Piercing Step

Warframe Exilus mod

Released Jul 31, 2015

Piercing Step improves parkour speed and airtime, and adds Puncture on Bullet Jump. Consider it for mobility and movement-triggered utility in a Warframe Exilus slot.

Piercing Step GUIDE

Understand Piercing Step

Useful when…

  • Increase Parkour Velocity and Aim Glide/Wall Latch Duration.
  • Add Puncture to Bullet Jump when moving through nearby enemies.

What does Piercing Step do?

At maximum rank, it grants +18% Parkour Velocity, +18% Aim Glide/Wall Latch Duration, and +60% Puncture on Bullet Jump. At rank 0, those values are +3%, +3%, and +10% respectively.

When should you consider it?

Its movement bonuses suit a setup that values faster parkour and longer aim glide or wall latch. The Puncture bonus applies on Bullet Jump, so it is tied to that movement action rather than a general weapon damage bonus.

Rank, polarity, and slot

This is an Uncommon Exilus mod for Warframes, with Naramon polarity, base drain 4, and a maximum rank of 5. Rank raises all three effects; rank 3 grants +12% parkour velocity, +12% aim glide/wall latch duration, and +40% Puncture on Bullet Jump. The last listed upgrade step costs 320 Endo and 15,456 Credits, so weigh the full-rank movement gains against the resources required.

Choosing the Bullet Jump effect

Battering Maneuver keeps the same maximum parkour and airtime bonuses but adds Impact on Bullet Jump. Firewalker and Ice Spring list larger parkour and airtime bonuses, with Heat or Cold on Bullet Jump respectively. Those are distinct effect choices; the supplied descriptions do not establish that any one is universally preferable.

Limitations and tradeoffs

  • Consumes an Exilus slot.
  • Its Puncture bonus is specifically tied to Bullet Jump; it does not apply as a general weapon bonus.

Common mistakes to avoid

  • Expecting the Puncture effect without using Bullet Jump.
  • Confusing the Exilus movement mod with a standard weapon damage mod.
