Client Release: 0.5.1 'Shields Up!'

[Maroon]

• Two extremely high tier engineer items, Master Weaponsmith's Anvil, and the Master Shieldsmith's Anvil. The weapon anvil improves weapons to masterwork quality, while the shield anvil improves shields to reinforced quality. Please note that while they do change the quality of deployables and/or health kits, they do not actually improve their effects/scene props, and that they will take every weapon/shield you have equipped of the same type, so drop your extra weapons/shields before attempting to smith.
  

I don't really get how these work. So, you drop those anvils in-game, and people can upgrade their weapons and shields? Is this permanent or temporary?
