A new leak from Honkai: Star Rail is teasing the special buff players will be able to utilize during Version 3.3's cycle of the "Memory of Chaos" game mode. The HoYoverse sci-fi RPG features a wide variety of different endgame challenges for players to tackle, ranging from pure tests of players' characters to unique combat setups. "Apocalyptic Shadow" pits players against powered-up versions of some of the game's toughest bosses, while "Pure Fiction" prioritizes quickly clearing waves of smaller enemies. However, one particular combat challenge has been around since the game's inception.
