Basics of Customization
 Tweaking the Tools of the Trade
Though leveling the weapon levels for each character largely determines just how useful they will be with the three weapon types, customizing the weapons themselves can help further unlock their potential. Only handguns and machine guns can be customized by attaching additional components to the weapon body itself in the customization screen. Each of these component categories affects one or more of a weapon's key attributes:
 Charge Speed
Basic actions that target either an enemy or player must complete at least one Charge on the on-screen targeting cursor to execute properly. The speed at which a Charge is completed for attacks on enemies depends on two key factors: the player's distance from its target during the Charge, and the Charge speed stat of their equipped weapon(s). A higher Charge speed stat essentially allows players to complete a Charge sooner at a greater distance from an enemy.
 Charge Acceleration
Attack effects are increased the more Charges a player manages to accumulate on the targeting cursor before finally committing to the attack on an enemy. Leveling a character's proficiency with a weapon allows them to unlock more powerful effects, but these require additional Charges equal to the level at which they learned the attack effect. A weapon's Charge acceleration rate determines just how fast subsequent Charges are built after the initial Charge is complete. Coupled with the increased Charge speed that results as players close in their target, higher acceleration allows more Charges to be built much faster, meaning more powerful attacks in a shorter period of time. It comes into its own during Hero Actions, when players can attack more than once as their character travels along the set path.
 Rate of Fire
This stat is only really factored when the party enters Critical Condition as a result of losing all their Hero Actions on the Hero Gauge. The party enters a panicked state during Critical Condition, and their attacks are greatly reduced against the opposition. The effectiveness of any attack which characters attempt to make in Critical Condition is determined by Rate of Fire, as they are reduced to firing random, blustering shots against targets. Defeating any enemy allows the party to recover from this highly disadvantageous state of affairs, regaining a single Hero Action.
This refers to a weapon's Accuracy, determining how many of the bullets fired during a single attack hit home on the target, further affecting the Scratch/Direct Damage inflicted.
 Magazine Size
The Magazine Size is a given weapon's current max ammo count. This determines how many bullets are fired by a character when they commit to an attack, which directly affects the number of hits a character can make against a target during a single attack. Characters will always attempt to fire the maximum number of bullets available to them; these bullets are automatically replenished for the next attack. Note that the number of bullets fired is NOT effected by the number of Charges accumulated. Unless they are equipped with a Magazine Case filled with special ammunition, characters don't actually run out of bullets during battles.
The component categories and what they actually affect during weapon customization are as follows:
- Scopes / Sights - Charge Speed
- Barrels - Charge Acceleration
- Hand Grips / Mounts - Focus & Rate of Fire
- Bullet Magazines - Magazine Size
The more of each component is attached to a given to a weapon, the greater the effects they bestow on its attributes. Note that attached components seen in the Customization screen do not ever appear in-game on the weapon itself, for good reason; powerful weapon builds often incorporate a high number of components in arrangements which would never be considered realistic even by video gaming standards.
