I have yet to see any Titon treasure cards from my garden. The drop rate is extremely low. Why are these cards so rare? If receipes require them, the treasure card needs to be readily available. Make either the treasure card receipe available or change the item crafting to a craftable card. There is no good reason for the discrimination. You can't rely on luck of the draw for the card to drop. All the others are craftable or mob dropped. Make your storm wizards happy instead of frustrated. Centaurs are craftable why not Titon.
