Great Smiting
( Dungeon Master's Guide v.3.5, p. 209)[Epic]
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.)
