So I recently made an amusing discovery. Daring Outlaw is often regarded as the saving grace (rimshot) of the Swashbuckler class, and it has the Grace class feature (+2) as a requirement, meaning you can’t trade Grace away for any ACFs. But, the Duelist prestige class also gives you Grace +2 at level 4, letting you get around that!
However, Duelist is, to put it kindly, not fantastic, and four levels in it is a big investment for this exploit. Are there any classes (base or prestige) other than Swashbuckler and Duelist that give you Grace as a class feature?
