April 2026 Inventory by Rotation
Dates | Items | Price | Daily Cap |
|---|---|---|---|
April 3 to April 5 | Temperature Ball (调温球), Wonderful Ball (美妙球) | 7,500 Roco Shells each | 100 each |
April 10 to April 12 | Thermal Ball (热感球), Wonderful Ball (妙奇球) | 7,500 Roco Shells each | 100 each |
April 17 to April 19 | Transformation Ball (变幻球, Illusion and Mechanical coverage) | 3,000 Roco Shells | 200 per day |
Prices on the April 17 rotation reflect the April 16 Magic Renewal patch's weekend condition ball cost cut from 7,500 to 3,000 Roco Shells. The Transformation Ball rotation also doubled the daily purchase cap compared to earlier weekends.
May 2026 Inventory by Rotation
Dates | Items | Price | Daily Cap |
|---|---|---|---|
May 8 to May 10, 2026 | Photosynthesis Ball (光合球) - tuned for Grass-type spirits | 3,000 Roco Shells each | 200 per day |
The May 8-10 rotation pairs with the Gorgeous Grass (奇丽草) outbreak window for efficient capture of the Grass-type spawn group. The 200/day cap and 3,000 Roco Shell price track the post-April-16 Magic Renewal patch pricing, confirming the cheaper weekend ball economy is now the standing rule rather than a one-off.
Rotation Cadence Rule
Each Wandering Merchant rotation pairs with a concurrent outbreak window, so the ball type stocked predicts the wild-spawn type for that weekend. Players can read the next merchant restock as a hint about which spirit family is about to outbreak.
Item Types
Temperature Ball (调温球): Condition ball tuned for Fire and Ice type spirits.
Wonderful Ball (美妙球 / 妙奇球): Condition ball tuned for Normal and Cute category spirits. Exact translation varies by rotation.
Thermal Ball (热感球): Condition ball that triggers on warm-biome spirits.
Transformation Ball (变幻球): Condition ball tuned for Illusion and Mechanical type spirits. Introduced in the April 17 rotation.
All condition balls can also be synthesized at an alchemy station. After the April 16 patch, the synthesis recipe dropped from 1 Normal Gulu Ball plus 2 crops plus Roco Shells to just 1 Normal Gulu Ball plus 1 crop.
