Time Vortex

4th-level evocation (temporal)

Casting Time: 1 action
Range: 90 feet
Components: V, S, M (a clockwork butterfly)
Duration: Concentration, up to 1 minute

This spell destabilizes the flow of time in the target area, subjecting creatures caught in the vortex to temporal fluctuations that are visible as a spherical distortion with a 10-foot radius. Each creature within the sphere when you cast the spell must succeed on a Wisdom saving throw or be affected by the time vortex. While the spell lasts, a creature that enters the sphere or begins its turn inside the sphere must also make a Wisdom saving throw or be affected. Once a creature’s Wisdom saving throw succeeds, it is immune to this time vortex.

An affected creature can’t take reactions and must roll a d10 at the start of its turn to determine its behavior for that turn.

d10	Effect
1-2	The creature is affected as if by slow until the start of its next turn.
3-5	The creature is stunned until the start of its next turn.
6-8	The creature’s initiative result is reduced by 5. The creature begins using this new initiative result next round. Multiple occurrences of this effect for the same creature are cumulative.
9-10	The creature’s speed is halved until the start of its next turn.

You can move the temporal vortex 10 feet each round as a bonus action. An affected creature repeats the saving throw at the end of its turn, ending the effect on itself on a success.

At Higher Levels. When you cast this spell using a spell slot of 5th level or higher, the radius of the sphere increases by 5 feet for each slot level above 4th.
