Jagged Berms [three-actions] Feat 6Composite Earth Impulse Kineticist Overflow Primal Wood Source Rage of Elements pg. 37
You conjure up to six cube-shaped mounds of packed earth. Each appears in an unoccupied square within 120 feet, fills its square, and provides cover. A mound has AC 10, Hardness 10, and 20 HP, and is immune to critical hits and precision damage. If destroyed, a mound becomes
difficult terrain. The mounds last for an unlimited duration, but if you use the impulse again, any previous one ends.
Sharpened wooden stakes protrude from each mound into adjacent squares. They can project from any of its sides; you choose which sides for each mound. For each square of wooden stakes a creature enters, that creature takes 2d6 piercing damage. Destroying a mound also destroys its stakes.
Level (+2) The HP of each section of the wall increases by 10, and the piercing damage increases by 1d6.
Traits
Composite: A composite impulse combines multiple elements. You can gain an impulse with the composite trait only if your kinetic elements include all the elements listed in the impulse's 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.
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.
Wood: Effects with the wood trait conjure or manipulate wood. Those that manipulate wood have no effect in an area without wood. Creatures with this trait consist primarily of wood or have a connection to magical wood.
These planes consist of trees and other flora latticed in organic patterns. Wood planes are often perfectly constructed to match their desired purpose or environment but aren’t usually outright hostile to visitors.
