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.

Effects with the metal trait conjure or manipulate metal. Those that manipulate metal have no effect in an area without metal. Creatures with this trait consist primarily of metal or have a connection to magical metal.

These planes consist of chaotic and shifting structures and oceans of metal. Metal planes tend to exist in a state of change and decay, leaving plentiful pockets of air for visitors to breathe or move within. Creatures unlucky enough to be entombed in the plane’s substance risk suffocation if they can’t phase through metal. Wood creatures find the lack of stability and soil on a metal plane disconcerting and often fail to thrive in such environments.

This magic comes from the primal tradition, connecting to the natural world and instinct. Anything with this trait is magical.

A stance is a general combat strategy that you enter by using an action with the stance trait, and that you remain in for some time. A stance lasts until you get knocked out, until its requirements (if any) are violated, until the encounter ends, or until you enter a new stance, whichever comes first. After you use an action with the stance trait, you can’t use another one for 1 round. You can enter or be in a stance only in encounter mode.
