Necramech Streamline

Necramech Streamline increases Ability Efficiency on a Necramech.

Released Aug 25, 2020

Necramech Streamline increases Ability Efficiency, reaching +30% at rank 5. Consider it when Ability Efficiency is the property you want to improve on your Necramech; it does not describe a bonus to duration, hover efficiency, or engine efficiency.

Necramech Streamline GUIDE

Understand Necramech Streamline

Useful when…

  • Increase the listed Ability Efficiency on a Necramech.
  • Choose rank investment according to how much of the listed bonus is useful for the build.

Effect and rank progression

The listed bonus is +5% Ability Efficiency at rank 0, +20% at rank 3, and +30% at rank 5. The effect is Ability Efficiency; no ability-specific energy savings are given, so those should not be inferred from the percentage alone.

Slot fit and fusion investment

This is a standard Necramech mod with Naramon polarity, base drain 4, and maximum rank 5. Listed fusion examples are 30 Endo and 1,449 Credits for 0→1, 120 Endo and 5,796 Credits for 2→3, and 480 Endo and 23,184 Credits for 4→5. Rank 3 already lists +20%; the final two ranks add the difference to +30% while the last example step carries the largest listed cost. Compare that additional bonus with your available capacity and resources.

Keep similar mod names distinct

Necramech Continuity lists +30% Ability Duration, Necramech Drift lists +60% Hover Efficiency, and Necramech Efficiency lists +30% Engine Efficiency. These are different properties from the Ability Efficiency increased by Streamline; select based on the property you intend to affect.

Listed acquisition

The supplied drop entries include Necramech (Tier 3) at 0.2%, and Isolation Vault and Arcana Isolation Vault entries across rotations A, B, and C. The listed vault chances vary by entry from 4% to 8%; these details do not guarantee current availability.

Limitations and tradeoffs

  • Rank 5 reaches +30% Ability Efficiency, but takes more fusion resources than the earlier listed steps.
  • It uses a standard mod slot with base drain 4 and Naramon polarity.

Common mistakes to avoid

  • Confusing Ability Efficiency with Ability Duration, Hover Efficiency, or Engine Efficiency.
  • Assuming the listed Ability Efficiency percentage specifies an exact energy saving for a particular ability.
