League of Legends Viktor players will find him to be a challenging champ to build out properly. You will notice that his build is modified when he is playing against either well-rounded or highly focused team compositions, meaning you shouldn't follow the same Viktor build every round of League of Legends
The most critical items to use in your champ's build include: Affliction de Liandry, Coiffe de Rabadon, and Fléau de liche. Players who included these pieces in their setups had a much higher winrate than those who tried for other item builds for Viktor. Likewise, if you are facing a varied enemy team comp, you should really consider grabbing Viktor the Inspiration, and Sorcellerie runes. In recent games, he won the largest fraction of his rounds when built with these runes.
We calculated our Viktor build recommendations by analyzing 53 905 recently ranked League rounds with him selected. We only recommend the highest winrate Viktor builds that were used by ranked League players enough times for us to reccomend them. With so many rounds in our data, we are quite confident in our suggested builds.
