Slasher

Specializing in jumping out at foes from the darkness, Slashers strike pure fear within the hearts of their prey.

Silent Hunter

When you first choose this archetype at 3rd level, your footsteps and breathing become completely silent. Additionally, when in dim light and darkness, you gain an additional ten feet of movement speed.

Brutality

Also at 3rd level, when you kill a creature using your Sneak Attack, every creature within twenty feet of you must make a Constitution saving throw (DC equals your Intelligence score), all who fail become frightened of you for one minute. At the beginning of every frightened creature’s turn, they can repeat the saving throw.

At 13th level, this effect happens regardless if you kill a creature with your Sneak Attack or not and every creature within thirty feet must make the saving throw.

Unflinching Hunter

At 9th level, when you do the Dash action on your turn, you become resistant to bludgeon, piercing, and slashing damage until the beginning of your next turn.

Ghastly Speed

At 13th level, when in complete darkness, you can use your action teleport to another area in dim light or darkness within one-hundred feet of you.

You can use this feature a number of times per day a number of times equal to your Dexterity modifier.

Slasher's Stride

At 17th level, if you take the Dash action on your turn and stop within five feet of another creature, you may use your bonus action to make a Sneak Attack against that creature.
