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 connection to magical earth.
These planes are mostly solid. Travelers arriving upon an earth plane risk suffocation if they don’t reach a cavern or some other air pocket within the plane’s solid matter. Creatures who can’t burrow are entombed in the plane’s substance and must attempt to dig their way toward an air pocket. Air creatures are ill at ease, as they rarely have the space to move freely through even the loftiest warrens.
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.
A creature with this trait is primarily constituted of or has a strong connection to primal magic.
