Do Alpha Aniimos reward Irisalis petals?

Claiming the petal from an Alpha does not consume any of your energy. Subsequent clears of that same Alpha Aniimo will not grant another petal, making each beast a one-time payout.

These rewards build directly toward Irisalis. Crafting the legendary Windchase Departure Anapod requires 49 Iris Petals, and you can also find eight Irisalis petals gathered directly across the open world map.

Petals also function as event currency. Glimmering Driftshadow can be purchased from the Walking with Irisalis Legendary Journey event store for two petals each.
