If you equip a piece of legendary armour onto a companion, do they get the benefits from that armour that you would normally get? Or would it just be a standard piece of armour to them? For example, I have a Combat Armor Right Leg that provides 15% less damage taken from humans. If I gave that to Piper, would she gain that benefit?
After some digging on Reddit with folks asking the same question, I found that your Companions DO benefit from most legendary armor effects. I need to emphasize MOST though as they obviously do not benefit from increased AP / VATS hit chance ect... they also do not benefit from (+) Resistance benefits. You can also upgrade companions armor with deep pockets and equip legendary gear with strength to increase their carrying capacities by a LOT (Paladin Danse or Strong could essentially be your pack mule slaves). I hope this info helped out!
I was surprised at the suggestion they don't benefit from resistances. The relevant quote from the linked discussion is "They don't benefit from +resistance mods. (I find this one weird and really hope it's a bug, unless I need to equip full set of given armour to get the listed bonus, player benefits from bonuses on per-piece basis)." That's not super convincing. I'm going to look for more evidence. Aug 29, 2016 at 18:30
Don't see any more after a couple minutes. Shouldn't be too hard to test though, even on console. I'll try to remember to do so: put legendary resistance (such as Poisoner's) armor on a companion, dismiss them, target them in VATS with the awareness perk, check. Aug 29, 2016 at 18:34
4I tested this last night. Putting a Poisoner's left arm on X6-88 gave him 25 poison resistance, as reported by Awareness. Aug 30, 2016 at 19:30
1A particularly annoying one, companions seemingly don't benefit from "acrobat" (50% less falling damage). My PC has two "acrobat" pieces, so I can jump from anywhere and take no damage. I put the same gear on Curie and either Piper or Cait, and they both managed to fall off a building and require stim-packing like 5 minutes later. I am using a bunch of mods, including one that allows crafting legendaries, so it may be a bug with my game, rather than a default behavior.– MichaelSSep 9, 2016 at 9:00
Chameleon armor pieces do not give them the chameleon effect while standing still. Sep 22, 2016 at 4:28
I regularly equip and use chameleon armor with my companions. Occasionally I need to unequip and re-equip it for it to continue to work
