Expert medicus

Through experience you have become an expert at non magical healing. 

1. You gain an added +2 to medicine checks to stabilize unconscious creatures. 

2. Since you have been using your medical kit often, you have learned to manage you inventory better. You gain an extra charge to your first aid kit. For every 5 character levels in your main class, you heal an extra 1d6 with the first aid kit (2d6 at level 5, 3d6 for level 10, etc.)

3. You can create a variety of potions of higher quality. To create a potion, you must either find the recipe for said ingredient or experiment . If you find the recipe, you must find every single ingredient in order to create said potion, any substitutes or omission of ingredients will count as experimentation. You must also spend 10 gold for the supplies and spend the concentration time required to create the spell. For experimentation: In order to experiment you must have one (1) rare ingredient. When created and consumed, you must make a constitution saving throw afterwards. The DC for experimentation is equal to the amount of ingredients times 2 plus 3.  So if you have 2 ingredients your DC would be 7, for 4 ingredients it would be 11, etc.

Thank you SachiQueen for making it far more understandable. You rock girl.
