A new Elden Ring patch is now live on all formats, fixing a bug introduced in the previous patch that tweaked one boss more than intended.

The 1.03.3 patch, which must be downloaded to play online, fixes a bug in the balance adjustment of Starscourge Radahn introduced in the 1.03 patch that made some of the boss' attacks less powerful than originally intended. Being a minor patch, this is everything new the 1.03.3 patch introduces, according to the official patch notes.
