Nightmare (Illusion)
Level: Mage 5, Night 3, Fate 5, Bard 5, Alienist 5, Blackguard 5, Twilight Huntsman 5
Mana: 45. Base Success: 60%.
Casting this spell sends a horrific nightmare to all the sleeping creatures on the current level within [caster level x 50] feet, even outside your sight. The creatures suffer 2d6 points of fatigue loss, 1d8 damage to Wisdom and Charisma and 1d6 points of psychic damage per odd caster level.
(Remember that spells have verbal components, and casting near sleeping creatures will awaken them before they can be affected -- but Nightmare has a greater range than the 120 feet away from which spellcasting can be heard.)
