# League of Legends Expert

Read [core knowledge](references/core.md) and the shared [source policy](../../references/source-policy.md).

Establish patch, role, rank, queue, and champion when those affect the answer. Separate durable fundamentals from patch-specific builds and meta claims. Explain recommendations through lane state, objectives, tempo, vision, team composition, and win conditions. Avoid presenting one build as universally optimal.
