Do bonuses on one weapon affect other weapons in Nier Automata?

For instance, when I have a weapon giving me "critical+" in the heavy attack slot; is it applied to my weapon in the light attack slot when I strike only with light attacks ?

Solution 1:

Throughout my research, it has noted a few times (here, here) that only non-combat specific weapons effect will apply regardless of which weapon is active. This is limited to two effects:

• Robot Discount
• Discount

Fortunately, these two effects do stack! So you'll get major discounts at some shots.

For combat specific weapon effects, this reddit has researched this a little bit. The users on that community have stated that they did not see a difference in weapon speed when they have two weapons with Attack Speed Up equipped as opposed to only having one weapon equipped.
