Regular Maintenance
Regular Maintenance makes weapon and armor condition decay 50% slower; StrategyWiki lists it as a perk granted while Raul is a following companion.
How it works
Game8 lists Regular Maintenance as a companion perk and states that weapon and armor condition decays 50% slower. StrategyWiki says a companion following the player grants a perk, usually a minor bonus, and lists Raul with Regular Maintenance. The passages do not further detail duration or conditions for this benefit.
