Temporal Stasis
Temporal stasis is a commonly used chronomancy spell. Casting the spell on an object or being will suspend it in time. While this spell is active, their flow of time ceases, as do bodily functions, consciousness, and ageing.
The spell must be cast again for the object or being to be released. The opposite of Temporal Stasis is Temporal Flux.
