Way of the Cat's Grace

In the feline kingdom, nimbleness and nobility reign. From the smallest house cat to the strongest lion, cats are born with a certain amount of this grace. It is this fact that allows the monks of the Way of the Cat's Grace study their craft. Meticulously studying the movement and purpose of these creatures is what gives them the tools to dominate in battle. And rest much too long. It is what it is.

Cat Nap

You have studied the art of the cat nap to regain stamina. Once per long rest, you can take a 30 minute instead of a 60 minute long rest. You can add your proficiency bonus to all hit dice rolled during this short rest. Additionally, during each long rest, you can choose to take a 12 hour instead of an 8 hour long rest to gain 8 + WIS + Proficiency temporary hit points. These hit points reset at the beginning of your next long rest. If you do not use this feature at least once after 3 regular long rests, you gain one point of exhaustion. 

Kitty's Pounce

At 6th level, you have pounced with your fellow cat brethren too many times to count. During your movement, you can choose to leap up to double your normal jump distance as a free action, as long as you land on an enemy. You immediately spend a ki point, and deal 3 unarmed strikes rather than the usual two you spend on a fury of blows. As an action, you can choose restrain the creature on the ground. You have advantage on the opposed athletics check to do this.

Cat's Vicious Venom

When you reach 11th level, you have had so much venom injected in your veins that not only are you resistant to poison, but are able to use it against your foes. You gain resistance to poison damage and advantage on poison saving throws. When you make an unarmed attack, you can spend two ki points to force an enemy to make a constitution saving throw. On a failure, they are poisoned, and take 3 d6 additional poison damage from the attack. On a success, they are not poisoned, and take half damage. They can repeat the save at the end of each of their turns. You can spend two more ki points to deal an additional 2 d6 poison damage, and you can do this up to 9 d6 damage. You can only use this feature once per turn. 

Cat Form

At 17th level, your love for cats manifests itself both spiritually and physically. Once per long rest, as an action on your turn, you immediately are effected by a wild-shape turning you into a tiger or lion. You immediately gain 1/4th your maximum hit points in temporary hit points, you can use all abilities granted by your form, use your humanoid mental stats and dexterity, and use all your ki abilities. This lasts one hour. At the end of the hour, you lose the temporary hit points if any remain, and you gain one point of exhaustion.
