Why Assassin?

As an Assassin Rogue, your main job is to act as a high-damage "Striker," slipping past enemy lines to take down high-priority targets before they can react. Your high Dexterity powers both your weapon attacks and your Stealth skill. This pairs beautifully with the Halfling's Naturally Stealthy trait, which lets you hide behind companions or larger creatures. By staying hidden, you can easily trigger your Assassinate feature, which gives you automatic critical hits against surprised foes.

Halflings also bring amazing survival tools to the table. The Luck trait lets you reroll any natural 1s on your d20, ensuring an untimely fumble doesn't ruin your perfect ambush. Meanwhile, Halfling Nimbleness allows you to slip right through the spaces of larger enemies, letting you reposition effortlessly to land a devastating Sneak Attack.

Assassin Features

Assassinate

Level 3

You have advantage on attack rolls against any creature that hasn't taken a turn in combat yet. In addition, any hit you score against a surprised creature is a critical hit.

Assassin's Tools

Level 3

You gain proficiency with the disguise kit and the poisoner's kit.

Infiltration Expertise

Level 9

You can unfailingly create false identities for yourself. You must spend seven days and 25 gp to establish the history, profession, and affiliations for an identity. You can't establish an identity that belongs to someone else. Thereafter, if you adopt the new identity as a disguise, other creatures believe you to be that person until given an obvious reason not to.

Envenom Weapons

Level 13

You can apply a special poison to your weapons as a bonus action. The next time you hit a creature with a weapon attack within the next minute, the target takes additional poison damage equal to your Sneak Attack damage and must make a Constitution saving throw (DC 8 + your Dexterity modifier + your proficiency bonus) or be poisoned for 1 minute.

Death Strike

Level 17

When you hit a surprised creature, it must make a Constitution saving throw (DC 8 + your Dexterity modifier + your proficiency bonus). On a failed save, the damage of the attack is doubled.
