Class Mod (Borderlands 2)

Class Mods
A Gunzerker Class Mod

This article is about the Borderlands 2 class mods. For other uses, see Class Mod.

Class Mods, or COMs (short for Class Optimization Modules), are influential items in Borderlands 2. They are class specific upgrades that provide benefits to the character (or the entire team) by offering a wide variety of bonuses such as amplifying a character's damage, healing, increasing character health or shield capacity, reducing reload times, increasing skill ranks, etc. Class Mod skill bonuses do stack, even if a specific skill is maxxed (5/5), up to a total maximum of 11 ranks in any skill. A skill bonus however will not function unless the character has at least 1 point invested in the specified skill. Skills currently receiving bonuses from an equipped Class Mod are outlined in cyan in the skill tree, even if no points are invested in the skill.

Class mods can be obtained in several ways throughout the game.

• They can be bought from medical vending machines.
• Found in many of the lootable objects such as: Chests, skag piles or lockers.
• As a reward from completing a mission.
• Dropped by certain enemies when they are killed.

Borderlands 2 Class Mods

Class mods in Borderlands 2 have a prefix that will note the skills given by the class mod, with the prefix determining the mandatory focus of the skill bonus. Skills that are boosted by class mods will also be shown in the skill tree selection, listing the number of bonus points from the mod and the final percentages for the skill.

The prefix (if any) always offers a bonus to the skill that it is associated with, as shown in the charts below. (For example, Maya's "Hell Binder" class mod will always buff Helios, "Cunning Binder," Reaper, and "Chrono Binder," Suspension.) The additional skills that receive a bonus (if any) come from the class mod's pre-defined set of skills. (For example, Maya's "Binder" class mod will always affect only Helios, Reaper, and/or Suspension.)

Tiny Tina's Assault on Dragon Keep adds a set of class mods (Barbarian, Cleric, Monk, Necromancer, Ranger, and Rogue) which do not follow the above rule. The prefix on these class mods instead determines what player variables (e.g. Fire Rate, Magazine Size, etc.) are affected.

The rarity of a class mod determines how many skills it will affect:

• White - No skill bonuses
• Green - 1 skill bonus
• Blue - 2 skill bonuses
• Purple - 3 skill bonuses

"Legendary" and "Slayer Of Terramorphous" class mods each grant additional skill bonuses:

• Legendary - 5 or 6 skill bonuses, depending on class
• Slayer Of Terramorphous - 5 skill bonuses

The level and rarity of a class mod determine the number of bonus skill points granted. The maximum number of bonus skill points at maximum level by rarity is:

• Green - +5 skill points
• Blue - +6, +5 skill points
• Purple - +5, +4, +4 skill points
• Legendary - +5, +5, +5, +5, +5, (+5) skill points
• Slayer Of Terramorphous - +4, +4, +4, +4, +4 skill points

Class mods are visible on-character, seen as a signature piece of equipment on each of the characters. They are Salvador's digistruct ammo boxes, Maya's book, Axton's targeting device, Zer0's elbow blades, Gaige's lunchbox, and Krieg's sawblade.

Loyalty mods from Borderlands no longer exist. However, the new Allegiance Relics provide a similar function.

Alignment Class Mods

Alignment class mods are class mods only available in Tiny Tina's Assault on Dragon Keep campaign DLC. These mods give the Vault Hunters a Dungeons & Dragons-inspired title, in addition to granting bonuses based upon the mod's alignment (Chaotic Good, Lawful Neutral, etc.). Also, regardless of the listed alignment, these mods will always boost the same three skills for each character. Otherwise, they follow the same rules as regular mods as far as the number of skills boosted for the rarity.

Alignment Type	Affected Variable
Lawful	Accuracy (Up to 33%)
Chaotic	Fire Rate (Up to 33%)
Good	Reload Speed (Up to 45%)
Evil	Critical Hit Damage (Up to 45%)
Neutral	Magazine Size (Up to 45%)
True Neutral (Double instance of Neutral Alignment)	Magazine Size (Up to 86%)

Notes

• Blue-rarity Class Mods under level 50 cannot give more than +5/+4 to their skills. In order to give +6 to a single skill, a blue-rarity class mod must be at least level 50.
