prone when you reach the surface, and are

Traits
Earth: Effects with the earth trait either manipulate or conjure earth. Those that manipulate earth have no effect in an area without earth. Creatures with this trait consist primarily of earth or have a magical connection to that element. Planes with this trait are mostly solid, with caverns and other hollow pockets.
Impulse: The primary magical actions kineticists use are called impulses. You can use an impulse only if your kinetic aura is active and channeling that element, and only if you have a hand free to shape the elemental flow. The impulse trait means the action has the concentrate trait unless another ability changes this. If an impulse allows you to choose an element, you can choose any element you're channeling, and the impulse gains that element's trait.
Primal: This magic comes from the primal tradition, connecting to the natural world and instinct. Anything with this trait is magical.
