[Alchemy Course] Challenge: Elixir of Swiftness

Eileen suggests making an Elixir of Swiftness, though the materials are a bit tricky to gather. Craft the Elixir of Swiftness, then speak with Eileen.

※ Use the Shared Alchemy Tool at Olvia Academy, or the alchemy tool in your residence.
※ Add only the ingredients needed for one batch of Elixir of Swiftness. Use "Batch Production" to produce multiple batches.
※ Elixir of Swiftness Ingredients: Legendary Beast's Blood x1 + Arrow Mushroom x5 + Powder of Darkness x2 + Birch Sap x5
※ Each Alchemy attempt should use ingredients for a single batch only.
※ Forfeiting this quest resets your progress. Materials obtained from Zaaira's Material Support cannot be reissued, so proceed with caution.
