Advancements

Threads are how we count experience in Demigods. If you save up five Threads you can buy an Advancement from the list on your Playbook, but you can't hold more than five at a time.

On the list of Advancements, you can only check each box once, so choose wisely. You have to take five above-the-line Advancements before you can take anything below-the-line.
