The Superimposer in Honkai: Star Rail acts as a Free Light Cone and can be used to Superimpose one of the available Light Cones in Herta’s Shop. It can be used on the three Light Cones you see available for purchase with the same Herta Bonds as the Superimposer, it’s called the Custom-Made Superimposer.
If this seems a bit limiting, take a closer look at the Light Cones available, one for Destruction, the other for Preservation, and one for Hunting. Your main characters, the Trailblazer, March 7th, and Dan Heng, will be able to use these Light Cones as Free-To-Play Light Cones. In Warp Banners, you are not guaranteed to get the best light cones for your characters given the scope of the game. The game has made Five-Star Light Cones available for those who are willing to grind hard against the Simulated Universe.
If you’re missing a good Light Cone for your character, you’ll have options as a player who doesn’t want to break into their bank or hasn’t had luck on the Light Cone Banner.
