Rogue: Surgeon

Original Source: Original Homebrew

Acupuncture

3rd-level Surgeon feature
At 3rd level, you gain the ability to decipher an opponent’s weak points and target them. As a bonus action, you make a Wisdom or Intelligence (Medicine) check against a creature you can see that isn’t incapacitated, with a DC equal to the target’s Constitution score. If you succeed, you can use your Sneak Attack against that target even if you don't have advantage on the attack roll, but not if you have disadvantage on it.

This benefit lasts for 1 minute or until you successfully use this feature against a different target.

Doctor

3rd-level Surgeon feature
You are a medical professional, whether or not you have an official certification. You are proficient in Medicine. Additionally, whenever you make a Wisdom or Intelligence (Medicine) check, treat a roll of 7 or lower on the d20 as an 8.

Cunning Action: Medicate

3rd-level Surgeon feature
You can use a bonus action to take the Use an Object action, or to administer a potion, antidote, or other beneficial consumable item to yourself or a creature within your reach. You may draw this item as a part of the same action.

Operation

9th-level Surgeon feature
You know many medical procedures to help treat the most serious injuries of your comrades. During a short or long rest, you can operate on a creature of your choice. Make an Intelligence or Wisdom (Medicine) check and roll your Sneak Attack dice. The creature recovers that many hit points on a success, or half as much on a failure.

The base DC of this check is 10. Consult the table below to determine modifiers which can increase the difficulty of the check. If you exceed the DC by 5 or more, you may also end one condition causing a creature to be Poisoned or Diseased, the effects of one Lingering Injury, or an effect causing its hit points or statistics to be reduced.

Surgical Precision

13th-level Surgeon feature
Starting at 13th level, your attacks with light weapons score a critical hit on a roll of 18-20.

Pressure Points

17th-level Surgeon feature
You know how to cause your targets to seize up. While your Acupuncture feature applies to a creature, when you hit that creature with your Sneak Attack with a melee weapon, you can strike that creature at their weakest point. The creature must make a Constitution saving throw (DC = 8 + your Dexterity modifier + your proficiency bonus) or be paralyzed for 1 minute. The creature can repeat this saving throw at the end of its turn, ending the effect on a success.

A creature who succeeds on this saving throw or ends the effect is immune to this ability for 1 hour, or until you inflict a critical hit on them.
