Composition

Composition denotes a mixture composed of two or more elements. The term refers to any material or substance that is not a single pure element but instead consists of multiple elemental components combined together.

A composition contains at least two distinct elements and can include more than two. It is the standard way to describe multi-element materials within the game's terminology, distinguishing such mixtures from single-element substances. The concept of composition applies whenever elements are present together in a combined form rather than existing individually.

• A composition is defined by the presence of two or more elements.
• The term contrasts with a single-element substance, which consists of only one elemental type.
• Compositions are identified by listing or otherwise representing the constituent elements that make up the mixture.
• The minimum element count for a composition is two; there is no upper bound implied by the definition.

Languages across the game's documentation express the same meaning: a mixture of two or more elements. The concise definition emphasizes only the numerical and combinatory aspect — that compositions are multi-element mixtures — without prescribing a particular arrangement, ratio, or form for those elements.
