So I would like to make a mask of the shapeshifter for my original character. Everything I've read says to combine a source point with flayed faces. I have the face skins. I have source points. I still can't craft it. What am I missing? The crafting specifically says source orb, but I haven't seen those in game. I've only ever gotten source from pools or using purging wands.

Can anyone give me some insight as to what I'm doing wrong?
