Frightening Gaze

Frightening Gaze (Costs a bonus action)
The lich fixes its gaze on one creature it can see within 10 feet of it. The target must succeed on a CON CHECK[DC 10] against this magic or become frightened for 10 turns.
The frightened target can repeat the saving throw at the end of each of its turns, ending the effect on itself on a success. If a target’s saving throw is successful or the effect ends for it, the target is immune to the lich’s gaze for the next 6 hours. You must be atleast level 10 to become immune to 6 hours.
