Paladins have received a few boosts to their damage output against their traditional foes through the Hunter of the Dead and Knight of the Chalice prestige enhancement lines, and their first capstone continues to emphasize the good fight against darkness.
Paladin Weapons of Good
Prereq: Level 20 Paladin
Cost: 2 AP
Benefit: Any weapon you wield is considered Good aligned for purposes of bypassing damage reduction, deal 1d6 additional holy damage against all evil opponents and an additional 2d6 light damage against evil undead or evil outsiders.
This enhancement brings an extra bit of punch to a Paladin, especially when they're fighting evil outsiders. The extra dice of damage from Weapons of Good stack with other weapon enchantments, so even your common Holy Sword can become a dangerous weapon unless you're running through a quest like Purge the Heretics.
