As a rogue, you gain the following class features.

Hit Points

Hit Dice: 1d8 per rogue level
Hit Points at 1st Level: 8 + your Constitution modifier
Hit Points at Higher Levels: 1d8 (or 5) + your Constitution modifier per rogue level after 1st

Proficiencies

Armor: Light armor
Weapons: Simple weapons, martial weapons with the Finesse property
Tools: Thieves' tools
Saving Throws: Dexterity, Intelligence
Skills: Choose four from Acrobatics, Athletics, Deception, Insight, Intimidation, Investigation, Perception, Performance, Persuasion, Sleight of Hand, and Stealth

Equipment

You start with the following equipment, in addition to the equipment granted by your background:

• (a) a rapier or (b) a shortsword
• (a) a shortbow and quiver of 20 arrows or (b) a shortsword
• (a) a burglar's pack, (b) dungeoneer's pack, or (c) an explorer's pack
• Leather armor, two daggers, and thieves' tools

Expertise

At 1st level, choose two of your skill proficiencies, or one of your skill proficiencies and your proficiency with thieves' tools. Your proficiency bonus is doubled for any ability check you make that uses either of the chosen proficiencies.

At 6th level, you can choose two more of your proficiencies (in skills or with thieves' tools) to gain this benefit.

Sneak Attack

Beginning at 1st level, you know how to strike subtly and exploit a foe's distraction. Once per round, you can deal an extra 1d6 damage to one creature you hit with an attack if you have advantage on the attack roll. The attack must use a finesse or a ranged weapon.

You don't need advantage on the attack roll if another enemy of the target is within 5 feet of it, that enemy isn't incapacitated, and you don't have disadvantage on the attack roll.

The amount of the extra damage increases as you gain levels in this class, as shown in the Sneak Attack column of the Rogue table.

Thieves' Cant

During your rogue training you learned thieves' cant, a secret mix of dialect, jargon, and code that allows you to hide messages in seemingly normal conversation. Only another creature that knows thieves' cant understands such messages. It takes four times longer to convey such a message than it does to speak the same idea plainly.

In addition, you understand a set of secret signs and symbols used to convey short, simple messages, such as whether an area is dangerous or the territory of a thieves' guild, whether loot is nearby, or whether the people in an area are easy marks or will provide a safe house for thieves on the run.

Cunning Action

Starting at 2nd level, your quick thinking and agility allow you to move and act quickly. You can take a bonus action on each of your turns in combat. This action can be used only to take the Dash, Disengage, or Hide action.

Roguish Archetype

At 3rd level, you choose an archetype that you emulate in the exercise of your rogue abilities. Your archetype choice grants you features at 3rd level and then again at 9th, 13th, and 17th level.

Surprise Tumble

At 3rd level, as a bonus action you can attempt to swiftly reposition yourself behind an enemy within 5 feet of you. Make a Dexterity (Acrobatics, Sleight of Hand, or Stealth) check contested by the target's Dexterity (Acrobatics) check.

On a success, you move through the target's space to an unoccupied space of your choice within 5 feet of the target. You don't provoke opportunity attacks against the target for the rest of your turn, and you give yourself advantage on your next attack roll against the target before the start of their next turn.

Steady Aim (Optional)

This 3rd-level feature replaces the Surprise Tumble feature. You gain no benefit from the replaced feature and don't qualify for anything in the game that requires it.

As a bonus action, you give yourself advantage on your next ranged 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.

Ability Score Improvement

When you reach 4th level, and again at 8th, 10th, 12th, 16th, and 19th level, you can increase one ability score of your choice by 2, or you can increase two ability scores of your choice by 1. As normal, you can't increase an ability score above 20 using this feature.

Cunning Strike

Starting at 5th level, you've developed cunning ways to use your Sneak Attack. When you deal Sneak Attack damage, you can add one of the following Cunning Strike effects. Each effect has a die cost, which is the number of Sneak Attack dice you must forgo to add the effect. You remove the die before rolling, and the effect occurs immediately after the attack's damage is dealt. For example, if you add the Poison effect, remove 1d6 from the Sneak Attack's damage before rolling.

If a Cunning Strike requires a saving throw, the DC equals 8 plus your Dexterity modifier and Proficiency Bonus.

Poison (Cost: 2d6). You add a toxin to your strike, forcing the target to make a Constitution saving throw. On a failed save, the target has the Poisoned condition for 1 minute. At the end of each of its turns, the poisoned target repeats the save, ending the effect on a success.

To use this effect, you must have proficiency with a Poisoner's Kit and have one on your person.

Trip (Cost: 1d6). If the target is Large or smaller, it must succeed on a Dexterity saving throw or have the Prone condition.

Withdraw (Cost: 1d6). Immediately after the attack, you move up to half your speed without provoking Opportunity Attacks.

When you reach 11th level, you can use up to two Cunning Strike effects when you deal Sneak Attack damage, paying the die cost for each effect.

Uncanny Dodge

Also 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.

Alternatively, if the attacker is within 5 feet of you, you can instead use your reaction to attempt a counter. Make a Dexterity (Acrobatics, Sleight of Hand, or Stealth) check contested by the target's Dexterity (Acrobatics) check.

On a success, you may choose to move the target through your space to an unoccupied space of your choice within 5 feet of you. You take half damage and you give yourself advantage on your next attack roll against the target before the start of their next turn. On a failure, you take normal damage.

Evasion

Beginning at 7th level, you can nimbly dodge out of the way of certain area effects, such as a red dragon's fiery breath or an Ice Storm spell. 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 if you succeed on the saving throw, and only half damage if you fail.

Reliable Talent

By 11th level, you have refined your chosen skills until they approach perfection. 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.

Devious Strikes

Starting at 14th level, you've practiced new ways to use your Sneak Attack deviously. The following effects are now among your Cunning Strike options.

Daze (Cost: 2d6). The target must succeed on a Constitution saving throw, or on its next turn, it can do only one of the following: move or take an action or a Bonus Action.

Knock Out (Cost: 6d6). The target must succeed on a Constitution saving throw, or it has the Unconscious condition for 1 minute or until it takes any damage. The Unconscious target repeats the save at the end of its turns, ending the effect on itself on a success.

Obscure (Cost: 3d6). The target must succeed on a Dexterity saving throw, or it has the Blinded condition until the end of its next turn.

Blindsense

Additionally at 14th level, if you are able to hear, you are aware of the location of any hidden or invisible creature within 10 feet of you.

Slippery Mind

By 15th level, you have acquired greater mental strength. You gain proficiency in Wisdom saving throws.

Elusive

Beginning at 18th level, you are so evasive that attackers rarely gain the upper hand against you. No attack roll has advantage against you while you aren't incapacitated.

Stroke of Luck

At 20th level, you have an uncanny knack for succeeding when you need to. If your attack misses a target within range, you can turn the miss into a hit. Alternatively, if you fail an ability check, you can treat the d20 roll as a 20.

Once you use this feature, you can't use it again until you finish a short or long rest.
