When HoYoverse unfurled patch 6.1 of Genshin Impact on October 22, 2025, collectors stepped into an unfamiliar financial theater. The Miliastra Wonderland Odes system did not simply add costumes; it installed a miniature gacha economy with its own currencies, conversion schedules, and expiration clocks. For players who have treated cosmetics as a side pursuit, the shift is akin to walking into a treasury where some vault doors require gold and others require keys that vanish at midnight.
The centerpiece of patch 6.1 is the Miliastra Wonderland Ode, the first large-scale cosmetic gacha in Genshin Impact's lifecycle. Unlike the familiar intertwined-fates system, this banner ecosystem splits into Standard and Premium tracks, each fed by different currencies. Understanding this architecture is now essential for every collector, especially since many rewards auto-convert or expire on strict timers.
The Six-Currency Framework
The Ode economy revolves around six currencies, each with distinct acquisition paths and lifespans.
Arcane Keystone
Serving as the premium pull currency for Miliastra Wonderland Odes, Arcane Keystone functions much like event fates do for character banners. Its acquisition path, however, is severely constrained in patch 6.1. The primary source is conversion from Chronal Nexus, the paid currency. Additionally, at the start of a new patch, unused Radiant Shards auto-convert into Arcane Keystones at a rate that yields five pulls per conversion. As of patch 6.1, no free-to-play pathway exists for earning Arcane Keystones—a detail HoYoverse has not addressed in official materials, though future events may introduce one.
| Source | Method | Rate |
|---|---|---|
| Chronal Nexus | Convert paid currency in-game | Primary |
| Radiant Shard | Auto-conversion at new patch start | 5 pulls per conversion |
| Events | Not available as of 6.1 | None confirmed |
Chronal Nexus
The top-tier currency of the Ode system functions as a real-money gate. Chronal Nexus is purchased in the in-game shop with actual currency—pricing varies by region—and cannot be spent directly. Instead, it must be converted in-game, mirroring the role Genesis Crystals hold in the base game economy. Like a golden river that only feeds the privileged garden, Chronal Nexus is the sole tributary that nourishes Premium Ode access in the current patch.
Geode of Replication
For players who prefer to keep their wallets closed, Geode of Replication is the free event currency tied to the Standard Ode banner. It is earned by completing event tasks, level-up rewards, and login events. Crucially, Geodes are only spendable on the Standard Ode and are invalid for Premium pulls. This currency represents the most sustainable path for non-spenders seeking cosmetic items, though it requires daily and weekly participation to accumulate meaningfully.
Star Token
Star Token functions as a personalized discount mechanism. It provides a 20% discount on a single Premium Ode pull for the player's own account and is non-transferable. The token is exclusive to the Miliastra Wonderland Battle Pass, titled Chronicles of the Realms. Notably, purchasing the standard Genshin Impact Battle Pass activates a Boon effect that discounts or grants the Wonderland Battle Pass for free during patch 6.1. Players should consider activating this after earning core free-to-play rewards for maximum efficiency.
Radiant Shard
Radiant Shard is the duplicate management currency for Premium 5-star cosmetics. When a player pulls the featured 5-star costume a third time or beyond in the Premium Ode, the duplicate converts to Radiant Shards. These shards can be exchanged for the rotating featured 5-star outfit of the current major patch. However, Radiant Shards carry a strict expiration: they auto-convert to Arcane Keystones if unused by the version's end.
Engraved Shard
For 4-star and 3-star rarities, Engraved Shard manages duplicates. A second or greater copy of a 4-star item on Event Ode yields five Engraved Shards, while each additional 3-star cosmetic generates one. These can be traded for relevant rewards in the current Ode shop, but like Radiant Shards, they expire at the version's end.
Currency Comparison Table
| Currency | Premium/Free | Primary Source | Expires? |
|---|---|---|---|
| Arcane Keystone | Premium | Chronal Nexus conversion | No |
| Chronal Nexus | Paid | Real-money purchase | No |
| Geode of Replication | Free | Events, logins, level-ups | No |
| Star Token | Paid (Battle Pass) | Chronicles of the Realms | Yes, per patch |
| Radiant Shard | Premium duplicate | 5-star duplicates | Yes |
| Engraved Shard | Free/Standard duplicate | 4-star/3-star duplicates | Yes |
Strategic Planning by Player Tier
For free-to-play and low-spending players, the core strategy is clear: treat the Standard Ode as the primary hunting ground and let Geode of Replication be the weapon of choice. Login events and daily tasks should be scheduled around the UTC+8 reset to maximize pulls without spending. The Star Token is technically attainable with a single Battle Pass purchase, but budget-conscious players should prioritize core account value over cosmetic vanity.
For spenders and collectors, the calculus becomes more intricate. Chronal Nexus should be reserved for targeted Premium pulls only if chasing limited exclusives is the goal. Duplicate outcomes, often seen as disappointing, actually gain strategic weight in this system: Radiant and Engraved Shards become valuable for maximizing shop redemptions before conversion. A spender who pulls duplicates is not simply losing; they are accumulating a second currency that must be spent before it evaporates.
Critical Deadlines
Time is the quiet antagonist of patch 6.1's cosmetic economy. The current major Ode runs from October 22, 2025, through approximately December 5, 2025, with exact dates subject to minor shifts. Several deadlines demand attention:
-
⏰ Radiant and Engraved Shards must be exchanged by patch end—hoarding them is a mathematical loss.
-
⏰ Star Token is valid only for the current Premium Ode and cannot be carried forward.
-
⏰ Unspent Radiant Shards auto-convert to Arcane Keystones at version end, while Engraved Shards simply expire.
-
⏰ Geode of Replication, by contrast, does not expire and can be carried forward.
-
⚠️ Star Token cannot be gifted or used on friends' Odes—it applies only to the player's own account.
The distinction between Standard and Premium banners is not merely cosmetic confusion; it is a fundamental fork in the road. Players must verify which banner they are pulling on before spending, as Standard and Premium currencies are not interchangeable.
Frequently Asked Questions
Can free-to-play players obtain premium costumes in patch 6.1? No. All Premium Ode pulls require Arcane Keystone, which is currently locked behind paid Chronal Nexus unless HoYoverse announces otherwise.
Do pity or guarantee rules apply to Premium Odes? Official materials have not stated specific pity mechanics. Players should assume pity likely operates similarly to weapon or cosmetic banners but must check in-game details each patch.
What happens to currencies after the patch? Geode of Replication does not expire. Radiant Shards auto-convert to Arcane Keystones, and Engraved Shards expire entirely.
Outlook
The Miliastra Wonderland Odes represent more than a new banner; they establish a parallel economic ecosystem that rewards planning and punishes procrastination. Navigating this system is like charting a course through a gilded maze where some corridors seal shut at midnight—those who understand the map walk away with exclusive treasures, while those who hesitate may watch their currencies dissolve into less valuable forms.
For future updates, including any potential free-to-play access to Arcane Keystone, players should monitor patch notes on early.gg. As the cosmetic gacha landscape evolves, the currency literacy gained in patch 6.1 will likely prove as valuable as any costume itself.
