Official game update
Avatar Legends July 29 Update Adds Keyboard Remapping
The first official post-launch update turns one launch priority into an available feature and adds cosmetic content plus unspecified fixes.
Short answer
The official July 29 post says the first post-launch update is available now. It lists keyboard control remapping, a Samurai Appa support-character skin, Deluxe Edition colors, and smaller fixes and improvements.
What does the official update confirm?
Keyboard control remapping is the clearest task-changing addition. The launch newsletter had listed Keyboard Mapping as an upcoming-patch priority; this newer official post now describes remapping as part of an available update. Players should use the current in-game settings to inspect the options provided by their own build.
The announcement also names the Samurai Appa support-character skin and Deluxe Edition colors. It does not explain unlock conditions, color allocation, menu paths, or platform differences, so this summary does not add those details.
What remains unspecified?
The developer refers only to a range of smaller bug fixes and improvements. The post does not publish a version number, itemized fix list, balance values, input table, or frame and damage data. It also does not say that Ranked Mode, Lobbies, or Spectator Mode shipped in this update. Those features should remain separate from what the July 29 announcement actually confirms.
