If you're working toward Irisalis in Aniimo, the one-time Petal sources aren't the only way to make progress. The Irisalis event also has three repeatable weekly sources that can provide up to 35 Irisalis Petals per week.
This guide focuses specifically on those weekly sources, their limits, their costs, and the weekly reset. For the complete list of permanent and one-time Petal sources, see our Aniimo Irisalis 99 Petals Checklist.
Quick Answer
You can get up to 35 Irisalis Petals per week from three repeatable sources:
| Weekly Source | Petals | Weekly Limit |
|---|---|---|
| The Faded Rainbow | 6 | 2 claims |
| Stamp Shop | 4 | 4 Petals |
| Breezy Mission Letters | 25 | 5 Letters |
| Total | 35 | Weekly maximum |
The three sources use different currencies, so getting all 35 Petals requires Primegy, Windborn Stamps, and Glimmer.
The weekly costs are:
- 100 Primegy for The Faded Rainbow
- 200 Windborn Stamps for four Stamp Shop Petals
- 2,140 Glimmer for five Breezy Mission Letters
The weekly limits reset on Monday at 4:00 AM.
Faded Rainbow: 6 Petals Weekly
The Faded Rainbow is one of the main repeatable Irisalis Petal sources.
You need to meet the activity's level requirement and spend 50 Primegy per claim. Each claim rewards:
- 3 Irisalis Petals
- 250 XP
- 20 Windborn Stamps
- 50,000 Coins
You can make up to two claims per week, giving you:
3 Petals × 2 claims = 6 Irisalis Petals per week
The two weekly claims therefore cost 100 Primegy in total.
The Faded Rainbow is useful if you're already spending Primegy on the event because it provides several additional rewards alongside the Petals.
Stamp Shop: 4 Petals Weekly
The Stamp Shop provides another repeatable way to obtain Irisalis Petals.
Each Irisalis Petal costs:
50 Windborn Stamps
The weekly limit is 4 Petals, giving you:
50 × 4 = 200 Windborn Stamps
That works out to 4 Irisalis Petals per week from the Stamp Shop.
Unlike The Faded Rainbow, this source doesn't require Primegy. Instead, you'll need to have enough Windborn Stamps available when the weekly allowance refreshes.
Breezy Mission Letters: 25 Petals Weekly
Breezy Mission Letters are the largest repeatable weekly source.
Each letter costs 428 Glimmer and guarantees a Prismatic Kite Flower. The flower provides 5 Irisalis Petals.
You can purchase up to five letters per week.
That gives:
5 Petals × 5 Letters = 25 Irisalis Petals per week
The total cost for five letters is:
428 × 5 = 2,140 Glimmer
Because this source alone provides 25 Petals, it makes up the largest portion of the weekly repeatable Petal total.
How Much Does 35 Petals Cost?
If you use all three weekly sources, the maximum is 35 Irisalis Petals.
The combined weekly currency cost is:
- 100 Primegy
- 200 Windborn Stamps
- 2,140 Glimmer
In return, you receive:
6 + 4 + 25 = 35 Irisalis Petals
The important distinction is that the 35-Petal figure is the maximum weekly repeatable amount, not a single free weekly reward. Each source consumes its own in-game currency.
When Do Weekly Petals Reset?
The Irisalis weekly sources reset on Monday at 4:00 AM.
This applies to the weekly allowances for:
- The Faded Rainbow
- Stamp Shop Irisalis Petals
- Breezy Mission Letters
If you've already used a source's weekly allowance, you'll need to wait for the next reset before purchasing or claiming it again.
35-Petal Weekly Routine
Once the weekly reset arrives, the full Petal allowance can be collected through three simple steps:
- Claim The Faded Rainbow twice — 6 Petals
- Purchase four Irisalis Petals from the Stamp Shop — 4 Petals
- Purchase up to five Breezy Mission Letters — 25 Petals
Weekly total: 35 Irisalis Petals
You don't have to use every source. Each one has its own currency requirement, so your actual weekly total depends on which allowances you use.

What Are Irisalis Petals Used For?
The main purpose of Irisalis Petals is progressing toward Irisalis, the legendary Aniimo introduced with the event.
You need 99 Irisalis Petals to obtain the Irisalis Aniipod.
If you're starting from zero, the weekly sources can provide up to 35 additional Petals per weekly reset, while the one-time sources provide another pool of Petals that does not depend on the weekly limits.

Floral Rainbow Feather
Irisalis Petals can also be used for the Floral Rainbow Feather, which costs 30 Irisalis Petals.
Its effect is:
Summoned clones deal 30% additional damage.
This gives Petals another event-related use beyond obtaining Irisalis.
Once you've unlocked Irisalis, you can also check our Aniimo Transmog Guide for details on the event's cosmetic system.
