Hey, I crafted a UV of Spur sword today by accident (already have the sword but not UV) and then gave it to a friend for like 400 cr and 2 gel core. Now I'm reading in the trade forum people are asking for, for example, a UV Haze Bomb... which is the tier 1 bomb. Why are they asking for the low tier? I thought the fact that my UV Spur was only 2 stars that it wasn't worth much.

If I crafted the UV Spur into its next upgrade would it also have been UV? Is that why?

thanks
