Smite Evil

Paladin Supernatural Ability (1st Level)

Once per day, a paladin may attempt to smite evil with one normal melee attack. She adds her Charisma bonus (if any) to her attack roll and deals 1 extra point of damage per paladin level. For example, a 13th-level paladin armed with a longsword would deal 1d8+13 points of damage, plus any additional bonuses for high Strength or magical affects that would normally apply. If the paladin accidentally smites a creature that is not evil, the smite has no effect, but the ability is still used up for that day.
At 5th level, and at every five levels thereafter, the paladin may smite evil one additional time per day, as indicated on the table above, to a maximum of five times per day at 20th level.
