Bestow Greater Curse

You touch a creature, and that creature must succeed on a Wisdom saving throw at disadvantage or become cursed for the duration of the spell. When you cast this spell, choose the nature of the curse from the following options:

• The target becomes mortally fearful of anything that might harm it and automatically fails all ability checks or saving throws while aware of a danger near it.
• While cursed, the target must make a Wisdom saving throw each day at dawn, losing 1 Wisdom on a failed save. If the target has no Wisdom remaining after this, they fall unconscious and cannot be woken by anything but the wish spell.
• While cursed, the target must make a Wisdom saving throw at the start of each of its turns. If it fails, it wastes its action that turn shrieking and harming itself in whatever way possible, dealing the most damage possible.
• While the target is cursed, your attacks and spells deal an extra 8d8 necrotic damage to the target.

A remove curse spell suppresses this effect for 24 hours, after which the curse continues to function as normal. At the DM's option, you may choose an alternative curse effect, but it should be no more powerful than those described above. The DM has final say on such a curse's effect. The curses last for 1 year or until cured and can only be cured by greater restoration or similar magic.

At Higher Levels. Using a 9th level spell slot, the effect of the curse becomes permanent and can only be cured by the wish or magic of a similar caliber.
