LoL Varus players will find him to be a dynamic character to build out properly. You will find that his build changes when he is up against either well-rounded or highly focused team comps, meaning you should not choose the same Varus build every single round of League of Legends
The best items to include in your champ's build are: Guinsoo's Rageblade, Bloodthirster, and Kraken Slayer. Players who included these pieces in their setups had a greater winrate than players who utilized other Varus builds. Likewise, if you are playing a varied enemy team comp, you should strongly consider getting yourself the Precision, and Domination runes. In recent matches, he won the greatest fraction of his rounds when equipped with these runes.
