Curio Synthesis is a new system that allows you to merge Curios in the Divergent Universe of Honkai: Star Rail. See what Curio Synthesis is, how to perform it, and where it is in this guide!

How to Perform Curio Synthesis

Merge Two Curios of The Same Rarity

To perform Curio Synthesis, you need to merge two Curios of the same rarity together. The resulting Curio will be a Curio of a higher rarity! Each synthesis allows you to pick one out of three random higher rarity Curios.

The highest rarity that you can obtain through Curio Synthesis is a 3-star Curio. Negative Curios cannot be used in Curio Synthesis, so plan accordingly.

Workbench of Creation in Escapade Domains

Curio Synthesis can only be accessed and done in Escapade Domains, through the Workbench of Creation. Keep in mind that there's a limited number of times a Workbench of Creation can perform Curio Synthesis, so use it wisely!
