Physician

Not every artificer dreams of creating cannons and mechanical soldiers. Some devote their intellect to understanding the body instead of destroying it.

Physicians combine alchemical science, anatomical expertise, and ingenious medical devices to perform miracles some mistake for magic. Their tools include surgical kits, stimulant injectors, trauma foam, regenerative compounds, and lifesaving field equipment.

On dangerous expeditions, a Physician is often the most valuable member of the crew. While others fight monsters and enemies, the Physician fights against the Grim Reaper.  

Level 3: Medical Officer

Beginning at the 3rd level, your studies have focused on preserving life through anatomy, chemistry, and emergency medicine rather than the construction of weapons.

You also gain proficiency with the Herbalism Kit fi you do not already possess it.

Whenever you cast an artificer spell that restores hit points, the target regains additional hit points equal to your intelligence modifier (minimum of 1)

Level 9: ICU

Beginning at 9th level, you have mastered emergency trauma care. 

When a creature you can see within 30 feet would be reduced to 0 HP, you can use your reaction to cause it to drop to 1 HP instead.
