I put on a solar glaive today with a sword to do the lost sector and was going to use Mediveal champion to get an overload and unstop mod. When I loaded in neither the sword nor the glaive had the champion perk. When I remove the sword the glaive gets the unstoppable perk and works fine. It seems to be situational. I tested multiple things: With strand subclass and Final warning equipped it all shows up just fine. Strand subclass everything showed up properly until I equipped something else with an overload perk and then the overload disappeared. I had a bow (Verglas) in my primary slot with an overload artifact mod selected. I equipped Bastion. The overload came back on the sword and still remained on both the glaive and the fusion. Void Subclass submachine gun with overload from artifact and sword equipped. Sword does not have overload. Put a glaive on and a sword and only the glaive registered champion perk. Equipped final warning and unstop shows on glaive and barrier on pistol but nothing on sword. Took glaive off and exchanged for a pulse and the overload showed up on the sword. Put the glaive back on and it went away.
