When you look at an legionmate's action tab you see Artifacts under it as if there exists an artifact that benefits others. This got me thinking that there should be such an artifact.

These artifacts would allow legion members an ability to assist legionmates more than just repairs, credits, and gifting artifacts. It would create a stronger sense of interdependence.

Anyone have any ideas for artifacts under this category?

maybe a hack protection program artifact that counterhacks the player hacking your buddy using your stats

It would be nice if you could use any of the send/sharable arts directly on a legionmate who has something similar to the can be repaired flag turned on. For example having the ability to set a kvt or use a nano on them so if you were going to repair you could also set the traps up for them, it could be set to require them to be disabled first so you didn't allow the whole legion to throw kvts when someone is being hit but that way it has less chance of hurting a legionmate for those going for the repair medal.
