Azareck's Unrelenting Madness

You harness the power of the madness of the Far Realm - ravaging the mind of your target with malign insights.

Choose 1 target within range - the target must make a Wisdom saving throw. On a fail, the target takes 8d10 Psychic damage and suffers a trait of Short Term Madness, on a success they take half damage and don't go mad. During the duration that they have Short Term Madness they have disadvantage on ability checks and saving throws that involve their mental statistics.

At Higher Levels: When you cast this spell using a spell slot of 8th level or higher, the damage increases by 2d10 for every level above 7th. Furthermore, when cast at 8th level the target gains a trait of Long Term Madness in addition to Short Term Madness. When cast at 9th level the target gains a trait of Indefinite Madness in addition to Long Term and Short Term Madness.
