Piercing Caliber

Rifle Puncture damage mod

Released Nov 27, 2014

Piercing Caliber adds Puncture damage to a rifle. Consider it when increasing that damage type on a rifle is useful to your weapon setup; its bonus is a portion of Puncture damage, not a general increase to all rifle damage.

Piercing Caliber GUIDE

Understand Piercing Caliber

Useful when…

  • Add Puncture damage to a compatible rifle.
  • Choose a Puncture-focused standard rifle mod.

Effect and compatibility

The standard Rifle mod has Naramon polarity and base drain 6. It adds +20% Puncture at rank 0, +80% at rank 3, and +120% at rank 5. The listed bonus is specifically Puncture damage; it should not be read as a +120% increase to all damage or as final damage.

Ranking and alternatives

Piercing Hit is a Common standard rifle mod with the same Naramon polarity and a lower base drain of 4, listing up to +90% Puncture. Flawed Piercing Hit is a Flawed variant with a lower listed maximum of +12% Puncture and base drain 2. These alternatives trade listed bonus and drain; neither changes Piercing Caliber’s own rank effects.

Investment and limit

The mod reaches rank 5. The listed rank 4-to-5 step costs 480 Endo and 23,184 Credits. It occupies a standard rifle mod slot, so weigh that investment and slot against other effects you could fit. Ripper Rounds is a Conclave variant describing conversion of 20% of damage into Puncture, not the same standard-mod bonus.

Limitations and tradeoffs

  • Targets Puncture damage rather than all damage.
  • Higher ranks require additional fusion resources and mod capacity.
  • The Conclave conversion mod is a different variant and effect.

Common mistakes to avoid

  • Treating +120% Puncture as +120% total rifle damage.
  • Confusing the standard mod with the Conclave damage-conversion variant.
