Mostly bug fixes and addition of things that should've been in the game at launch.
Avatar Legends: The Fighting Game got a pretty rushed launch this month, with the company announcing that some of the core features will be making their way after release.
With the first patch, some of that is starting to shape up, as it mostly fixes bugs and presents a default feature of almost any PC game in the last roughly 40 years as a Quality of Life feature.
Alongside rebindable keys, it also adds some cosmetics, like Deluxe Edition colors for Steam users and the Samurai Appa support-character skin.
One of the unmentioned parts of the improvements is also adding a normal quick reset button instead of having to hold down 4 buttons at the same time.
