Off the top of my head, I reduced my weapons down to 5.
+50% human damage Combat Rifle.
Maxson's Gatling Laser.
+10 plasma damage .50 Sniper Rifle.
+10 flame damage 10mm pistol.
Electrified Chinese Sword, consecutive attacks on enemy causes increasing damage.
And currently playing with an automatic laser rifle. I would like something useful to use my stockpile of Fusion Cells.
Also, most of this is fully upgraded, or most parts are fully upgraded.
Waiting on final blacksmithing perk to get the Electric Serrated sword, or find one for sale. Really dumb that you can learn to serrate a sword at perk 2, electrify at perk 3, but have to be perk 4 to serrate AND electrify.
