League of Legends Rengar players will likely find him to be a dynamic character to build out properly. You'll notice that his build is modified when he is up against either generic or homogenous team comps, showing you should not follow the same Rengar build every single game of League of Legends
The best items to use in your champ's build include: Dämmerungsklinge von Draktharr, Blutdürster, and Klaue des Meuchlers. Those who included these items in their builds had a much better winrate than players who utilized other builds for Rengar. Likewise, if you are trying to beat a mixed enemy team comp, you should really consider grabbing yourself the Dominanz, and Inspiration runes. In recent matches, he won the largest fraction of his matches when built with these runes.
