When following this monastery you become more than a mortal; you become a vessel for the untamed power of four primal animal spirits. When tapping into the spirits' bestial natures, you can harness their unique strengths: The tiger grants him speed and ferocity, the turtle resilience, the bear might, and the phoenix its eternal flame. With their combined power, you can turn back all those who would attempt to harm the natural order.

By choosing this monastery you inherit the powers of the four primal animal spirits, when assuming one of their stances you let the spirit of your choice empower you giving you bonuses in combat. 

 

This tradition uses something called "Stances" which follow a specific set of rules;

A stance is active until you die, go unconscious or activate another stance. As a bonus action, you can spend 2 ki to activate any of your stances.

Effects from your stances all disappear when switching to another stance.

Tiger Stance

Also immediately after you take the Attack action on your turn, you can spend 1 ki point to cast the Inflict Wounds spell, this spell is cast at a level equal to your proficiency bonus halved (rounded down).
