Sacred Strike

(Book of Exalted Deeds, page 45, DnD 3.5)

[Exalted]

Your sneak attack is enhanced by your unshakable faith in a good-aligned deity.

Prerequisite

Sneak attack class ability

Benefit

When you use your sneak attack ability against an evil creature, roll d8s for your sneak attack dice (instead of d6s) and your sneak attack damage is considered good-aligned for purposes of overcoming damage reduction.
