You unleash a shimmering lance of psychic power from your forehead at a creature that you can see within range. Alternatively, you can utter a creature's name. If the named target is within range, it becomes the spell's target even if you can't see it (but it is still unaffected if it is behind Total Cover). If the named target isn't within range, the lance dissipates without effect.

The target must make an Intelligence saving throw, taking 7d6 Psychic damage and potentially becoming

Incapacitated

Critical Success (+10). The target is unaffected.
Success. The target takes half damage.
Failure. The target takes full damage and is Incapacitated until the start of your next turn.
Critical Failure (–10). As failure, except the target takes 1.5× damage and you reach into its mind; you know its exact location for the next minute.

At Higher Levels: When you cast this spell using a spell slot of 5th level or higher, the damage increases by 1d6 for each slot level above 4th.
