Vertigo Spasms

Vertigo Spasms simulates complete inner-ear or mental disruption. The target experiences severe probability manipulation — every coordinated action becomes unreliable. The character's inner-ear or spatial-perception circuit is overridden, throwing off all coordination rolls for the duration.

Built from a Sensory & Physiological Tag (vestibular disruption) combined with a Cognitive & Agency Tag (motor coordination interference) and a Probability Bias primitive that introduces Negative Bias (Disadvantage) on Physical Checks for the duration. Common in psychic and air-domain attacks.
