Philosopher's Stone

Item from Fullmetal Alchemist by Hiromu Arakawa

A crimson stone forged from concentrated human souls that amplifies alchemical power beyond natural limits and bypasses the law of Equivalent Exchange — the most coveted and most horrific creation in alchemy.

Appearance

A deep crimson stone that glows with an inner light, ranging in size from a small gem to a large crystal depending on the number of souls it contains. Liquefied forms appear as viscous red fluid. It pulses with energy when activated, and those sensitive to it can hear the screaming of the souls trapped inside.

Also known as: Philosopher's Stone, The Red Stone, The Fifth Element, The Grand Elixir

What They Know

• Created by sacrificing living human beings and condensing their souls into a crystalline form
• Bypasses Equivalent Exchange by using the trapped souls as fuel for transmutations that would otherwise be impossible
• Every Homunculus is powered by a Philosopher's Stone at their core, granting them regeneration until the souls are depleted
• Tim Marcoh created Stones using Ishvalan prisoners during the genocide — research that Edward later uncovered
