Palette
pure color - in-game = the 32-slot variant swap, crossplay-safe
Surface FX
animated on-sprite shaders - local overlay
Around FX
auras around the mon - glow, flames, orbits, backdrops (some partial)
Exotic (multi-sprite)
layered copies of the full look around the mon - depth orbits, time echoes, companions
Form
the body itself transforms - fake 3D, materials, lineage recolors (one at a time, stacks with everything else)
Moments
finite event sequences that loop automatically - watch a few seconds
