Techno-Trickster

To defeat the powers that be there are mad scientists that seek to push technology to its limits, focusing their efforts on explosives, traps, and outsmarting their opponents. You have a penchant for incendiary devices and dangerous machines, bending your mind to perfecting their use in combat.

Overcharged Shot

Starting at 1st level, when you have advantage on a spell attack using your technological weapon, you may choose to lose advantage but deal an extra 1d4 damage per 2 mad scientist levels (minimum 1d4). Once you have used this feature a number of times equal to your proficiency bonus, you cannot do so again until after you finish a long rest.

Bomb Thrower

Beginning at 5th level, you gain access to the grenadier feature except that you are only able to throw 2 grenades as an attack action. When you reach 18th level, you may throw 5 grenades as an attack action.

Deadly Terrain

At 11th level, you can spend a bonus action throwing down a saw-toothed steel ring that snaps shut when a creature steps on a pressure plate in the center. The trap blends in with its surroundings, and a creature requires a Perception check against your spell save DC to pick it out from the 5-foot square it rests in. A creature that steps in the same square as the trap must succeed on a Dexterity saving throw against your spell save DC or take 1d4 piercing damage per point of proficiency bonus you possess and gain the restrained condition. A creature can use its action to make a Strength check against your spell save DC, freeing itself or another creature within its reach on a success. Each failed check deals 1d4 piercing damage per point of proficiency bonus you possess to the trapped creature. You may have a number of these traps on your person equal to your proficiency bonus. Uses of this feature recharges on a long rest.

Hide Out of Place

At 17th level, you become a master of being where eyes are not looking. You are able to hide using Deception instead of Stealth and while doing so may hide in plain sight (without any cover or obscurement).

Scientific Gadgets

If a scientific gadget has prerequisites, you must meet them to learn it. You can learn the gadget at the same time that you meet its prerequisites. A level prerequisite refers to your level in this class. Some warlock eldritch invocations are suitable as scientific gadgets along with those listed here.
