Thief (Remastered)

You hone your skills in the larcenous arts. Burglars, bandits, cutpurses, and other criminals typically follow this archetype, but so do rogues who prefer to think of themselves as professional treasure seekers, explorers, delvers, and investigators. In addition to improving your agility and stealth, you learn skills useful for delving into ancient ruins, reading unfamiliar languages, and using magic items you normally couldn’t employ.

This subclass build combines some abilities of the official 5th edition Thief subclass and the Kobold Press Tome of Heroes Cat Burglar subclass. If any formatting fails to function, leave a comment for me! Thanks, gang.

Fast Hands

Starting at 3rd level, you can use the bonus action granted by your Cunning Action to make a Dexterity (Sleight of Hand) check, use your thieves’ tools to disarm a trap or open a lock, or take the [Tooltip Not Found] action.

Up, Over, and In

When you choose this archetype at 3rd level, you gain a climbing speed equal to your walking speed. If you already have a climbing speed equal to or greater than your walking speed, it increases by 10ft. In addition, when you are falling, you can use your reaction to soften the fall. You reduce the falling damage you take by an amount equal to your proficiency bonus + your rogue level. You don't land prone, unless the damage you take from the fall would reduce you to less than half your hit point maximum.

Supreme Sneak

Starting at 9th level, you have advantage on a Dexterity (Stealth) check if you move no more than half your speed on the same turn.

Breaking and Entering

At 13th level, when you make an attack against a door, gate, window, shutters, bars, or similar object or structure that is blocking or barring an egress, you have advantage on the attack roll, and you can add your sneak attack damage on a hit. You can choose for this damage to be audible out to a range of 100 feet or to be audible only within 5 feet of the point where you hit the object or structure. Similarly, you can choose for this damage to appear more or less impactful than it actually is, such as neatly carving a hole for you to squeeze through a wall or window or bursting a door off its hinges.
Your expertise at deftly dismantling crafted works extends to constructs and undead. You don't need advantage on the attack roll to use your sneak attack feature against constructs or undead. As normal, you can't use sneak attack if you have disadvantage on the attack roll.

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.
