Saboteur

While thieves become masters of getting places they aren’t wanted and assassins deal death in droves, the saboteur litters the battlefield with dangerous traps that maim, poison, and even kill foes when they least suspect it. Their expertise also allows them to react faster when dealing with traps and by handling them on a regular basis, avoid the full brunt of effects that traps offer. Many saboteurs need to be quick on their feet and faster with their planning to trick enemies into falling for their traps.

Safety First

At 3rd level, you become a master at handling traps and avoiding them. When rolling a Saving Throw against traps, you have advantage. Additionally, you gain proficiency in Tinker’s Tools.

Trap Tinkerer

At 3rd level, you become adept at crafting mechanical traps to confound your foes. You can lay a maximum number of traps at a time equal to your Proficiency bonus and you can place more than one of the same type of trap except where noted. Laying a trap requires an action and each trap has its own reaction to set it off. A trap laid by you can be found by a creature using their action to make an Intelligence (Investigation) check against your traps Saving Throw DC.

When you first gain a level in this subclass, you gain the Deadly Needle Trap and you can select two additional trap blueprints from the list below. As you gain levels, you will be able to learn more total trap blueprints and gain access to more complex and dangerous traps. You gain an additional trap blueprint for crafting at levels 9, 13, and 17. When you gain a level in this class, you can swap out one trap blueprint you already know for a different one available at your level.

Saving Throws for all traps are equal to 8 + your Intelligence modifier + your Proficiency bonus.

At 13th level, you can lay traps as a bonus action.

Deadly Needle Trap

This trap uses a simple pressure plate and launching mechanism to fire a sharpened needle from below, striking their weak points. When a creature of your choice moves within 5 feet of this trap, it activates. When it does, make a weapon attack using your Dexterity modifier and Proficiency bonus. Upon a hit, the creature takes damage equal to a roll of your Sneak Attack damage. You can only have one of these traps out at a time, but this trap does not count against the maximum number off traps you can place. 

Binding Trap

Using numerous light but strong ropes, you set a trap intended to disable the movement of an enemy. When a creature of your choice moves within 5 feet of this trap, it activates. The creature must make a Dexterity Saving Throw or its speed becomes 0. It can make a separate Strength Saving Throw on its turn as an action to break free, which destroys the trap. Additionally, another creature can make a Strength Ability Check against the Saving Throw DC to break the trap and free the bound creature, which also destroys the trap.

At 9th level, a creature failing this save also becomes restrained. At 17th level, a creature failing this save takes 2d8 damage at the start of its turn until free as the bindings squeeze tightly enough to cut into them or crush it.

Any creature within ten feet of the trap is surrounded by black smoke, obfuscating the area and all creatures caught within the cloud are blinded while in the cloud. The black cloud of smoke will linger for one minute unless acted upon by a strong wind.

At 9th level, the trap extends to fifteen feet out and irritates the eyes, giving disadvantage on attacks made by creatures caught in the cloud for one turn after exiting. At 17th level, the trap extends to twenty feet out and the eye irritation creates disadvantage for the entire minute regardless of whether the creature is in the cloud or not. They can use their action to clear their eyes to end the effect.

Stunning Trap

Trap Master

At 17th level, you are such a master at making traps, you know how to activate them remotely. You can use your action to set off one of your traps from afar, often taking careful enemies by surprise. Your total number of traps you can have on the field at once is now your Proficiency Bonus plus your Intelligence Modifier.
