Planning Notes
Treat Undefined as a mythical target. If a native biome or breakthrough chance is listed, compare that context against your current luck before spending a long roll session.
For practical planning, open the rolling simulator to see roll feed context and use the calculator when you want cumulative chance from a specific luck setup.
