Patch 25.21 is shaping up to be quite massive.

The last couple of patches in League of Legends were relatively small compared to others, largely due to Worlds 2025. Now that the Worlds patch is out, Riot is yet again making sweeping changes.

Starting off with the changes, champion buffs. A bunch of champions are getting buffs, including the marksmen, Ezreal, Graves, Kalista, and Yunara. As for nerfs, Diana, Morgana, Qiyana, and Quinn are getting nerfs. There are also some adjustments to Bard, Gwen, Dr. Mundo, and Skarner.

Finally, one of the biggest changes coming to Patch 25.21 is the changes to starting items, specifically Doran’s items. All three of the Dorans’ items are getting adjustments, making them better offensively while nerfing sustain. They are also further nerfing sustain by changing the rune Second Wind and the item Catalyst of Aeons.

Aside from these, there’s also a bunch of other changes coming in this patch. So, we have a lot to cover, so let’s get into it.
