Gaze of the Far Realm (5e Class Feature)
From D&D Wiki
Gaze of the Far Realm
Warlock of the Great Old One, replaces the Create Thrall feature.
You have learned how to make others see what your patron is. Starting at 14th level, as an action, you can force other creatures within a 30 ft cone originating from you to make an Intelligence saving throw. On a failure, they take 5d8 psychic damage and are inflicted with short-term madness. You may use this feature again after finishing a long rest. On a success, the creature takes half damage and isn't inflicted with short-term madness.
