Calling upon the dark power of the Plane of Negative Energy, you bolster the power of incorporeal undead.
The undead affected by this spell gain a +1 deflection bonus to Armor Class, +1d8 bonus hit points, a +1 enhancement bonus on attack rolls, and a +2 bonus to turn resistance. Each of these enhancements improves by the base amount for every five caster levels beyond 5th, so that a 20th-level caster grants undead +4 to AC, +4d8 bonus hit points, +4 on attack rolls, and +8 to turn resistance.
