Yes, too many have gotten burned doing this. Wait until you can upgrade the razor nets and do that. Do not waste them crafting Skullnados.
I'M guessing this is like Spirit Stag in VC, wasting a boss drop that can't further craft elite/leg? (Worst part, no reverse recipe LOL) Or Pyromancer that can make cheap, but no upgrade like Danm Elven Queen.
Yes it's one of those that many learned the hard way. Took a drop and crafted into something that you would out use and takes a long time to craft that many that you need to cover everything down to the bottom and getting enough free gifts to do it. Needless to say making them into elites and legendary would be better to do with the razor nets then making skullnados.
