You combine grace and stealth to deadly effect.
Prerequisite: Grace +1, sneak attack +2d6.
Benefit: Your rogue and swashbuckler levels stack for the purpose of determining your competence bonus on Reflex saves from the grace class feature and the swashbuckler's dodge bonus to AC. For example, a 7th-level rogue/4th-level swashbuckler has grace +2 and gains a +2 dodge bonus to AC, as if she were an 11th-level swashbuckler.
Your rogue and swashbuckler levels also stack for the purpose of determining your sneak attack bonus damage. For example, a 7th-level rogue/4th-level swashbuckler would deal an extra 6d6 points of damage with her sneak attack, as if she were an 11th-level rogue.
