Arknights Wiki

Manganese Ore is an upgrade material in Arknights.


A metal ore used for metallurgy. Can be used for a variety of upgrades and for production in the Factory.

A metal that is used to produce a catalyst widely used in industries. As the reprocessing is complicated, accidents caused by nonstandard techniques do happen from time to time.


The first of the Manganese-type upgrade materials, the name does not actually refer to the metal ore, but rather the namesake element fused to it known for its dangers when handled incorrectly. With careful usage, though, Manganese Ore is essential for Operator advanced skill upgrades and Mastery training, and the Elite 2 promotion of 4★ and 5★ Operators.
