Starting at 1st level, Your eyes are the gateway to your new gifts. They shine with a foreign power. You can shoot rays of magic as a bonus action at random to enemies in your sight. Roll a d4 to determine the effect of your beam. You may only use this feature as many times as your proficiency level per long rest.

2 Slowing Ray: The target must succeed on a Constitution saving throw. On a failed save, the target's speed is halved for 1 minute, and it can take either an action or a bonus action on its turn, not both. The creature can repeat the saving throw at the end of each of its turns, ending the effect on a success.
3 Fear Ray: The target must succeed on a Wisdom saving throw or be frightened for 1 minute. The target can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success.
4 Telekinetic Ray: The target must succeed on a Strength saving throw or the sorcerer moves it up to 30 feet in any direction. It is restrained by the ray's telekinetic grip until the start of your next turn or if you can no longer see the creature.
