Matrices

Matrices (aka Chips) are weapon attachments that provide stat boosts and special effects.
By default the set effect only applies when using the weapon that the matrices are attached to, unless otherwise specified.
There are 4 slots on each weapon; Emotion, Mind, Belief, and Memory. Each of these slots gives slightly different passive stats.
Matrices can be strengthened similar to weapons, with each star unlocking higher values for the set effect.
