Blessing of the Nine (3.5e Spell)

You temporarily transform the target of the spell into a creature of Baator, able to fight like the devil and move like a bat out of Hell. In addition to gaining a bonus to your base speed equal to 5 feet per 2 caster levels, you acquire a pair of wings that allow you to fly at your increased base speed (with good maneuverability), a +4 enhancement bonus to Strength as well as a pair of claws that deal damage based on your size (1d6 for a Medium creature). You also gain all the benefits of the outsider type (and the baatezu subtype) for the remainder of the spell's duration.

Devils are affected differently by this spell, gaining a +6 enhancement bonus to Strength instead of the normal +4 and the enhanced movement speed in addition to a one size category increase in the damage of all of their natural weapons.
