Why Perpetual Engine is uncommon
Rarity is earned, not assigned. Every word is ranked by how deep in the recipe graph it sits and how few paths reach it, then the ladder is cut by percentile: common, uncommon, rare, epic, legendary, mythic. Perpetual Engine sits 33 fusions from the starting quad. How the world works.
