Increased Chest Loot

I’m seeing this on items, but I have yet to find a crafting material for it after thousands. Drop only?

Go do transmutations. I’ve got Loads of that one. It’s a rare craft material and there is a large list of rare crafts so chances to get as a drop is VERY slim. Transmutations are way to go

Must be bad luck, I just burned through 1000+ transmutes and I have yet to find 1/3 in lots of play time!

The material for it is the Magnification Lens, which have actually been temporarily removed from the game after they and Crippling Ointment caused some very serious bugs, I believe.
