Congratulations, LoL fans, on surviving the long, cold month of January and making it to the next stage of LoL patch 10.3 has now brought to the live game, we've got another sizeable round of tweaks and tinkerings on the PBE to share with you – it's time for League of Legends patch 10.4!
While the last update introduced some super sweet Heartseeker skins for Yuumi and Jinx – just perfect ahead of Valentine's Day – it looks like patch 10.4 is taking a slightly different direction with a return of the Blood Moon line. Three Champs get Blood Moon skins this update: Katarina, Master Yi, and Tryndamere. You can get a good look at these further down.
That's not all, however – Riot's got a whole bunch of balance top lane Soraka would be nerfed "pretty hard", and it looks like this is already on the way, with a load of changes to her abilities this patch. But she's not the only one – top lane Sona's getting nerfed too, judging by the changes Riot's made on the PBE so far.
There are also some Item and Rune changes to check out which, including pretty significant adjustments to Stopwatch and Perfect Timing. Read on to see what's in store for League of Legends patch 10.4 below.

Here's the splash:

LEAGUE OF LEGENDS PATCH 10.4 SCREEN
Every League of Legends patch has its own screen. They're usually great, and patch 10.4's is sure to be no exception. It's not clear yet what its theme might be, but with some new and spooky Blood Moon skins on the way, perhaps we could see these take centre stage – or it could be a Valentine's Day-themed screen featuring those Heartseeker skins. Guess we'll have to wait and see.
That's all we've got for League of Legends patch 10.4. You can stay up to date with the current version of the game via the LoLpatch 10.5 notes in the very near future, too.
