I am going to be making the mercurial demo set with these uv's and I was wondering what it would be worth crowns wise.

Heavy Demo Helm: Increased shadow defense: Medium (Got at 3*) and Increased Normal Defense: Low (Got at 3* version as well) (For now)
Heavy Demo Suit: Increased Freeze Resistance: Medium (Got at 3*) and Increased Elemental Defense: Maximum! (Got at 3* version as well) (For now)
