Control Elements

You can mold fire, wind, water, life, and earth. This spell can control all nature, and can be used offensively or in other more creative ways. You may mold naturally occurring aspects of the element of your choosing, allowing you to reshape or move no more than 1 square foot of plant, stone, soil, and ice, water, fire, air, or allowing you to deal 1d4 damage of your chosen element type (lightning, fire, cold, necrotic, acid).

This damage increases by 1d4 at level 5 (2d4), level 11 (3d4), and level 17 (4d4)
