Errata Update

The first errata update is out. I needed to make some clarifications throughout the Playbook Talents. I added an example in the Healing section and some charts in the Stuff chapter. Those changes necessitated relevant updates to the reference documents. Also, the character sheet at the end of the book needed to be fixed. This update fixed all the known bugs to this point. If you find anything else that needs to be added to the changelog, please give me a shout!
