Anomaly Proficiency, is a stat that enhances the damage inflicted by Attribute Anomalies. Each point in Anomaly Proficiency is equivalent to 1% of Attribute Anomaly DMG.

Agent Stat Calculation[]

Most stats (ATK, HP, DEF, Impact, Anomaly Proficiency, Anomaly Mastery, Energy Regen) start with a base value, and can be further increased by bonuses. Base value is gained naturally when Agents and W-Engines are leveled, as well as from leveling up Core Passives.

Stat bonuses are divided into two categories: unconditional bonuses (e.g. stats from Drive Discs, secondary stats of W-Engines) and conditional bonuses (e.g. buffs provided by Agent skills, set bonuses of Drive Discs, buffs from eating at the Noodle Shop). When a character enters combat, all unconditional bonuses are first applied and stats are frozen. When additional in-combat bonuses are gained, they use the frozen stats as base.

In general, agent stats are calculated as follows:

For the remaining stats (CRIT Rate, CRIT DMG, PEN, Pen Ratio, DMG Bonus), all bonuses are additive.

Sources of Anomaly Proficiency[]

The following Drive Discs and W-Engines are sources of Anomaly Proficiency:
