Secondary stat: Anomaly Proficiency
Whenever a squad member inflicts an Attribute Anomaly on an enemy, the equipper gains a buff that increases Anomaly Proficiency by 30/34/38/42/46, stacking up to 4 times. This effect expires when the target recovers from Stun or is defeated. The duration of each stack is calculated separately.
