Shortsword. Melee Weapon Attack: +6 to hit, reach 5 ft., one target. Hit: 5 (1d6 + 4) piercing damage.

Steady Aim (Optional)

At 3rd level, as a bonus action, you give yourself advantage on your next attack roll on the current turn. You can use this bonus action only if you haven't moved during this turn, and after you use the bonus action, your speed is 0 until the end of the current turn.

Eye for Detail

Starting at 3rd level, you can use a bonus action to make a Wisdom (Perception) check to spot a hidden creature or object or to make an Intelligence (Investigation) check to uncover or decipher clues.

Insightful Fighting

At 3rd level, you gain the ability to decipher an opponent’s tactics and develop a counter to them. As a bonus action, you make a Wisdom (Insight) check against a creature you can see that isn’t incapacitated, contested by the target’s Charisma (Deception) check. If you succeed, you can use your Sneak Attack against that target even if you don't have advantage on the attack roll, but not if you have disadvantage on it.

This benefit lasts for 1 minute or until you successfully use this feature against a different target.

Uncanny Dodge

Starting at 5th level, when an attacker that you can see hits you with an attack, you can use your reaction to halve the attack's damage against you.
