Do shields have level cap or something?
Example:
I own a Volcanic Plate Shield. We all know it's Normal Defense goes all the way up (i think it's maximum.) Now I've had on it a Normal Defense: High UV.
Does it make a difference? Should I roll for another UV? I mean, the damn shield's Norm DEF is already insanely high. Or does it have a level cap so no matter how I get like a Max Norm DEF the UV is just useless?
