Rogue: Marksman
Sharpshooters that slay their enemies from afar. A common counter to wizards, Marksmen do their best work when a foe is unaware and unprepared.
Sure Hands
Starting at 3rd level, you can use the bonus action granted by your Cunning Action to take the Use an Object action or to Take Aim.
When you Take Aim, your movement is set to zero and you gain advantage on your next ranged weapon attack. You cannot Take Aim if you’ve moved this round or if a hostile creature is within 5 feet of you.
Trade Secrets: Marksmanship
At 3rd level, you gain one of the options from the list below. You can choose an additional option at the fifth and seventh levels.
Arsenal: You gain proficiency with heavy crossbows, longbows, and firearms.
Sharp Eyes: You gain proficiency and expertise in one of the following: Perception or Investigation.
Longshot: You do not suffer disadvantage when using a weapon at its long range.
Make Space: When you take the Dash action, you also gain the benefits of the Disengage action.
Pinning Strike: When you deal damage with a ranged sneak attack, the target’s movement is halved until the end of their next turn.
Sharpshooting
Starting at 9th level, you learn new techniques for ranged weapons.
Unerring Shot: You can use your action to make a ranged weapon attack that ignores the benefits of half or three-quarters cover. Creatures without any cover take an additional 1d6 damage from this attack.
Volley: You can use your action to make a ranged attack against any number of creatures within 10 feet of a point you can see within your weapon’s range. You must have ammunition for each target, as normal, and you make a separate attack roll for each target.
Use Mystic Device
At 13th level, the number of items you can attune to increases by one.
Thief’s Reflexes
When you reach 17th level, you have become adept at laying ambushes and quickly escaping danger. You can take two turns during the first round of any combat. You take your first turn at your normal initiative and your second turn at your initiative minus 10. You can’t use this feature when you are surprised.
