Derring-do Feat 10
Source Pathfinder Advanced Player's Guide
When you compound Panache with even more derring-do, it somehow tends to work out.
When you already have panache, you can roll twice and use the higher result on checks to which the circumstance bonus for having panache applies (Tumble Through and any skill actions listed in your swashbuckler's style).
Traits
Anything that doesn't list another rarity trait (uncommon, rare, or unique) automatically has the common trait. This rarity indicates that an ability, item, or spell is available to all players who meet the prerequisites for it. A creature of this rarity is generally known and can be summoned with the appropriate summon spell.
FortuneA fortune effect beneficially alters how you roll your dice. You can never have more than one fortune effect alter a single roll. If multiple fortune effects would apply, you have to pick which to use. If a fortune effect and a misfortune effect would apply to the same roll, the two cancel each other out, and you roll normally.
SwashbucklerThis indicates abilities from the Swashbuckler class.
