Sleepless Curse

When this dire enchantment is cast, the wizard curses a single creature to endure restless and sleepless nights. For the duration of the spell, the subject cannot sleep. Furthermore, the creature is immune to all spells that cause sleep, and not even a dispel magic can relieve this condition. However, a remove curse by a caster of level equal to or higher than the wizard lifts the enchantment, as does any wish spell. The wizard can cancel the spell at any time.

For each sleepless night, the creature loses one hit point, as well as one point from each ability score (if not rated, roll 3d6 for the creature). When any score reaches zero, the creature dies of exhaustion and delirium. Once the spell ends, the creature recovers ability score points and hit points at the rate of 1 hit point per hour for each hour of sleep after the first eight. Note that this spell also affects creatures that do not actually sleep, but have extended periods of reduced activity.

The material components for this spell are a dried petal of a blue lotus flower and a small, burning brazier, into which the petal is dropped.
