System Changes

Dragon Eggs

Developer's notes
The streets of Neon Nights have been visited by the benevolent Treasure Dragon—just long enough for the dragon to drop a few Eggs and split. Legend has it that this dragon left the world of Dragonlands in search of distant lands in need of equally distributed treasure—could our world be next (please)?
At the start of the game, every player gets an egg.
There are 5 different sized eggs. The larger the egg, the more stuff inside but the longer it takes to hatch.
Every player gets the same size egg.
Every egg has the same value of contents (though items are different)
Every egg will contain a Tome of Traits, but bigger eggs will have Components, completed Items, Radiant Item(s), and more!

Augment Combinations

Developer's notes
We’ve changed the odds of various Augment combinations to keep things fresh and fun towards the end of the set.
Reintroduced Gold/Silver/Silver
Lowered the odds of a Prismatic for the 3rd augment
Increased the odds of an all Prismatic game
Total odds of any Prismatic in game is unchanged

Large Changes

Metabolic Accelerator Now only available on 1-4

We’re giving a few units this patch a bit more damage at the expense of some crowd control.
Time flies like Robinsongz into Rank 1.

Making sure every 3-cost unit gets a shot as the carry, because sharing the carrying is truly caring.
All aboard the gain train with your personal trainer, Cho’Gath, whose diet of champions is the diet for champions!

Developer's notes
Orianna has gone the entire set just being that supportive unit you throw in to hit some complementary traits. With these buffs, we’re giving her the ball to score her own goals instead of just racking up assists, or input sportball reference—idk me gamer.
That Draven Attack Damage buff got me repeating this line out loud.
Ahri Attack Speed: 0.75 ⇒ 0.8
Alistar Mana buff: 85/170 ⇒ 80/160

Developer's notes
It’s time to let the monster out…for two more patches.
Silco Attack Speed: 0.65 ⇒ 0.7
Silco Unstable Concoction Explosion Damage: 250/500/5000 ⇒ 350/600/5000

Items

Developer's notes
Damage over time spells (DOTS) have been able to turn Morellonomicon into a massive damage item and not just a counter to healing. We’re shipping a pretty big nerf to the burn book in hopes players will find other ways to itemize some of the mean girls (Renata Glasc, Ahri, etc.) using it. This is a change that we had originally planned for Dragonlands, but have gone early with it to see just how it will impact our DOT users.
Morellonomicon Max Health Burn: 20% ⇒ 10%

Small Changes

Augments

Developer's notes
Small, like the error I made putting our Jayce and Viktor changes in this section—oops!
Cybernetic Implants Health: 150/250/350 ⇒ 125/200/300
Cybernetic Shell Health: 150/250/350 ⇒ 125/200/300
Cybernetic Uplink Health: 150/250/350 ⇒ 125/200/300
Golden Gifts I/II number of Gray Orbs: 2/3 ⇒ 3/4
Thieving Rascals low roll (worst case scenario) improved

Traits

Developer's notes
With the new Dragon Eggs, accessing some of these harder to reach chase traits is a bit easier, so we’re preemptively nerfing their power in response.
Clockwork base Attack Speed: 10/35/80% ⇒ 10/35/70%
Scholar Mana regen: 5/12/25 ⇒ 5/15/25
Innovator Hextech Dragon base Health: 1125 ⇒ 1025

Units: Tier 1

Developer's notes
Let’s get flipping.
Singed Health: 650 ⇒ 700

Units: Tier 2

Developer's notes
Warwick is very dependent on his traits for power. With the injection of an extra Tome of Traits we’ve unintentionally buffed Zaun’s cutest pup, which is why we’re shipping a preemptive nerf to keep him on the leash during the final nights of Neon Nights.
Rek’Sai max Mana buff: 60/80 ⇒ 50/70
Warwick Eternal Hunger Healing: 35/45/65 ⇒ 30/40/50

Units: Tier 3

Ekko Parallel Convergeance Damage: 150/200/350 ⇒ 150/200/400

Sivir Richochet bonus Attack Speed: 45/65/250% ⇒ 30/60/300%

Units: Tier 5

Developer's notes
After this nerf, Viktor may need to let Jayce borrow his cane—I mean that is why they call it Ourcane.
As a reminder, Zeri fires 5 bullets per auto, so the damage is actually going up by 10 per auto, which is still small, but should feel a bit better.
Jayce Health: 1000 ⇒ 999
Kaisa Mana nerf: 75/150 ⇒ 80/160
Viktor Health: 850 ⇒ 851
Veigar Furyhorn Storm Damage: 250/300/777 ⇒ 300/325/777
Zeri Lightning Crash passive on Hit magic damage: 10/20/40 ⇒ 12/20/40

Double Up

Systems

Developer's notes
Previously players could purchase units while reinforcing, but could not manipulate their own bench. This resulted in cases where a player would want to buy champions but could not due to their bench being full and having no way to sell units to make room as you can in standard mode. While not a common occurrence, it was still a pain point we wanted to resolve.
You can now return to your own board to interact with your bench after reinforcing your partner.
As a result the unit shop UI is also turned off while you are watching your partner’s board, but it will reappear when you are looking at your own board.

Bug Fixes

Ashe Volley Tooltip now correctly states 20% Attack Speed slow
