The Stamp Shop is a menu-based store inside Aniimo’s Season Hub where you trade Windborn Stamps for limited weekly materials and larger seasonal rewards. It is not an in-world vendor you walk up to, which is why it can be easy to miss. Once you know the menu path and how the two tabs work, it becomes a reliable way to top up progression materials every week.
Quick answer: Open the Season Hub (press F1 on PC), choose Stamp Shop in the lower-left, then use the Weekly tab for Monday-reset materials or the Season tab for spend-gated rewards.
Where to open the Stamp Shop
How to earn Windborn Stamps
Windborn Stamps are the seasonal currency for this shop during Departure with the Wind. You cannot buy them with Credits or premium currency, so they come entirely from playing seasonal activities. There are three main sources.
| Source | Stamps earned |
|---|---|
| Daily Activity Quests | Up to 10 per day |
| Stamp Rush (weekly event) | Main weekly source, capped at 1,000 per week |
| Companion Handbook above level 70 | 20 per level, plus 30 more with the Advanced Edition |
The Stamp Rush is the heaviest source. It runs weekly and lists tasks across categories such as Aniimo activities, Combat, Egg Heist, and Homeland. Completing them fills your stamp balance quickly, but the 1,000 stamp weekly cap means there is no benefit to grinding past it in a single week.
Weekly Stamp Shop items and limits
The Weekly tab holds progression materials with a per-week purchase cap on each. These are the items most worth clearing before the reset, because the materials are harder to replace than plain Credits.
| Item | Cost | Weekly limit |
|---|---|---|
 Irisalis Petal | 50 Stamps | 4 |
 Vein Essence | 50 Stamps | 10 |
| Breezy Plains Dewdrop Crystal x20 | 30 Stamps | 10 |
| Flux Crystal | 30 Stamps | 5 |
| Star Dust x5 | 20 Stamps | 10 |
| Credits x2,000 | 1 Stamp | No limit |
Vein Essence feeds nurture progression and is one of the shop’s recommended buys, while Flux Crystals act as universal evolution and enhancement materials. Irisalis Petals matter if you are pushing toward the Legendary Irisalis route and have already used up easier Petal sources. Star Dust and Dewdrop Crystals cover training and regional upgrades.
The Credits x2,000 line has no purchase limit, but treat it as a fallback. Credits have many other sources, so spend stamps on the capped materials first and only convert leftovers into Credits.
Seasonal milestone items
The Season tab works differently from the weekly stock. Each reward stays locked until you have spent a cumulative amount of Windborn Stamps across the shop, and reaching that threshold does not hand you the item. You still pay a separate stamp cost to buy it.
| Reward | Stamps spent to unlock | Purchase cost |
|---|---|---|
| Sparkling Egg | 300 | 200 |
 Sparkling Cube | 2,500 | 500 |
| Flameplated Dragon Shield | 3,500 | 600 |
 Prismana Orb | 7,000 | 900 |
 Phenomena Crystal | 11,500 | 1,500 |
Several Starcryst Essence bundles and Capafruit also appear on the Season tab at their own spending tiers, and an extra Sparkling Egg unlocks higher up the ladder. Because you must watch two numbers at once, the unlock threshold and the purchase price, protect enough stamps for any big reward you are targeting before spending the rest each week.
When the Stamp Shop resets
The Weekly tab resets every Monday at 04:00 (UTC+8), restoring the weekly limit for each item. The Season tab runs on a different timer and updates when a new Part of the season starts, so the Monday reset leaves the spend-gated unlock ladder unchanged.
Parts use different stamp names. Part One’s Windborn Stamps do not carry over as spending currency into Part Two, which uses Windchaser Stamps. Spend a large Windborn Stamp balance before the Part ends rather than holding it.
A purchase has gone through when the item lands in your bag and the weekly limit counter for that line drops by one. For seasonal rewards, the reward moves from locked to purchased once you meet both the spend threshold and pay its cost.
Weston, the daily Mysterious Vendor
Alongside the Stamp Shop, a separate daily vendor named Weston sells rare training items for Credits rather than stamps. His stock rotates every day and can include Starcryst Essence, Psyche Fruit, which changes an Aniimo’s personality, Growth Fruit, and various Anipods.
You will find Weston on Chill Street near Horizon Square in Astra. Open the World Map, switch to the Astra view, and look for the purple Mysterious Vendor marker, then speak to the large white creature to browse his daily stock.
Between the Stamp Shop and Weston, the routine that saves the most time is simple: clear the capped Weekly materials before Monday reset, hold back stamps for any Season reward you want, and check Weston each day for the Credits-only items you actually need.
