As will all class mods from Tiny Tina's Assault on Dragon Keep, the Barbarian class mod will grant two of the following bonuses up to the specified amount, depending on the full name of the class mod:
- Accuracy: +35% ("Lawful" in the name)
- Critical Damage: +54% ("Evil" in the name)
- Fire Rate: +35% ("Chaotic" in the name)
- Magazine Size: +86% ("True Neutral" in the name) or +54% ("Neutral" in the name)
- Reload Speed: +35% ("Good" in the name)
The "True Neutral" class mod grants two separate Magazine Size bonuses and thus will display them as a single bonus. All others will display two distinct bonuses.
The Barbarian class mod will spawn with one of the following nine prefixes:
- Chaotic Evil
- Chaotic Good
- Chaotic Neutral
- Lawful Evil
- Lawful Good
- Lawful Neutral
- Neutral Evil
- Neutral Good
- True Neutral
Variants of the Barbarian class mod may grant the following bonuses up to:
- All "Good" variants of the Barbarian class mod were, at one point, bugged, lengthening the time taken to reload rather than decreasing it. This bug has been fixed, and the bonus now functions correctly.
- This class-mod was also available in a SHiFT code available on Gearbox's website, which could be found within a letter supposedly sent by Tiny Tina to Krieg. Similar letters were sent to all of the Vault Hunters.
- This mod was named for the Barbarian class found within Dungeons & Dragons, a game that was a prominent inspiration for the DLC.
