Surgeon

When an adventurer is maimed by a monster or a soldier is wounded in battle, and the luxury of magical healing is not an option, Surgeons step up to fill the void. Using their intimate understanding of anatomy and biology, Surgeons can analyze any ailment, and, when pressed, they can turn their medical knowledge onto their foes, crippling them with precise cuts.

Maim. You force the target to make a Dexterity saving throw (DC equals 8 + your proficiency bonus + your Intelligence Modifier). On a failed save, the target is blinded, deafened, or cannot speak (your choice) until the end of your next turn.

Cultivated Immunity

The time you have spent around various infectious diseases and toxins has improved your immune system. Beginning at 9th level, when you gain resistance to necrotic and poison damage. Additionally, you have advantage on saving throws to resist the effects of poisons, diseases, and any other toxins.

Improved Surgical Strike

You have learned much about the anatomy of the creatures of the multiverse. Starting at 13th level, your attack rolls against all creatures except for constructs, oozes, and plants score a critical hit on a roll of 19 or 20 on the d20.

Moreover, when you inflict one of the conditions from your Surgical Strike feature, you can still deal your Sneak Attack damage to the target in addition to the additional effect.

Expert Surgeon

As an action, you can touch a creature and inflict the effects of either the contagion or regenerate spell, using your Intelligence in place of a spellcasting modifier. You can do this without any verbal, somatic or material components. Once you recreate either spell you must finish a short or long rest before you can do so again.
