Bonus Proficiency

When you choose this archetype at 3rd level, you gain proficiency with your choice of the disguise kit or the poisoner’s kit.

Backstab

Starting at 3rd level, you are pragmatic and deadly in eliminating your foes. You have advantage on attack rolls against any creature that hasn't taken a turn in the combat yet, or when an allied creature within 5 feet of the target is directly on the other side of a creature.

Killer's Method

Starting at 9th level, you have mastered one technique of your choice for approaching a target. Select one of the following benefits:

• False Face: You gain expertise with the disguise kit, and can assume a prepared disguise with the bonus action granted by Cunning Action.
• Blade in the Dark: You gain expertise with the Stealth skill. You can attempt to hide even when you are only lightly obscured by dim light.
• Poisoner's Path: You gain expertise with the poisoner's kit. During a long rest, you can create a long lasting poison for one or more weapons for free. Until the end of your next long rest your Sneak Attack damage with that weapon becomes Poison damage and creatures struck with it must make a Constitution saving throw with a DC of 8 + your Proficiency modifier + your Dexterity modifier or become Poisoned for one minute. Creatures poisoned this way make a new save at the end of each of their turns ending the condition on success. Once a creature passes the save against this effect, it cannot suffer the Poisoned condition from it again for 24 hours.

If you gain expertise in a skill you already have expertise in, you can instead select another skill or tool you have proficiency in to gain expertise in.

Favored Approach

Starting at 13th level, you hone your skills gaining a favored approach to dealing death. Select one of the following benefits:

• Trusted Face: If you spend seven days establishing a fake identity for yourself or three hours studying another person to impersonate, you have advantage on any Charisma (Deception) check involving maintaining your disguise and identity.
• Swift Blade: When you roll initiative while hidden, you gain advantage on the roll.
• Specialized Poisons: When you create a poison, you can designate one creature type (for example, Fiends). The damage of that poison ignores resistance or immunity that creature type may have to poison.

Lethal Blows

Starting at 17th level, after you deal sneak attack damage to a creature, if the target’s remaining hit points is less than your Rogue level, the target dies. You can forgo this when intentionally making nonlethal attacks.
