Tides of Time

Waves of temporal energy erupt from a location within range, slowing creatures more the further they've fallen into it. 

Any creature in the area must make an Intelligence saving throw. On a failed save, a creature is affected by the tides depending on how close they are to the center of the spell radius (see below).

At the end of each turn, a creature can make an Intelligence saving throw to be unaffected by the spell. On a save, the creature cannot be affected by the spell for the next 24 hours. 

Area of Effect: 

• 30 ft: Speed is reduced 25% and the creature may take an action or bonus action, but not both. 
• 15 ft: Speed is reduced by 50% and the creature may take an action or bonus action, but not both. They also have disadvantage on Dexterity saving throws and can not take reactions. 
• 5 ft: Speed is reduced by 75% and has disadvantage on Dexterity saving throws. They cannot take actions or reactions, only bonus actions.
