About this Mod

This mod focuses on improving the number of slots available in the Curious mod. It adds 5 colors in total, which are neither easy nor difficult to obtain. Some Curious items are very powerful while others are not, but sometimes something is missing, so we added this extra slot to achieve our goal.
