In many parts of Tian Xia, it’s tradition to mint coins with holes in the centers for the purpose of being able to thread a cord through them and tie them off for security and ease of transaction. This immaculately braided red cord is made in this tradition and can hold up to 100 coins at any given time. As long as you carry a
fortune cord, you gain a +2 item bonus to skill checks to
Earn Income.
If you load up to 100 coins onto a
fortune cord as part of your daily preparations, you can Activate the magic item in two different ways until the next time you make your daily preparations, provided all the loaded coins are of the same type.
