主な変更点

Input and output pools were rebuilt

Arbiter

Check Arbiter options more often before defaulting away; the trait should present fewer dead rolls.

Items are no longer narrow locks

Psionic

Psionic starts can flex between AD, AP, and utility holders more comfortably.

Dark Star 6 down, several traits up

Traits

Do not assume Dark Star emblem caps outrun the lobby; Challenger, N.O.V.A., Sniper, Space Groove, and Stargazer lines need testing.

Aatrox, TF, Bel'Veth, Zoe, Aurora, and MF gained power

Reroll

Reroll is more clickable when shops, items, and augments align, but contest still matters.

Corki down, Morgana/Nami/Xayah adjusted

Four-costs

Level 8 boards should spread items more deliberately instead of blindly chasing Corki.

Artifacts and radiant items moved

Items

Blighting Jewel, Luden's Tempest, Yasuo's Bladework, and radiant defensive options deserve fresh priority checks.

Fun and economy augments were lifted

Augments

Exalted Adventure, Booster Pack, Timestream, and Heart of the Swarm are stronger signals than before.

Arbiter Emblem buffed, Rogue Emblem nerfed

Emblems

Spatula decisions should lean less on Rogue as a generic carry solution.

Systems and Gods

17.4 is not a systems overhaul, but the few system changes do affect opener greed and God selection.

check_circleEkko's Specialist Boon star damage was reduced, so the no-item anomaly tech is less of an automatic spike.
check_circleChest of Greed is disabled because of a bug, removing one high-variance God Offering from the pool.
check_circleChoncc's K.O. Coliseum prismatic breakpoints for Star Guardian and Soul Fighter are harder to reach.
check_circleBug fixes clean up Morgana's cost tooltip, Nunu revive edge cases, Master Yi targeting, Samira passive triggers, and several trial or Double Up issues.

Traits and Arbiter

The trait pass is the core of 17.4: more playable patterns, fewer dead offerings, and a Dark Star cap check.

check_circleArbiter now guarantees one input from each broad category and one output from offense, defense, and economy pools.
check_circleChallenger, N.O.V.A. 5, Sniper's higher breakpoints, Space Groove 7, and several Stargazer patterns received buffs.
check_circlePsionic items are more flexible, and Target-Lock Optics now scales for either AD or AP champions after first damaging enemies.
check_circleDark Star 6 bonus power and mini Dark Hole health were reduced, especially important for emblem-heavy caps.

groups

Unit reshuffle

The patch brings back several low and mid-cost carries while shaving the most contested late-game defaults.

check_circleAatrox and Twisted Fate buffs help one-cost reroll and Stellar Combo boards when the opening actually supports them.
check_circleBel'Veth's last-patch nerf was partially reverted, while Gwen, Zoe, Aurora, Miss Fortune, Ornn, and Viktor were improved.
check_circleMorgana moved to one range and gained more shield scaling, making her job as a frontliner clearer; Nami casts faster and Xayah hits harder.
check_circleCorki and Fiora were trimmed, Graves received a base attack speed buff, and Shen and Zed had first-cast timing adjusted.

extension

Augments and items

Item and augment changes push players toward broader planning instead of a few default combat spikes.

check_circleShieldmaiden, Self-Destruct, Reach for the Stars, Hard Commit, Hold the Line, Group Hug, Kahunahuna, and Sweet Treats were weakened.
check_circleOne Two Three, Booster Pack, Charge Transfer, Climb the Ladder, Exalted Adventure, Heroic Grab Bag, Heart of Steel, Heart of the Swarm, Luxury Subscription, and Timestream gained value.
check_circleRadiant Adaptive Helm, Radiant Dragon's Claw, Radiant Guinsoo's, and several Artifacts were buffed, while Radiant Gargoyle and Radiant Nashor's Tooth were reduced.
check_circleArbiter Emblem gives more attack speed now, while Rogue Emblem's omnivamp was cut sharply.

insights

パッチ結論

特性

アービターが読みやすく

入力と出力のプールが整理され、アービター構成を諦める前に確認したい選択肢が増えました。

アイテム

アイテムの受け先が増加

サイオニックとアーティファクトの調整で、完璧な一人に依存しない装備ルートが取りやすくなりました。

テンポ

リロールラインに追い風

エイトロックス、ツイステッド・フェイト、ベル＝ヴェス、ゾーイ、オーロラ、ミス・フォーチュンなどは条件が合えば狙いやすくなりました。

メタ

旧定番は再評価

ダークスター6、コーキ、フィオラ、ローグの紋章、一部戦闘オーグメントは以前ほど自動選択ではありません。

ランク前チェック

1序盤にアービターが見えたら、入力/出力の組み合わせを確認してから継続判断しましょう。
2サイオニックアイテムは一人に固定せず、AD、AP、ユーティリティ持ちまで広く見ます。
3エイトロックス、ツイステッド・フェイト、ベル＝ヴェス、ゾーイ、オーロラ、ミス・フォーチュン、オーン、ビクター、ナミ、ザヤが多い時は転換サインです。
4ダークスター6、コーキ、フィオラ、ローグの紋章、弱体化された戦闘オーグメントはメタが落ち着くまで慎重に評価しましょう。
5正確な数値とホットフィックスは Riot 原文を確認し、このページは何を使うか、いつリロールするかの判断に使ってください。
