Core Skill are Combat Skills that provide passive effects for Agents. There are two types of Core Skills: Core Passives and Additional Abilities.

Core Passive

An Agent's Core Passive is separated between stat bonuses and a passive buff to one of the Agent's combat skills or abilities, provided certain conditions are met. The Core Passive will start with baseline buff values and no extra stat bonuses, and can then be levelled from through using Denny and materials from both the Expert Challenge and Notorious Hunt game-modes.

Starting from , the Core Passive will provide stat bonuses, alternating between a stat deemed useful to the Agent, based on their Attribute, Specialty, or play-style, and then usually a flat bonus of 25 Base ATK, with the only exception being Core Passive: Grandmaster of Mysticism, which gives a flat 140 Base HP instead. Each increase in the rank of the Core Skill will also provide higher values to the skill or ability buff.

Additional Ability

An Additional Ability is a Skill that is available to both Agents and Combat Bangboo. It provides a passive buff to either a specific stat, or specific skill, provided that the activation requirements are met. These activation requirements vary depending on the Agent or Bangboo, however typically revolve around the player's squad having another unit of the same Faction, same Attribute, or a specified Specialty.

Additional Abilities cannot be levelled to increase the bonuses they provide.
