Shinobi

The Shinobi are covert agents and mercenaries, whose functions included espionage, deception and assassination. Deemed dishonourable by the Samurai, the Shinobi are often employed directly by the nobles that need them, instead of by the generals of their armies. They are often a topic of great mystique and imagination for the common folk, who tell the wildest of stories about the Shinobi.

From The Shadows

When you adopt this archetype at 3rd level, you learn to strike from the shadows to surprise your foes.

When you are in an area of dim light or darkness, you can always use your sneak attack on opponents without darkvision, as long as you don't have disadvantage on your attack.

Shinobi Tools

When you adopt this archetype at 3rd level, you learn to use a variety of tools specific to the Shinobi.

• Climbing Claws: These claws can be used to climb up steep surfaces. While wearing them, you gain a climbing speed equal to your walking speed.
• Smoke Bombs: These small pellets can be thrown on the ground as a bonus action to create an area of smoke around you. When you use them, the area around you becomes heavily obscured. The smoke dissipates at the start of your next turn.
• Rope Arrows: These arrows have ropes attached to them and can be used much like grappling hooks.

Silent Body

At 9th level, you have learned to silence your body completely.

You are permanently hidden to any creature that relies on any senses other than sight or smell to see you.

Additionally, you are also permanently hidden to creatures without darkvision if you are in darkness.

Shadow Ambush

At 13th level, you have mastered the art of the ambush.

You have advantage on initiative, and if you attack a creature that hasn't yet acted, your attack becomes an automatic critical hit.

Alternatively, you can choose to unleash a flurry of attacks quickly. You can attack a number of creatures equal to your Sneak Attack dice in your weapon's range that haven't yet acted. You cannot use multiple Sneak Attack dice on one target.

Heightened Senses

At 17th level, you have learned to optimally tune your senses to superhuman levels.

Creatures can no longer hide from you so long as you at least have one of your senses available to you.
