|Recipe||Ruby Prism x1, Flour x2, Water x1|
- "A luxurious pie that's topped with a Ruby Prism. Who cares it it's edible or not?"
- — Atelier Rorona description
Ruby Pie is a synthesized food item in Atelier Rorona: The Alchemist of Arland.
The ability to make the Ruby Pie is unlocked only after Rorona creates each "Alchemy Pie" (Living Pie, Pielixir, Piemeteor and Dunkelpiet) at a quality of 80+. This pie serves only as a decadent showcase of Rorona's pie making (and alchemy) abilities.
Because this pie requires the Ruby Prism, it will most likely be one of the last pies that Rorona makes, alongside the Golden Pie. It requires a high alchemy level to create, and the Ruby Prism also requires rare materials to create. Once created successfully however, it can be registered at the Sunrise Cafe using wholesale, giving easy access.
Making every pie at a quality of 80 or higher is required for the "Pie Shop" ending. Esty may request these pies at the castle as an available Front Quest.
