Oriron Cluster is an upgrade material in Arknights.

Description

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

During the processing, influenced by very few unartificial factors, multiple Orirons may merge into this form by chance. Its hardness has decreased but its purity has increased.

Usage

The third of the Oriron-type upgrade materials and made up of several Oriron that are fused during its smelting process by chance, Oriron Clusters are more valuable and is therefore used for many Operators' advanced skill upgrades and Mastery training, and the Elite 2 promotion of 4★ and 5★ Operators.

As seen on the table above, it is recommended to farm Oriron Clusters on S4-1 if one needs them to process Oriron Block.png Oriron Block due to it being a special drop there.

It is highly recommended to process Oriron Clusters (by farming Oriron.png Oriron on S3-3) if one only needs them since doing so is more Sanity.png Sanity-efficient than directly farming Oriron Clusters.
