Inner Resilience 2014

Your internal discipline gives you access to a small pool of ki points. You gain the following benefits:

Increase your Wisdom score by 1, to a maximum of 20
You have 3 ki points, which you can spend to fuel the Patient Defense or Step of the Wind features from the monk class. When you spend a ki point, it is unavailable until you finish a short or long rest, at the end of which you draw all of your expended ki back into yourself. You must spend at least 30 minutes of the rest meditating to regain your ki points
If you already have ki points, your ki point maximum increases by 3 instead.
