VFX prompts need material behavior, source, timing, and consequence. Treat every effect as physical: it starts somewhere, interacts with light and objects, changes over time, and ends in a visible state. Avoid generic words such as magical, explosive, or cinematic unless they are translated into particles, fluids, smoke, light, debris, deformation, or energy behavior.

Intent

The user wants wonder, and wonder dies the moment it stops obeying physics. This skill's purpose is magic with a budget of cause and effect: every effect has a source, a journey, and an ending, so the impossible reads as witnessed rather than rendered.

Effects Contract

State: effect source, material, motion path, interaction with light, interaction with objects, dissipation, and endpoint.

Effect	Prompt-ready phrase	Stability note
Product particles	gold dust particles spiral from behind the logo, catch the backlight, then settle on the table	Keep logo and bottle rigid.
Energy	thin blue electrical arcs crawl along the cable, briefly illuminating fingerprints on the plug	Keep arcs attached to source.
Smoke	cold white vapor rolls over the rim, sinks down the glass, and thins near the tabletop	Describe density and direction.
Transformation	paper edge chars inward from the corner, flakes curl and fall, final logo remains untouched	Protect identity anchor.
Weather	wind pushes rain diagonally across the frame, puddles ripple outward from each step	Tie weather to surfaces.

VFX Integration Rules

Use one hero effect per clip. Anchor the source to a clear object or body part. Make the effect respect gravity, wind, collision, reflection, and occlusion. For VFX near faces, hands, logos, or text, keep the core identity stable and place the effect around it rather than through it.

Timing and Dissipation

Effects need an endpoint: settle, fade, evaporate, freeze, collapse, glow out, or leave residue. If the effect is complex, use a three-step timing phrase: forms -> travels -> dissipates. Avoid perpetual effects with no consequence because they often become noisy overlays.
