Ruinous Extension

Pistol beam-range mod

Released Oct 24, 2014

Ruinous Extension adds up to 8 meters of beam range to a compatible pistol. Consider it when extra reach is useful for your beam weapon and you can spare a pistol Exilus slot.

Ruinous Extension GUIDE

Understand Ruinous Extension

Useful when…

  • Extend a pistol beam’s listed range.
  • Use it in the Exilus slot when range utility is more useful to your setup than another option.

What does it change?

The beam-range bonus is +2 m at rank 0, +6 m at rank 2, and +8 m at rank 3. It changes range, not damage.

Slot and compatibility

Ruinous Extension is a standard pistol Exilus mod with Naramon polarity, base drain 2, and maximum rank 3.

Ranking tradeoff

The final step from rank 2 to 3 costs 80 Endo and 3,864 Credits for 2 m more range. Rank it according to how much that additional reach matters to your use; the mod does not compete with standard-slot damage mods for the same slot type.

Limitations and tradeoffs

  • Uses an Exilus slot and investment for range rather than a listed damage bonus.

Common mistakes to avoid

  • Expecting the mod to increase damage or fire rate.
  • Ignoring that it occupies an Exilus slot.
