Temporal Winch (Chronomancy School of Magic)

The timestream around you is restricted or expanded, affecting nearby creatures’ perception of time. You create a 30-foot sphere centered on yourself, within which time appears to either slow or accelerate.

If you choose to slow the manifestation of time, all creatures within the sphere can take an additional action or bonus action on their turn while the spell lasts. If instead you choose to accelerate it, the affected creatures can only take one bonus action and move a distance of half their speed (in whatever order they choose), after which their turn ends.
