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.

Resourceful

Beginning at 15th level, you're always ready to support those who travel with you. If you begin combat with no lesser potions prepared, you can scrounge around in your supplies, and prepare one lesser potion of your choice.
Additionally, once per day after finishing a short rest, you can regain one spell scroll that you prepared at the end of your previous long rest.
