The Orirock Cluster is an upgrade material in Arknights.

Description

A conglomerate rock mined from the ground. Can be used for a variety of upgrades and for production in the Factory.

Compressed from Orirock Cubes, it can be formed naturally. It is a fragile material, but industrial technology has made it possible to produce complete Orirock Clusters now. People often mistake it for an ordinary cluster of rocks.

Usage

The third of Orirock-type upgrade materials and made up of several Orirock Cubes whether through artificial or natural means, Orirock Clusters have a much greater energy yield and is 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 Orirock Clusters on 4-6 if one needs them to process Orirock Concentration.png Orirock Concentration due to it being a special drop there.

It is highly recommended to process Orirock Clusters (by farming Orirock Cube.png Orirock Cube on 1-7) if one only needs them since doing so is more Sanity.png Sanity-efficient than directly farming Orirock Clusters.
