All variants of the Blister class mod grant the following bonuses up to:

  • Grenade Capacity: +6
  • Kill Skill Duration: +66%


  • Diesel
  • Driven
  • Blood

Skill Bonuses

Variants of the Blister class mod may grant the following bonuses up to:


  • Grenades over the character's native capacity will vanish if the mod is removed.
  • The mod was glitched to increase Boiling Blood instead of Blood Bath and was fixed with September 25th hotfix.
  • The 25th September hotfix is glitched to boost Boiling Blood along with Blood Bath. A purple Blister mod will therefore boost 4 skill instead of usual 3.
