Most powerful items in League of Legends are built from smaller, cheaper 'component items'. These components provide smaller stat boosts and often have unique passives that contribute to the final item's effects. Understanding which components build into your desired items allows for efficient gold spending and power spikes. For example, a B.F. Sword builds into many AD items, while a Needlessly Large Rod builds into many AP items. Prioritize buying components that give you the stats you need most at that moment, or that complete a key passive effect.
