Shard Strike [two-actions] Feat 1Impulse Kineticist Metal Primal Source Rage of Elements pg. 30
Jagged metal shards form in the air and lash out from you. You choose shards or spines, which changes the area, damage type, and critical failure effect. Each creature in the area attempts a basic Reflex save against your class DC. Shards deal 1d6 slashing damage in a 15-foot cone, and a creature that critically fails takes 1d6
persistent bleed damage. Spines deal 1d6 piercing damage in a 30-foot line, and a creature that critically fails is
clumsy 1 until the start of your next turn.
Level (+2) The damage increases by 1d6.
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.
Metal: 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.
Primal: This magic comes from the primal tradition, connecting to the natural world and instinct. Anything with this trait is magical.
