Operation

This is my best attempt to make Trafalgar Law from One Piece. This subclass specializes in manipulating an area and the creatures within a dome.

Room

At 3rd level you can conjure a blue translucent sphere centered on you as a bonus action. It's radius is a number of feet equal to ten times your rogue level, it spreads around corners and the sphere doesn’t move. This sphere lasts for 1 minute, until you dismiss it as a bonus action, drop to 0 Hit points or are incapacitated. You can make a number of Rooms equal to your Proficiency bonus and you regain all expended uses on a long rest. You can’t have more than 1 Room up at a time, if you use Room again the previous one dismisses itself. You also gain these benefits:

• While in the Room you can telekinetically manipulate an object, open an unlocked door or container, stow or retrieve an item from an open container, or pour the contents out of a vial. You can move any object you are manipulating up to 30 feet as a bonus action. You can't attack, activate magic items, carry more than 10 pounds within the Room using this feature and you can't use this feature on objects outside of the Room. If anything you are manipulating with this feature moves out of the Room, you lose control over it.
• Whenever you make a Wisdom (Medicine) or a Wisdom (Perception) check while you are in your Room, treat a roll of 7 or lower on the d20 as an 8.
• Whenever you take the Attack action inside your Room and intend to use Sneak Attack. The range for that Attack increases by 5 feet. The extra 5 feet attack range you gain from this feature can move 5 feet through the space of anything that isn't immune to piercing damage.

Injection Shot

At 3rd level your knowledge of Anatomy and Medicine grant you the following benefits:

• If you lack proficiency with Wisdom (Medicine) or Wisdom (Perception) you gain them. Otherwise you ignore this feature.
• You can add your Intelligence or Wisdom modifier (You choose) to the damage of all your sneak attacks.

Mes

At 9th level when you hit a creature with your sneak attack while inside of your Room you can force that creature to make a Dexterity saving throw (DC equal to 8 + your proficiency bonus + your Dexterity modifier). On a failed save that target's heart is expelled out of their body, encased in a glass-like cube and appears in one of your empty hands, if neither of your hands are empty it appears on the nearest unoccupied space near you. This attack leaves a cube-shaped hole on the opponent's body where the heart was. If they don’t have a heart in their body then obviously this doesn’t work. (Note that removing their heart in this way does not affect or kill them like removing a heart normally would, the heart is still beating, they are fine.)

The heart's AC is 5, and its Hit Points are tied to their owners, meaning that if the owner or heart takes damage they both share that damage. The heart is considered an object. The heart reappears in the owner's body at the end of your next long rest, if it takes damage 3 separate times, if a creature uses the Use An Object action to place the heart back or if the owner is killed.

You can use this ability an equal amount of times to your Proficiency bonus. You regain all uses after a long rest.

Shambles

At 13th level while inside your Room, as an action you can choose two creatures, loose objects or loose constructs within your Room (including you). The targets then swap places with each other. If one of the targets is unwilling then they must make a Charisma saving throw (DC 8 + Proficiency Bonus + Dexterity Modifier) to resist the effects. You can do this a number of times equal to your Proficiency Bonus and regain all expended uses after a long rest.

Shock Wille

At 17th level you have honed your abilities to their peak. You gain these benefits:

• Whenever you take the Attack action inside your Room and intend to use Sneak Attack. the targets AC changes to 10 + their Dexterity modifier for that attack roll and all of the attacks damage bypasses any resistances and immunities.
• Room no longer has a weight limit on what you can manipulate with it and it can also affect constructs, as long as the object or construct is loose. In addition the objects and constructs you manipulate can be moved up to 60 feet as a bonus action instead of 30.
