League of Legends Swain players could find him to be a complex champ to build out properly. You'll find that his build changes when he is playing against either generic or specialized team comps, indicating you should not choose the same Swain build every game of League of Legends
The most critical items to include in your champion's build include: Liandry's Anguish, Rabadon's Deathcap, and Shard of True Ice. Those who included these pieces in their setups had a much higher win rate than players who utilized other builds for Swain.
