Command Elemental [two-actions] Feat 4Impulse Kineticist Primal Source Rage of Elements pg. 21
You grasp the animating force within an elemental creature and bend it to your will. Choose a trait matching one of your kinetic elements and target an
elemental creature within 30 feet that has the chosen trait. The elemental becomes
controlled by you if its level is equal to or lower than your level — 3, or
slowed 1 for as long as you Sustain the effect if its level is equal to your level — 2 or higher. It can attempt a Will saving throw against your class DC to resist being controlled by you or to end the slowed effect. If the target is already under someone else's command, it can't be slowed by this ability, and the controlling creature also rolls a saving throw, with the elemental using the better result.
Critical Success The target is unaffected and is temporarily immune for 24 hours.
Success The target is unaffected.
Failure The elemental creature is controlled or slowed as long as you Sustain the impulse, up to 1 minute. This effect ends if you or an ally attacks the elemental.
Critical Failure As failure, but you can Sustain the impulse up to 1 hour.
Traits
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.
