Class Mods

Class Mods, or COMs (short for Class Optimization Modules), are influential items in Borderlands: The Pre-Sequel. 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). 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:

Borderlands: The Pre-Sequel Class Mods[]

Class mods in Borderlands: The Pre-Sequel 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. The additional skills that receive a bonus (if any) come from the class mod's pre-defined set of skills.

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 class mods each grant additional skill bonuses:
  • Celestial - 6 skill bonuses
  • Eridian Vanquisher and Chronicler of Elpis - 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
  • Celestial - +5, +5, +5, +5, +5, +5 skill points
  • Eridian Vanquisher and Chronicler of Elpis - +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.
