Necramech Efficiency

Necramech movement-efficiency mod

Released Nov 19, 2020

Necramech Efficiency raises Engine Efficiency, reaching +30% at rank 5. Consider it when you use your Necramech’s engine movement often and want to improve that specific efficiency stat. It does not increase hover or slide efficiency; those are handled by separate mods.

Necramech Efficiency GUIDE

Understand Necramech Efficiency

Useful when…

  • Use it to improve Engine Efficiency on a Necramech when engine movement is a regular part of your play.

What does it improve?

This standard Necramech mod gives +5% Engine Efficiency at rank 0, +20% at rank 3, and +30% at rank 5. The supplied effect does not define the underlying engine mechanic or translate the bonus into a specific duration or distance, so treat it as an efficiency increase rather than a guaranteed movement-time figure.

Which movement style benefits?

The mod is for engine efficiency specifically. Necramech Drift instead increases Hover Efficiency by 60%, while Necramech Friction increases Slide Efficiency by 60%. These affect different movement actions, so consider them according to whether engine movement, hovering, or sliding is the behavior you want to support; the alternatives are not direct replacements for this stat.

How should you rank it?

It has five ranks, a Vazarin polarity, and base drain of 4. Rank 0 gives +5%, rank 3 gives +20%, and the maximum rank gives +30%. Fusion costs rise across the listed steps: the 0-to-1 step costs 20 Endo and 966 Credits, 2-to-3 costs 80 Endo and 3,864 Credits, and 4-to-5 costs 320 Endo and 15,456 Credits. If you want a useful partial improvement while conserving resources, rank 3 is a stated milestone; invest in the final ranks when the extra Engine Efficiency matters to your setup.

What should you avoid confusing it with?

Necramech Refuel adds +20% Engine Replenish, a separate effect from Engine Efficiency. Do not assume this mod replenishes engine resources, or that it improves hovering and sliding.

Limitations and tradeoffs

  • The effect is limited to Engine Efficiency; hover and slide efficiency have separate mods.
  • Ranks 4 and 5 require higher listed fusion costs for the increase from +20% at rank 3 to +30% at rank 5.

Common mistakes to avoid

  • Treating Engine Efficiency as the same effect as Engine Replenish.
  • Expecting this mod to improve hover or slide efficiency.
