Starting at third level, you gain the ability to spend 2 ki points to enter a known stance as a bonus action. Whilst in a stance you gain certain benefits and weaknesses that enhance your abilities. You can spend a ki point to change to a different stance as a bonus action while in a stance or to exit a stance and revert to a normal state. Stances can be sustained for a number of minutes equal to your monk level, after which the spirit of the channelled animal disperses.
