Chronokeeper back in the spotlight, we figured it's as good a time as any to help players realize when he's got their back.

R - Chronoshift

YOU ASKED FOR ITNow subtly tints the target's screen
