Idle Slayer - Expensive Piece of Armor 

I had 72 Jewels of Soul when this item became available. I had to open about 130 dragon eggs to get the 38 jewels that I needed. I started to record the egg openings, but I decided that would be long and boring, so I stopped that.
I was looking for the campfire at the end of the video. I gave up before realizing it was under the portal menu.
