Crystalline Circuit
The Crystalline Circuit is an upgrade material in Arknights, introduced alongside Episode 08.
A core product in the modern Originium electronics industry. Found inside electronic goods far and wide throughout Terra's nations. The mass application of crystalline circuitry is one more reminder of Terra's industrial modernization.
Usage
The second of the Crystalline-type upgrade materials, Crystalline Circuits are a printed circuit board that integrates a Crystalline Component and used as a major component by various Originium-based electronic appliances in Terra. Crystalline Circuits are used in the skill Mastery training and Elite 2 promotion of certain Operators introduced from Episode 08 onwards.
The Crystalline Circuit is obviously a required material for the production of Crystalline Electronic Units.
