The Ring of Instinct also completed and in-game. That just leaves the Ring of Bloodlust and Enchanted Ring left to do. Now the hard part, actually coming up with a design for both (that's what eats up the most time!) All gems have multi-layer parallax by the way!
The gem on this ring isn't actually smooth like the image suggests, it's got some random facets but I didn't get a good position with the lighting (and my current computer hates 1440p)
