League of Legends Rammus players will find him to be a difficult character to build out properly. You'll find that his build is modified when he is playing against either diversified or highly focused team compositions, indicating you shouldn't follow the same Rammus build every game of League of Legends
The most critical items to incorporate into your champion's build include: Jak'Sho, le Protéiforme, Égide solaire, and Lithoplastron de gargouille. Those who added these pieces in their builds had a significantly better win rate than players who tried for other builds for Rammus. Similarly, if you are fighting a varied enemy team composition, you should strongly consider getting Rammus the Volonté, and Précision runes. In recent matches, he won the largest fraction of his games when built with these runes.
