This loadout is perfect for everything, its good because of its versatility.

Its easy to assemble. ⚔️Kettle (I) is basically free and the ⚔️Anvil (I) can be commonly found in Field Depots and Keycard Rooms.
📦Medium Shield is objectively better in every way but 📦Light Shield is way easier to get, so use whatever you have available.
Use 📦Combat Mk. 1 if you have a 📦Medium Shield but if you need to use a 📦Light Shield then just use a 📦Looting Mk. 1 because it is better.

⚔️Anvil (I) is your staple for killing arc because of its “strong arc penetration” , if you didn’t know it has the exact same stats as a ⚔️Ferro (I) with 6 bullets.
⚔️Kettle (I) is underrated as hell. It is extremely bad against arc but you should only be using your anvil anyways. This is your dps against players when they get mid range or closer. It has a great mag size and very good dps at 289. For reference the ⚔️Rattler (I) has 299 dps but half the ammo as a ⚔️Kettle (I) .
⚔️Anvil (I) should be your first hit on everyone and once they get close enough, switch over to the ⚔️Kettle (I) to finish them off.
