This was a quick and fun little build. I kept wondering how I was going to get the gem's point right, until I realized that the extrude feature could also leave a nice tapper. The bands that seem to hold the crystal in were a little tricky, with the outer-most bands having a weird geometry. I'll come back to this one in a bit to fix it, but for now, here it is. I'm working on modeling the other charms fro Hollow Knight, so check out my page to see what I've been working on!
V2 Update: I noticed that a few holes formed when slicing in Cura, so I went back to Fusion, fixed the issue, and reuploaded it as Quick Focus Charm - Fixed.
A charm containing a crystal lens.
Increases the speed of focusing SOUL, allowing the bearer to heal damage faster.
Any, but probably crystal purple if you want that crystal effect
NOTE: I made the mistake of not making my charms to scale in Fusion360, so the models are pretty small. If you scale it up by 300-320%, you'll get a decent size of about 5cm in diameter.
