3rd-level Way of the Ninja feature

You gain access to secret arts, sometimes called ninja magic. An art requires you to spend ki points each time you use it. These effects are considered magical (or psionic if you use monk powers are psychic optional rules). When an art duplicates a spell effect, you don’t require components to use it.

You learn three arts which can choose from the options below. When you gain a new level in this class you may replace one of the arts you know with a new one.

Cricket’s Leap. You can spend 1 ki point to double your jumping distance and height for 1 minute.

Fading Presence. When you are hit by a weapon attack, you can spend 2 ki points to increase your AC against that attack by 4. You must choose to do this before the result of the attack is known.

Flash Bomb. You take an action and spend 3 ki points to blind nearby creatures. Each creature within 5 feet of you must make a Dexterity saving throw against a DC equal to 8 + your Proficiency bonus + your Wisdom modifier. On a failed save, the creature is blinded until the end of its next turn.

No Face. When you are within a crowd or in dim light or darkness, you can spend 1 ki point to take the Hide action using a bonus action. You can do this while being observed. If you aren't observed, you have advantage on ability checks to elude detection for 1 minute.

Phantom Steps. You can take an action and spend 2 ki points to manifest the water walking spell on yourself as well as making your footsteps completely silent.

Quickened Dash. When you take damage, you can use your reaction and spend 3 ki points to teleport to an unoccupied space within 5 feet of your attacker, up to a maximum of 20 feet. Weapon attacks made against you by your attacker are made with disadvantage until the start of your next turn.

Serpent’s Reed. You can spend 1 ki point to breathe under water for 1 hour using your bonus action.

Shadow Clone. You can take an action and spend 3 ki points to manifest the mirror image spell.

Thousand Faces. You can take a bonus action and spend 2 ki points to change your appearance, including clothing and armor for 1 hour or until you dismiss it using a bonus action. You can appear up to one foot taller or shorter and can appear fatter or thinner. You can't change your creature type and must have the same general shape.

You gain proficiency with sickle and chains*, blowguns, Deception, and disguise kits. Sickle and chain is introduced in Aronar’s Armory. If you aren’t using content from Aronar’s Armory, you gain proficiency with whips instead.

Additionally, sickle and chains, darts, and shortbows are treated as monk weapons for you. You also draw a weapon that has the thrown property as part of the attack you make with the weapon.

6th-level Way of the Ninja feature

Once each turn, you can add a roll of your martial arts die to your weapon damage in the following instances:

• When you make an opportunity attack.
• The first time you attack a target which hasn’t taken its first turn in combat.
• When you have advantage on the attack roll.

When you reach 17th level, you add two rolls your martial arts damage die instead.

11th-level Way of the Ninja feature

When you are attacked by a melee attack, you can take a reaction to throw one weapon with the finesse and thrown properties at your attacker. If this attack hits, your foe’s attack roll is reduced by an amount equal to the damage you deal it with the reaction.

Additionally, whenever you make an unarmed strike, you can make an attack with a one-handed melee or ranged weapon instead, provided the weapon has the finesse and thrown properties.

17th-level Way of the Ninja feature

You have achieved mastery with your secret arts. After finishing a short rest, you can use each of your Ninja Arts once without expending ki.

You also learn two more Ninja Arts.
