Companions+Mods

[Malconis]

I haven't been able to find anything on this anywhere, and I need to know: If certain weapon mods, like Hush, are placed on a companion, do those effects carry over to all the warframe's weapons, or only to the companion? I'm currently using Taxon because of the obvious vaccuum utility, but I can't tell if the Hush mod I have installed on it actually helps or not.

It'll apply to the weapon it's applied to. In your specific example, Taxon's Artax laser will be silent, but your weapons will still be as loud as they normally are. If you want to silence your weapons, you'll have to apply it to your own weapons. Note that your weapons and Sentinel weapons cannot share the same mods, so if you want it for both you'll have to have two copies of it
