Wu-Gui Combination into Fire (戊癸合火)
Understand the Wu–Gui stem pair, the heat, season, roots, and continuity required for Fire transformation, and the evidence that keeps Earth and Water active.
Overview
Wu–Gui Combination into Fire (戊癸合火) pairs Wu Earth with Gui Water and proposes Fire as the transformed phase. The pair first establishes a relation; Fire transformation requires convincing seasonal, rooted, and climatic support. Strong Water or Earth roots, cold or wet conditions, competition, distance, and clashes can prevent transformation.

Require heat, roots, and seasonal permission
