The Surgeon of War

Fighters who wield both the scalpel and the sword, mastering the battlefield with surgical precision.

Those who consume the mythical Surgeon’s Surgery Fruit awaken to an unparalleled mastery over space and anatomy, transforming them into both a field medic and a relentless warrior. With their unique power, they manifest a domain known as the Room, a supernatural space where they dictate the flow of battle with surgical finesse. Within this sphere of control, they can amputate limbs without bloodshed, manipulate enemies like pieces on a chessboard, and perform life-saving operations amid combat.

A Surgeon of War is a paradox—both a healer and a destroyer. Their blade is not just a weapon but a scalpel, carving through foes with terrifying accuracy while preserving the lives of allies with unparalleled medical expertise. Whether dismantling enemies with a flick of their blade or reassembling wounded comrades with supernatural precision, they are the ultimate battlefield tacticians. To face a Surgeon of War is to step into their operating theater—where they decide who lives, who dies, and who walks away in one piece.

Spacial Control: Room

Level 3 Feature

You gain the ability to manifest the Room, a supernatural sphere of control. This ability lasts for 1 minute and requires concentration for up to 5 minutes to freely summon another Room for the duration of the concentration or until concentration is broken or voluntarily end the concentration to manifest the Room. It covers a radius of 20 feet centered on you.

• Room: This ability manifests as part of your action before you take your attack action. There can only be one Room; if you create a new one, the old one expires.
  • Room Concentration: Once you spend one of charge creating a Room you can then use a Bonus action instead of being part of the action to summon another Room after the first one expires without spending another use, and taking damage or extending a concentration needs a (DC 10) Wisdom save to maintain the Room per turn. You can only do this if you don't have Room charges left.
  • You can manifest the Room outside the battle with our spending charges and with no concentration, and then the room disappears after resolving its purpose.

Room Expansion: When you take the Attack action, you may create, move the room up to 20ft or make the Room move with you.

• At level 10, the Room size increases to 30 feet, and you can make the room silent, which means no form of sound will be coming in or out of the room, no spells can be cast with verbal components, and telepathy is also silent.
• At level 15, the Room size is now 40 feet, and enemies inside the room are now silenced.
• At level 18, the room size is 50+ feet.

You may use this feature several times equal to your Proficiency Bonus per long rest.

Room Abilities

1. Shambles: As a bonus action, you can teleport yourself, an Item/Object or an Ally/Enemy within the Room up to swap places.

   At level 7, you create a Room (if there are none), and you and up to 4 creatures within the room to swap places with any object or creature within the room vicinity.

   • You can teleport inside a locked room, provided there are things or creatures on the other side to swap to.
   • You can teleport anything within the room to your hand, provided you are holding something to swap it to.
   • If you use Mess, you can teleport that organ to you or swap it with another person's organ, giving them the effect Rejecting Organ, posing a disadvantage on everything they do if the class of organ that was swapped doesn't match their class. (ex. Fighter's heart to a Wizard and vice versa)
     • The Rejecting Organ effect is permanent unless their proper organ returns to their body.
2. Mess: (At Level 7) As an action, you unleash your most terrifying technique, warping the anatomy of every creature within the Room with surgical precision. Every creature of your choice inside the Room must make a DC 14 Constitution saving throw.

   • On a Failure: You extract one of the creature’s major body parts—such as their heart—without causing immediate death. The organ continues to function as if still inside their body, sustaining them. However, the removal causes no pain but leaves a box shaped hole on their body, imposing disadvantage on all attack rolls, ability checks, and concentration checks (Rejecting Organ) until the organ is returned.

     • Mess: Shambles - Instead of taking their heart you can instead pull their hearts out then use shambles to swap them randomly with everyone else who's heart was pulled out. They will suffer disadvantage on all attack rolls, ability checks and other actions (Rejecting Organ) because they are making these action not in their body. They will now use  the HP, AC, and passive Strength and Weakness of the body that they are in but they wont be able to use active abilities like breath weapon and other similar species abilities the body they possess.

   • On a Success: Their hearts tills pops out but lands on their hand making them able to return it quickly on their turn as a Bonus Action.

     • Mess: Shambles - Their heart will still swapped with the others but they will suffer no Disadvantages and able to utilize everything the body they now possess.

   Any damage or destruction to the extracted organ inflicts severe pain, causing the creature to take double the damage as unavoidable Physical Damage when the damage occurs until the organ is returned or magically regenerated.

   You can freely manipulate the extracted organ within the Room, keeping it suspended in the air, moving it, or teleporting it to your hand, holding it hostage even if the room is gone. The organ will be considered as a Special Item that can be stashed in the inventory.

   This ability can be used once per Room activation.

3. Phantom Strikes: Any melee attacks you make inside the Room always hit all targeted creatures inside the Room, regardless of range and AC.

4. Tact: You can interact with objects inside the Room telekinetically, moving them up to 15 feet in any direction.

   •  A range attack made against you or an ally that is inside a Room will have a disadvantage.

   • Slamming objects to creatures and vise versa will follow fall damage rules.

The operation is painless, and you can easily remove any body parts and let them sit outside the body for hours while it still does its job as if they're still attached to the body. You need to roll for the Medicine Check to see how well you perform the surgery. 

  • Surgical Operation: You can perform this to attempt to remove unwanted things in a body that have long rested, potions of greater restoration, and other curses and effects, removing things that can't be removed or attaching body parts (like extra limbs or a transplant) without complications and pain.
