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.

Anatomical Studies

You have spent years studying the science of medicine in order to improve your surgical skills. You gain proficiency in both Medicine and Nature, and whenever you make a Wisdom (Medicine) check you gain a bonus to your roll equal to your Intelligence modifier (minimum of +1).

Finally, you can use the bonus action granted by your Cunning Action to use a Healer's Kit, make a Wisdom (Medicine) check, or to administer a potion.

Surgeon Exploits

You learn certain Exploits at the Rogue levels noted in the table below. These don't count against your total number of Exploits Known and can't be switched upon gaining a level.

Surgical Skills

You weaponize your knowledge of anatomy to cripple your foes in combat. Your weapon attack rolls against humanoids, beasts, giants, monstrosities, and undead creatures score a critical hit on a roll of 19 or 20 on the d20.

Moreover, you can use each Surgeon Exploit you know once per long rest without expending an Exploit Die.

Cultivated Immunity

Your time as a Surgeon has improved your immune system. Whenever you take acid, necrotic, or poison damage, you reduce the damage by an amount equal to one roll of your Exploit Die + your Intelligence modifier (minimum of 1).

Additionally, you have advantage on saving throws to resist the effects of poisons, diseases, and any other toxins.

Surgical Strikes

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 18 through 20 on the d20.

Expert Surgeon

Whenever you make a Wisdom (Medicine) check, you can choose to use your Rogue level in place of a d20 roll.

In addition, you gain access to surgical abilities that rival the most powerful arcane and divine magics. As an action, you can touch a creature and inflict the effects of either the contagion or regenerate spell, using your Intelligence as your
spellcasting ability. Once you recreate either spell you must finish a short or long rest before you can do so again.
