Gift of the Machine God. As a creature of technology, The Doctor gains many damage and condition resistances and immunities, but he is also susceptible to lightning attacks.   Combat Hardened. The surgeon robots were sometimes used in combat, and field medics were built with survival in mind. He has an advanced robotic frame which provides a measure of protection against attacks. The robot surgeon has a damage threshold of 10. It reduces all damage by ten.   Force Field. A surgeon robot is sheathed in a thin layer of shimmering energy that grants it 75 bonus hit points. All damage dealt to a surgeon robot with an active force field is deducted from these hit points first. The surgeon robot is immune to critical hits as long as the force field is active. A surgeon robot’s force field recharges to full strength at the start of its turn, but once these bonus hit points are reduced to 0, the force field shuts down and doesn’t reactivate for 24 hours.   Master Surgeon. Programmed to execute advanced medical procedures, a surgeon robot can perform surgeries and other procedures that heal humanoid creatures of all manner of maladies. A surgeon robot can heal wounds, set broken bones, cure diseases, treat burns, remove poison, and even install cybertech items. These procedures take varying amounts of time for the surgical robot to complete and require different Medicine check DCs. The DCs for these surgical procedures increase by 10 when they’re performed on a non-humanoid creature. These procedures leave the patient with the exhausted condition. If the surgeon robot fails any of its Medicine checks, the surgery fails, and the patient takes 1d6 levels of exhaustion. The procedures a surgeon robot can perform are as follows:  

  • Cure Blindness/Deafness (DC 15): The patient’s sight or hearing is restored. Required Time: 30 minutes.
  • Install Cybertech (DC = 5 + the cybertech install DC): Cybernetic equipment is installed safely. Required Time: 20 minutes per point of implantation of the cybertech being installed.
  • Minor Surgery (DC 10): The patient is healed of 1d8+1 points of damage. Required Time: 5 minutes.
  • Moderate Surgery (DC 15): The patient is healed of 2d8+3 points of damage and 1d4+1 levels of exhaustion or similar affect like hit point drain. Required Time: 10 minutes.
  • Major Surgery (DC 25): The patient is healed of 3d8+5 points of damage and is cured of blindness and deafness. Required Time: 15 minutes.
  • Critical Surgery (DC 30): The patient is healed of 4d8+7 points of damage and completely heals some other condition (exhaustion, energy drain etc.). Required Time: 30 minutes.
  • Treat Toxin (DC = 10 + the save DC of disease or poison): One disease or poison currently afflicting the patient is removed. Required Time: 10 minutes.
Sneak Attack (1/Turn). Due to its encyclopedic knowledge of anatomy, The Doctor deals an extra 13 ( 4d6 ) damage when he hits a target with a weapon attack and has advantage on the attack roll or when the target is within 5 feet of an ally of The Doctor that isn’t incapacitated, and The Doctor doesn’t have disadvantage on the attack roll.   Specialised Programming. Medicine is always a class skill for surgeon robots, and it gains advantage Medicine checks.   Superior Optics. Surgeon robots see invisible creatures or objects as if they were visible.   Syringe. When a surgeon robot successfully attacks its syringe, it can inject the target with pharmaceuticals. The robot contains nanites that fabricate the pharmaceuticals stored within its body. Up to 10 doses of these pharmaceuticals can be administered per day. The surgeon robot can choose to affect its target with:
  • anaesthetic, the target must make a CON saving throw or become paralysed for 1 hour and completely numb to pain. The target can repeat the saving throw, if it so chooses, at the end of each minute.
  • cardioamp, acts as revivify, can also cause a heart attack in living creatures – CON saving throw or suffer 1d6-1 levels of exhaustion. Even on a success, the target gains the sickened state (as poison)),
  • cureall treat as a lesser restoration spell,
  • hemochem (grade III) (Regeneration 3),
  • torpinal (as suggestion, DC 17 Wisdom), or
  • zortaphen (CON or have disadvantage on all d20 checks).


Multiattack. The surgeon doctor can make six attacks from the options below.   Precision Scalpel. Melee Weapon Attack: +10 to hit ( 1d20+10 ), reach 5 ft., one target. Hit: 16 (3d6 + 7) ( 3d6+7 ) piercing damage.   Clamping Claws. Melee Weapon Attack: +10 to hit ( 1d20+10 ), reach 5 ft., one target. Hit: 12 (3d4 + 6) ( 3d4+6 ) slashing damage plus the target is grappled (Escape DC 18). At the start of The Doctor’s turn, if it so chooses, the creature automatically takes 12 (3d4 + 6) bludgeoning damage. The Doctor may only grapple two opponents and losses its claw attack while grappling.   Syringe. Melee Weapon Attack: +12 to hit ( 1d20+12 ), reach 10ft., one target. Hit: 16 (3d6 + 7) ( 3d6+7 ) piercing damage plus pharmaceutical effect.   Integrated Surgical Laser. Ranged Weapon Attack: +12 to hit ( 1d20+12 ), range 120ft., one target. Hit: 16 (3d6 + 7) ( 3d6+7 ) radiant damage.

This robot has the general appearance of a skeletal praying mantis fashioned entirely from gleaming metal. An array of limbs fitted with laser scalpels, syringes, and other surgical devices spring from its body.
