LoL Viktor players could find him to be a dynamic champion to build out properly. You'll notice that his build is modified when he is up against either generic or homogenous team compositions, meaning you shouldn't take the same Viktor build every game of League of Legends
The most critical items to use in your champ's build are: Ludens Sturm, Rabadons Todeshaube, and Fluch des Lichs. Those who added these pieces in their builds had a better win rate than players who worked towards other item builds for Viktor. Moreover, if you are playing a mixed enemy team composition, you should really consider grabbing Viktor the Inspiration, and Zauberei runes. In recent games, he won the largest number of his matches when equipped with these runes.
We established our Viktor build recommendations by analyzing 101.821 recently ranked League of Legends matches with him selected. We only advise the highest winrate Viktor builds that were used by ranked LoL players enough times for us to suggest them. With so many matches in our dataset, we are confident in our suggested builds.
