I've searched the forums that people wanted the fusion anvil, but the consensus is that it can't be implemented. How about, alternatively, create an NX cosmetic gear for every equipment in the game (and separating it into its own section I guess). Like I can buy an NX Fairfrozen for 3k NX or something like that. Would this be possible?
There are countless threads about this exact idea (this comes up in almost all the anvil suggestion threads.) I know there are more recent statements about it, but I'll link to one of Joong's posts, and more importantly see Matt's post below that one. There's a philosophical view point and a technical one (I cannot speak to whether the philosophy has changed, obviously.) Note this is from 2015. I remember @Sen giving a statement more recently about turning regular items into NX items, but I can't seem to find it. Link to aforementioned statements. I'm not entirely opposed to the idea, but perhaps it might have to be limited in scope.
