Roiling Mudslide [two-actions] Feat 6Composite Earth Impulse Kineticist Primal Water Source Rage of Elements pg. 37 2.0
You form water and earth into a mudslide that smashes your opponents and coats them in mud. Each creature in a 30-foot cone takes 2d8 bludgeoning damage with a
basic Fortitude save against your class DC. A creature that fails is also
pushed 5 feet (or 10 feet on a critical failure) and coated in mud until the end of its next turn. While coated in mud, the creature falls
prone at the end of its movement any time it ends a
move action other than a Crawl or Step. The creature can attempt an
Acrobatics check or Reflex save against your class DC, avoiding the fall if it succeeds.
Level (+4) The damage increases by 1d8.
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 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.
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 connection to magical water.
Planes with this trait are mostly liquid. Visitors who can’t breathe water or reach an air pocket likely drown. The rules for aquatic combat (Player Core 437) usually apply, including the inability to cast fire spells or use actions with the fire trait. Creatures with a weakness to water take damage equal to double their weakness at the end of each round.
