LoL Patch Notes 25.S1.3 Preview (15.3)
Riot’s Lead Game Balance Designer Matt Leung-Harrison (@RiotPhroxzon) has shared an early preview of potential changes coming in Patch 25.S1.3. These adjustments give us a glimpse into what Riot’s balance team is considering for the next update.
The preview outlines notable champion adjustments, with particular attention to attack speed mechanics and bounty system modifications. Most significantly, we’re seeing potential base stat adjustments across multiple champions and a possible increase to the global attack speed cap from 2.5 to 3.0.
However, it’s important to note that none of these changes are final – they represent the current direction of internal testing and discussion.
