Arbiter Input:
17.4 is focused on enabling as many comps as possible through buffing underperforming champions and Traits, but also making some of our more niche lines more usable in a wider variety of games. To do this we’re reworking the Input/Output offering distribution you see with Arbiter and reworking Psionic items to be more general so you aren’t locked out of either Trait based upon their output options or items.
Arbiter Output:
Rodger "Riot Prism" Caudill
Katie "Riot Ukime" Guo
Mid-Patch Updates
JUNE 1STCHAMPIONS
We’re following up 17.4 with a patch that aims to broaden strategies by nerfing the most dominant ones (Vex/Blitzcrank fast 9, Xayah, and Arbiter Leona/Zoe) and shipping buffs to a few units that have fallen out of the meta.
- Ezreal Base AD: 40 ⇒ 45
- Talon Ability Damage: 430/645/1000 AD ⇒ 400/600/1000 AD
- Zoe Ability Damage: 73/110/180% AP ⇒ 68/102/180 AP
- Aurelion Sol Mech Ability Damage: 82/123 AP ⇒ 86/130 AP
- Morgana Mana: 30/90 ⇒ 30/80
- Xayah Base AD: 52 ⇒ 49
- Blitzcrank max Mana nerf: 20/100 ⇒ 30/120
- Vex Ability Damage: 30/45 AP ⇒ 27/40 AP
TRAITS
With our Arbiter rework this patch, Leona generation jumped in its consistency due to the ability to create multiple copies a round, especially at (3) Arbiter, where our nerfs are primarily focused on.
Space Groove as a vertical has been struggling for a couple patches despite a number of buffs to the units, and with a necessary nerf to their capstone units, we’re able to swing bigger with a buff to the power of the trait itself.
- Arbiter, Gain Leona, Every 3 Attacks: 10/18% ⇒ 8/12%
- Arbiter, Gain Leona, Spend 50 Mana: 12/20% ⇒ 10/15%
- Arbiter, Gain Leona, Every 4 Seconds: 15/22% ⇒ 14/18%
- Arbiter, Gain Leona, Each Interest: 20/30% ⇒ 20/25%
- Space Groove (3) Groove Duration: 3s ⇒ 4s
- Space Groove Heal Per Groovian: 8.5% max HP ⇒ 9.5% max HP
- Space Groove AS Per Groovian: 11% ⇒ 12%
- Stargazer Huntress Base AS: 12% ⇒ 15%
- Stargazer Medallion Base Damage Amp: 12% ⇒ 15%
AUGMENTS
Misfits is a far less risky Augment to choose on 4-2, where you’ll know if you’re able to get to level 9 and swap to a mostly Legendary, trait-heavy, board.
- Misfits no longer offered on 4-2
MAY 29THBUG FIXES
We’ve got four bug fixes as we head into the weekend. Our Arbiter fixes should be a decent nerf to the over-performing “Spam Leonas” strategy and return our Leona production to normal values.
Ekko’s Patience was in some instances doing double the intended damage. Fixing the damage here and now is a riskier change, so we’re opting to disable it for the remainder of the patch allowing us to fix and more rigorously QA it.
- Fixed a bug where Arbiter could grant 2 triggers without Arbiter 3 active.
- Fixed a bug where Arbiter’s Economy triggered more often than intended.
- Ekko’s Patience (Artifact) has been temporarily disabled due to a bug.
- Fixed a bug where Varus’ Boon was granting the incorrect amount of health.

Ekko’s Patience was in some instances doing double the intended damage. Fixing the damage here and now is a lot riskier of a change than we’d want to do, so we’re opting to disable it for the remainder of the patch allowing us to fix and more rigorously QA it.

- Fixed a bug where Arbiter’s Economy triggers triggered more often than intended.

PATCH HIGHLIGHTS
SYSTEMS
GOD BOON
Only one God Boon to adjust this patch, as most of our changes are geared towards enabling new lines through champion/Trait buffs. But the change we do have is specific to the overperforming Anomaly Specialist role which performs exceptionally well in unint
