Smoke Bomb You can spend 1 ki point to throw a smoke bomb. It functions the same as the Fog Cloud spell with the following changes - It lasts a number of rounds up to your Intelligence modifier (You determine the duration when you make the bomb), its range is 30’ rather than 120’, you may shrink the radius up to a single 5' space, and is not a spell for the purpose of counterspells or antimagic zones. When you reach 9th level, you can spend an additional ki point to upgrade it into Poisonous Smoke Bomb. You are immune to the poison and any creature that ends its turn or enters the smoke for the first time during its turn must make a Constitution saving throw or be poisoned for 1 minute. At the end of each of its turns, the target can make another Constitution saving throw. On a success, they are no longer poisoned. If the size of the cloud has been reduced to a 5' space, the DC increases by 2.

Ki Cut You can spend 1 ki point to attempt to Cut the ki flow on a target’s body. When you hit a creature, they must make a Constitution saving throw. On a successful save, nothing happens, though you may try to use this feature again when you can. On a failed save, the creature has a penalty to their attack and damage rolls equal to your proficiency bonus, as well as a saving throw of your choice. In addition, any ki related features the creature may have cannot be used until the end of your next turn and you don't need advantage on the attack roll to use your Sneak Attack against the creature as long as you don't have disadvantage on the attack roll. All the other rules for Sneak Attack still apply to you. When you reach 9th level, you can spend an additional ki point to upgrade it to Ki Sever. You add an extra D4 to the save DC and penalty.

Mask You can spend 1 ki point to blend in to your surroundings. you have advantage on Stealth checks until the end of your next turn. At 9th level, for an additional ki point you can upgrade it to Blend. You can attempt to hide even when you are only lightly obscured. This includes cover from foliage, heavy rain, falling snow, mist, and other similar phenomena.
