VFX Effect

Design an effect the viewer can read in one frame and recognise every time.

What a good effect has

A shape grammar. Rings, shards, threads, arcs, columns. One family per source. The mage's effects are circles and constellation lines; the warrior's are straight edges and walls. Mixing grammars across one character reads as random.
A palette. Two colours and one accent. Stated in the design, repeated in every prompt.
A timing envelope. Wind-up (the tell), release, peak, decay — in seconds. A 0.3 s tell that the audience learns to read is what makes an ability fair in a game and legible in a film.
A cause. The effect follows a physical event: blade contact, palm strike, landing, the core reaching critical. Written cause-first in every prompt.
A scale rule. How big at rank 1, how big at ultimate. The ultimate is a different scale, not a different colour.
