This spell is a part of the Time Ripple spell chain and is found in the Time Ripple rune stone.
Time is not as stable as most people assume. It flows, yes - steadily, reliably, one moment into the next - but it flows because it is moving, and anything that moves can be disturbed. The posteramancer learns this early. One of the first things Fate shows them is that the current of time, for all its constancy, has a surface. And that surface can be broken.
Time Ripple is exactly what its name describes. The posteramancer pushes outward through their runic soul, sending a wave of disrupted temporal energy radiating in all directions. The ripple is not targeted. It is not precise. It does not distinguish between friend and foe - it simply spreads, the way all ripples do, touching everything it reaches equally. Those caught in it feel it as a sudden wrongness in their body, a dissonance between where they are and where time thinks they should be. Movement becomes difficult. The body resists. For three rounds, everything in the area moves as though pushing against a current it cannot see. The posteramancer will eventually learn to do far more with time than disturb its surface. But this is where it begins, with the simple, foundational discovery that time can be touched. That it responds. That it ripples.
