Great Smiting

Type: Epic
Sources: Dungeon Master's Guide v.3.5
Epic Level Handbook

Your smite attacks are much more powerful than normal.
Prerequisite: Cha 25, smite ability (from class feature or domain granted power)
Benefit: Whenever you make a successful smite attack, add twice the appropriate level to damage (rather than just your level).
Special: You may select this feat multiple times. Its effects stack. Remember that two doublings equals a tripling, and so forth.
