Understand Exposing Harpoon

Useful when…

  • Harpak loadouts where an enemy can be pulled before using the temporary bonus

Trigger and bonus

Pulling an enemy triggers a 15-second Critical Chance bonus: +100% at rank 0, +200% at rank 3, and +300% at rank 5. These are the listed bonus values, not a final Critical Chance.

Using the duration

The stated bonus lasts 15 seconds after an enemy is pulled.

Limitations and tradeoffs

  • Compatibility is limited to the Harpak.
  • The bonus requires pulling an enemy and lasts 15 seconds.
  • Higher ranks increase the bonus and require more fusion resources.

Common mistakes to avoid

  • Assuming the Harpak itself performs the pull.
  • Reading the listed bonus as a final Critical Chance value.
  • Assuming the bonus is active before an enemy is pulled.
