Barrier of Boreal Frost [three-actions] Feat 14Cold Impulse Kineticist Manipulate Overflow Primal Water Source Rage of Elements pg. 33
You form an intricate structure of ice, such as a wall of bricks made of packed snow or a screen of enormous icicles. This has the effect of a
wall of ice spell with a spell rank equal to half your level rounded up. It can only be a wall (not a hemisphere), and you choose whether the ice is transparent or opaque. The wall lasts until the end of your next turn, but you can Sustain it up to 1 minute.
Traits
Cold: Effects with this trait deal cold damage. Creatures with this trait have a connection to magical cold.
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.
Manipulate: You must physically manipulate an item or make gestures to use an action with this trait. Creatures without a suitable appendage can’t perform actions with this trait. Manipulate actions often trigger reactions.
Overflow: Powerful impulses temporarily overdraw the energy of your kinetic gate. When you use an impulse that has the overflow trait, your kinetic aura deactivates until you revitalize it (typically with Channel Elements). Extinguishing your element this severely is taxing, and consequently, you can use only one overflow impulse per round, even if you reactivate your kinetic gate.
Primal: This magic comes from the primal tradition, connecting to the natural world and instinct. Anything with this trait is magical.
Water: Effects with the water trait either manipulate or conjure water. Those that manipulate water have no effect in an area without water. Creatures with this trait consist primarily of water or have a magical connection to the element. Planes with this trait are mostly liquid, perhaps with pockets of breathable air.
