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.

Improved Potions

At 10th level, you've greatly improved the process of supplying an adventuring party. You now prepare the improved version of each of your lesser potions at the end of every long rest.
Your improvements to your potions have made them much smaller, without losing any of their potency. Potions you have made yourself (lesser and regular) can now be consumed as a bonus action by friendly creatures.
