You can take the Dash, Disengage, or Hide action as a bonus action on each of your turns.

You can use a bonus action on your turn to make a Dexterity check, use thieves' tools to disarm a trap or open a lock, or take the Use an Object action.

When you are not incapacitated, you can use your reaction to halve the damage from an attack that hits you.

You have a knack for reading people and exploiting openings in combat and social situations. You can choose two of your skill or tool proficiencies to double your proficiency bonus, and you later gain two more. For Eris, these are reflected in her exceptional mastery of stealth, sleight of hand, thieves' tools, and perception.

You know how to strike subtly and exploit a foe's distraction. Once per turn, you deal an extra 6d6 damage when you hit with a finesse or ranged weapon attack if you have advantage on the attack roll or if another enemy of the target is within 5 feet of it and you do not have disadvantage.

You know the secret signs and phrases used by thieves and criminals. You can convey hidden messages to other creatures familiar with the code.

Your chosen rogue archetype grants you a foot in the shadows of organized crime and a taste for improvised trickery. Your hands are quick, your climbing is better than most, and your instincts for burglary are exceptionally sharp.

You gain a climbing speed equal to your walking speed, and you can make running jumps farther than normal. You move through the vertical world as if it were another alleyway.

You have learned to turn small improvements into major advantages. You gain an Ability Score Improvement at this level and again at 8th level.

Your talent for slipping past danger becomes near supernatural. When you are subjected to an effect that allows you to make a Dexterity saving throw to take only half damage, you instead take no damage on a success and only half damage on a failure.

At 9th level, your movement and balance become notoriously difficult to pin down. You can move through crowds, ledges, and slick surfaces with uncanny confidence, making it hard for pursuers to keep up with you.

You can add your proficiency bonus to any ability check you make that uses a skill proficiency you lack. Also, whenever you make an ability check that lets you add your proficiency bonus, you can treat a d20 roll of 9 or lower as a 10. Eris becomes frighteningly reliable under pressure, especially when the odds are bad.

Eris knows the hidden routes, warning signs, and coded customs of the underworld. She can usually find a place to lay low, a fence willing to talk, or someone who owes the right people favors. She can also draw on contacts who recognize her old trade, even if they do not trust her.
