Heighten Turning

(Ghostwalk, page 35, DnD 3.0)

[General]

You can affect more powerful undead with your turning or rebuking attempts.

Prerequisite

Extra Turning, CHA 13

Benefit

When you turn or rebuke undead, you may choose a number no higher than your cleric level. Add that number to your turning check result and subtract it from your turning damage roll. If you're not a cleric, you may choose a number no higher than your effective cleric level (for instance, a paladin could choose a number up to two lower than her paladin level). If a prestige class increases your effective turning level, use your effective turning level.
