Patch 25.05 introduces numerous changes to the game, including balance adjustments, a new lane swap detection mechanic, Arena updates, and significant changes to the Battle Pass reward system. It also accompanies the year's first major international tournament — First Stand. Let's break down the main innovations. Update details were published on the game's official website.

Main Changes
Battle Pass Updates and Rewards
Hextech chests replace free skins in the Battle Pass.
The cost of all champions for Blue Essence is reduced by 50%.
25 Mythic Essence is added to the paid Battle Pass instead of one skin.
Clash returns to a monthly schedule.
"Your Shop" returns in 25.06, and the "Blue Essence Emporium" in 25.07.
Key fragment consolidation: they now automatically round up to form a whole key.

New Lane Swap Detection System
To prevent early lane swaps in professional play, a mechanic is introduced that penalizes teams sending two champions without a jungle item to top or mid between 1:30 and 3:30:

Towers receive a 95% damage reduction.
Minions take 1000% damage from the tower.
Minions and towers transfer gold and experience to the nearest ally.
Champions breaking the rule lose 50% gold and experience from minions.
On top, the tower also deals 1000% damage to champions, and the defending champion receives a 50% damage reduction under the tower.
