Supply Specialist

Source: Children of the Dragon

The Supply Specialist is a fighter who focuses less on their own martial prowess, and more on how they can enable the other members of their adventuring party to rise to their fullest potential. Through the use of potions and magical scrolls, they ensure that their allies are always prepared to face whatever challenge they come across. This subclass is popular among kobolds due to their affinity for teamwork, as well as their desire to aid their "dragon" allies to the best of their abilities.

Potion Master

When you select this martial archetype at 3rd level, you can create a number of lesser potions equal to your proficiency bonus at the end of every long rest. You can select any of the potions from the Lesser Potions list, as long as you meet the level prerequisite. Additional types of lesser potions become available at 7th, 10th, and 15th level. The lesser potions described in this subclass are temporary potions, and function differently from regular potions. Creatures can only be under the effect of one lesser potion at a time. Consuming a lesser potion with a duration longer than instantaneous immediately ends any current lesser potion effect (except for the Quartermaster feature's lesser potion effect). These lesser potions lose their potency after 24 hours.
Lesser potions can be distributed to the party at any point during the adventuring day, and can be consumed as an action. You can use your action to drink a potion yourself, or administer it to a friendly creature within 5 feet of you.
If the lesser potion has a choice of effects, then you must choose which effect upon creation. However, you can quickly change that choice as an object interaction on your turn by adding minor ingredients, before it is consumed.
You gain proficiency with the Herbalism Kit, which allows you to create potions of healing with the rules in Xanathar's guide to everything (page 130). In addition, you count as one size category larger when determining your carrying capacity.
