Understand Necramech Refuel
Useful when…
- Consider it when engine replenishment is a priority for your Necramech.
What it changes
The bonus rises from +5% at rank 0 to +15% at rank 2 and +20% at rank 3.
Fitting and ranking it
This standard Necramech mod has Vazarin polarity, a base drain of 6, and a maximum rank of 3. Fusion steps shown cost 10, 20, then 40 Endo and 483, 966, then 1,932 Credits. The last rank raises the listed bonus from +15% to +20%; weigh that increment against the fusion cost and the mod capacity it occupies.
How it differs from other engine mods
Necramech Efficiency lists +30% Engine Efficiency, while Necramech Thrusters lists +100% Engine Max. Those affect different named engine properties, so they are not direct substitutes for replenishment. Choose based on which property matters to your setup; the inputs do not establish how these bonuses interact.
Limitations and tradeoffs
- Uses a standard mod slot and has a base drain of 6.
- The rank 3 bonus is five percentage points above rank 2, at additional fusion cost.
Common mistakes to avoid
- Treating replenishment as engine efficiency or maximum engine capacity; the listed mods affect distinct properties.
- Assuming the supplied percentage tells you an exact amount or trigger for engine restoration.
