The monks of this tradition, better known as the Snake Style, studied the techniques, strategies, form, and attributes of snakes, applying their fundamentals to martial arts. Monks of this style don't necessarily move in a serpentine fashion, as the goal isn't simply to imitate the animal, but to use it as inspiration for their techniques. This style is packed with flexibility and, above all, quick and precise attacks aimed at the target's sensitive points. Users of the Snake Style tend to attack as quickly and as early as possible, but they aren't necessarily reckless; they quickly analyze the enemy for weak points and are often very focused. There are also more patient ones who wait to strike at the right moment, catching their opponents by surprise.

Level 3: Snake Implements

You can be as stealthy and flexible as a snake. You gain proficiency in the Stealth skill. You also have advantage on ability checks and saving throws against the grappled and restrained conditions (both to avoid and escape).

Level 3: Snake Style Adept

You've trained to be quick and accurate. You can add your Wisdom modifier to your initiative rolls if you couldn't already.

Furthermore, your unarmed and monk weapon attacks in melee score a critical hit on a roll of 19 or 20. However, attacks guaranteed by your Flurry of Blows score a critical hit on a roll of 18 to 20.

Finally, you can't be surprised while you are conscious.

Level 6: Flexibility Against Obstacles

The snake's flexibility allows it to pass through obstacles more easily. Your unarmed and monk weapon attacks ignore the AC bonus granted to other creatures by half-cover and three-quarters cover.

Additionally, you can fit through spaces one size category smaller than you without squeezing.

Finally, during the turn you used your Step of the Wind, passing through non-magical difficult terrain doesn't cost you extra movement.

Level 6: Take Advantage of the Openings

You seek not to waste an opportunity when it presents itself. When you attack a creature that hasn't yet taken a turn in the current combat or attack as a reaction, you can roll a Martial Arts die and add the result to the attack roll.

Level 11: Snake Lunge

The snake prepares to deliver its deadly strike at just the right moment. Once per turn, you can spend 1 ki point to deal 4 Martial Arts dice of extra damage to a creature you hit with an unarmed strike or a monk weapon in melee, if you have advantage on the attack roll. You don't need advantage on the attack roll if another (non-incapacitated) enemy of the target is within 5 feet of it, the target is surprised, or the attack is from a Ready action, and you don't have disadvantage on the attack roll. If the attack is from a Ready action, you don't need to spend the ki point.

Additionally, other creatures provoke an opportunity attack from you when they enter your reach.

Level 17: Reactive

Your reaction and opportunistic abilities have reached their peak. You gain the following reaction-related benefits:

• You can use a reaction once per turn, instead of once per round.
• The range of your unarmed and monk weapon attacks in melee for opportunity attacks and other reaction attacks increases by 5 feet.
• When a creature within your reach attacks or forces a saving throw on a target other than you, you can, as a reaction, make an unarmed or monk weapon attack against that creature.
• Creatures provoke opportunity attacks from you even if they use the Disengage action.
• When you use your Stunning Strike on a reaction attack, you only spend the ki point if the target fails the saving throw.
