Field Medic

As a field medic, it's your duty to run head first into battle to support your teammates using your medical expertise. 

Medical Training

When you choose this archetype at 3rd level, you gain proficiency with the herbalism kit and medicine. You can craft 1 potion during a long rest.

Additionally, you can use a health potion on yourself or an ally using your cunning action.

Knowledge of anatomy

Starting at 3rd level, your sneak attack bonus damage reduces the targets max health by half the bonus damage dealt.

Nobody left behind

Starting at 9th level, your movement speed is increased by 15feet when moving towards a downed ally. This applies to all forms of movement possessed by the user such as swim speed and flight speed.

You can grapple teammates with no grapple checks to move them from danger. Normal restrictions to movement speed still applies when moving an teammate. If they suffer from a condition that means they no longer ally with you it does not apply.

Mastery of Medcine

Beginning at 13th level, when you use a healing potion on a teammate re roll any dice roll of 1 (the second roll must be kept). When using a healing potion on a downed enemy it heals for the maximum amount. 

Revenge for the fallen

Starting at 17th level, when a teammate is downed, sneak attacks have no requirements for activation against the enemy that downed the teammate. Once the enemy is downed, the effect transfers to the next nearest enemy in sight. This effect ends once all the enemies that are present when the teammate was downed are defeated, when there is no enemy in sight, or 10mins.
