Oriron

Oriron
CN name	异铁
Type	Upgrade material

Oriron is an upgrade material in Arknights.

Description

A rare industrial material. Can be used for a variety of upgrades and for production in the Factory.

In a small number of inerting processes, Oriron Shards may have phase changed and polymerized into Oriron. It is generally thought that Oriron is relatively stable when it reaches this level.

Usage

The second of the Oriron-type upgrade materials, these Terran iron alloy are more stable than Oriron Shards, making it more valuable and is especially important in the intermediate upgrades of many Operators' skills and their Elite 1 promotion.
