A 292

This is largely a feature of various spells in Book of Vile Darkness, a 3.0 D&D supplement. See SOULS AS POWER on page 33. Do note that this non-updated 3.0 source is subject to the usual rules. From Dungeon Master's Guide on page 4:
This is an upgrade of the d20 System, not a new edition of the game. This revision is compatible with all existing products, and those products can be used with the revision with only minor adjustments.
Your individual DM will decide what adjustments to make before material existing before D&D 3.5 may be used. For instance, the DM could decide to do away with these spells as the simplest adjustment.
