I don´t see the point of new shields. All shields look unique and unconvenient. And so many weapons.
Some have the same origin. Spore.
Owl´s Eye, Eternity, Fog Shield and Sundial are definitely made with it. I think Discord, Trident, Arsenic too.
Carpace Shield ,Dimensional Shield, Skull Shield, Dissipation Shield could be from there.
Maybe even more. You can find them (more or less easily), if you click on the names in the login screen.
The art of the shields fits to the art of the weapon in my opinion.
The only shield which doesn´t really fit in my opinion is Hope, with a humanoid and the light.
It´s effect could be easily transferred to Solar Shield. But I think, this will not happen.
