Remove cooldowns for first aid and doctor skill, and make players able to use theyr skills only if they have first aid kit (or doctors back, for doctor skill) equiped. To make it easier to find simple first aid kit and doctor's bag, add the possibility of buying it through a dialogue with doctors in all cities, and reduce the price to 300 caps. After several uses (maybe eight) of first aid kit (doctor's bag) it disappears. And finaly, review existant boosts for FA kits, and doctor's bags.
I mean:
First aid kit - gives possibility to use first aid skill,
First aid MK2 - gives possibility to use doctor skill + 50% boost to skill,
Doctor's bag - gives possibility to use doctor skill,
Docto's bag MK2 - Gives possibility to use doctor skill + 50% boost to skill.
Something like this.
