Prerequisite: fighter or barbarian with a constitution score of at least 14
Time and time again by carefully observing and practicing the movements of the many druids, sorcerers, warlocks and wizards you have fought with and against, by sheer force of will, you have stumbled upon the somatics that grant you access to the basic building blocks of minor elemental power. Using the correct somatic, you gain the spellcasting ability that allows you to cast each of the following spells once per short rest: control flames, mold earth, shape water, and thunderclap. You regain the ability to cast these spells when you finish a short rest.
Constitution is your spellcasting ability for these spells.
