How it's made

Source
a charge of magical energy that fails to ignite. Three parts: a pitched energy tone that sags downward, a few weak sputters as the charge stutters, and a smoky hiss of leaking gas-like noise.
Body
the tone is a triangle plus a quiet sine an octave below, gliding from ~900 Hz to ~250 Hz with a slow wobble that widens as it dies; each sputter is a 20-60 ms pitched blip (also falling) with a noisy crackle on top, band-passed around 1.5-4 kHz. The hiss is pink noise through a band-pass that sweeps from ~3.5 kHz down to ~900 Hz, so it darkens like smoke settling.
Envelope
sputters start close together and spread out (gaps grow ~1.5x) while their level falls; the tone fades over ~0.7 s; the hiss swells for ~0.1 s and trails off past 0.8 s.
Variation
`rng` jitters sputter timing, strength, blip pitch, pan and the wobble phase; macros set how many sputters there are, how far the pitch falls and how smoky the hiss is.
