I want some chronomancy in DnD. Let’s make that happen!
Time Crawls
1st-level enchantment
Casting Time: 1 action
Range: 60 feet
Components: V, S, M (a sundial)
Duration: Concentration, up to 1 minute
Choose up to three creatures that you can see within range. Those creatures lose their ability to move on their turn unless they spends an action. At the end of each of a target’s turn, the target can attempt a Wisdom saving throw to regain the ability to move without spending an action. On a success, the spell ends on the target.
At Higher Levels: When you cast this spell using a spell slot of 1st level or higher, you can target one additional creature for each slot level above 2nd.
