Maintenance
Maintenance governs weapon upkeep and maximum equipment charge. GameBanshee says each level lessens nanite expenditure on maintenance, improves Disposable Maintenance Tool efficiency, and permits an additional 10% energy charge in equipment.
How it works
This is especially relevant if relying on implants, Energy weapons, or powered armor, because more charge can mean fewer portable batteries, electron cascades, or trips to recharge stations. The Skills & Upgrades guide also says level 4 permits maintaining every weapon and raises a weapon's maintenance level by four per tool use.
