In the new patch 25.S1.3, Riot Games introduced numerous changes affecting both champions and game systems on various maps. Here is a brief overview of the key changes for all major game modes.

Changes in Summoner's Rift

Champion Buffs:

Evelynn, Jax, Blue Kayn, Nasus, Quinn, Rakan, Samira, Swain, and Thresh received enhancements aimed at increasing their effectiveness in the current meta. This should make them more appealing for selection in different roles.

Champion Nerfs:

Cassiopeia, Galio, tank Jayce, Miss Fortune, Rell, Skarner, Teemo, and Viego were weakened. This is due to their dominance in recent updates and the need to balance their impact on the game.

System Changes:

Buffs affected elements such as the attack speed cap, Chemtech Soul, and Domination runes branch to strengthen aggressive play styles.

Nerfs targeted Bloodsong, Cloud Soul, Void Grubs, and Zaz'Zak’s Realmspike, reducing their excessive effectiveness.

Adjustments to the losing team's champion reward system will balance comebacks.

Changes in Swiftplay 

Champion Buffs:

Fiddlesticks, Nidalee, Ivern, and Zoe received improvements to make them stronger and more useful in the fast-paced game mode.

Champion Nerfs:

Yorick and Teemo became less powerful, due to their overly high effectiveness in current Swiftplay games.

System Changes:

Adjustment of the game pace to ensure the match lasts a balanced amount of time and remains tense until the end.

URF 

System Changes:

Increasing the attack speed cap will make battles even more dynamic and fast-paced, adding chaos to already rapid games.

Patch 25.S1.3 aims to diversify the meta, allowing not only new but also long-established champions to shine. The update promises significant changes that will be interesting for both newcomers and game veterans.
