Wave of Dread

Each creature of your choice in a 30-foot radius extending from you must succeed on a DC 5 Wisom saving throw, or die instantly of fright (creatures immune to fear, or otherwise not posessing a heart, therefore can't get a heart attack are immune), and if they saved against the immediate death, they must make a DC 15 Wisdom saving throw or become frightened of you for 1 minute. While it is frightened in this way, a creature must spend its turns trying to move as far away from you as it can, and it can't willingly move to a space within 30 feet of you. It also can't take reactions. For its action, it can use only the Dash action or try to escape from an effect that prevents it from moving. If it has nowhere it can move, the creature can use the Dodge action. At the end of each of its turns, a creature can repeat the saving throw, ending the effect on itself on a success.
