You have a strong inner tranquillity which strengthen your physical body. You gain the following benefits:
- You gain 2 Ki points and recover all of your Ki points at the end of a short or long rest. If you already have Ki points you instead gain 3 more.
- When you would be knocked backwards or prone you can use your reaction and expend 1 Ki point to prevent the effect from occurring.
- When you are forced to make a Constitution saving throw you can use your reaction and expend 1 Ki to gain advantage on the saving throw.
This feat serves two purposes: Provide some interesting defensive reactions, and allow monks to gain additional Ki. The second reaction was intentionally made to be no use for a monk once they have access to Diamond Soul (14th level), to make the feet a non-requirement.
