The caster furiously swipes the air in front of him tearing reality apart in the form of a window to the far realm making anyone in front of him to catch a glimpse of the horrors of that maddening dimension. Anyone in a 30 feet cone in front of the caster must make a Wisdom saving throw. On a failed save the victim takes 5d6 psychic damage and must roll once in the Short-Term Madness table (D.M.G. pag:259), on a successful save the victim fools himself to believe that what he saw was merely an illusion taking half damage and avoiding falling into madness. At the end of each turn, a character affected by a Short-Term Madness effect can repeat the saving throw to recover from the effect.

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. When you cast this spell using a spell slot of 6th level or higher, roll once in the Long-Term Madness table in addition to the roll in the Short-Term Madness table. When you cast this spell using a spell slot of 8th level or higher, make one roll in the Indefinite Madness table, one additional roll in the Long-Term Madness table and one additional roll in the Short-Term Madness table (each of the short term madness effects requires a different save to prevent or get rid off).
