You can transfer the flow of time from one creature to another within range, speeding up one while slowing down the other. An unwilling creature must make a Wisdom saving throw when you cast the spell, ending the spell on a success. Otherwise it is affected by this spell for the duration, and can repeat the save at the end of each of its turns. Choose one of the following each for the affected creatures:
Speed Up. The creature increases its movement speed by 15 feet and gains an additional attack on each of its turns. That action can be used only to take the Attack (one weapon attack only), Dash, Disengage, Hide, or Use an Object action.
Slow Down. The creature decreases its movement speed by 15 feet, can only take one action or bonus action on each of its turns, and can't use reactions.
