The caster furiously swipes the air in front of him riping reality in the form of a window to the beyond making anyone in 20 feet cone in front of him to catch a glimpse of the horrors of that maddening dimension.
Anyone in the range of the spell must make a CHA saving throw versus the spell save DC of the caster, on a successful save the victim fools himself to believe that what he saw was merely an illusion and is not affected by the spell, on a failed save the victim takes 5d6 psychic damage and must roll once in the Short-Term Madness table.
If you cast this spell with a spell slot higher than 4 increase the damage by 1d6 for every level above 4, additionally give a -1 to the saving throw of the victim per spell slot level used above level 4.
If you cast this spell with a level 6 spell slot or higher roll in the Long-Term Madness instead.
If you cast this spell with a level 9 spell slot roll in the Indefinite Madness table and make the CHA saving throw fail instantly.
