Expertise is a Tier One Skill in Axton's Gunpowder tree. It increases Axton's Weapon Swap Speed and Aim Speed. Also, Axton's Movement Speed is increased while aiming.

Expertise is boosted by the Legendary Soldier and Slayer of Terramorphous class mods. This skill has interesting synergy with the weapon Greed, which allows normal run while aiming. With enough points in Expertise, aiming with Greed can allow Axton to run much faster than sprint speed.


  • Weapon Swap Speed Speed: +14% per level
  • Aim Speed: +14% per level
  • Movement Speed: +7% per level (Only while aiming)


Level 1 2 3 4 5
Weapon Swap Speed +14% +28% +42% +56% +70%
Aim Speed +14% +28% +42% +56% +70%
Movement Speed +7% +14% +21% +28% +35%


  • The Greed pistol from Captain Scarlett and Her Pirate's Booty prevents movement loss when aiming. With several points in Expertise, Axton can actually move faster than sprint speed while using this pistol. This is espescially pronounced with a maxed out Expertise with the Slayer of Terramorphous or Legendary Soldier mods.
