The Bigger They Are [one-action] Feat 12Bravado Swashbuckler Source Player Core 2 pg. 168
With reckless speed, you dash, jump and swing around a creature to find a more vulnerable spot. Attempt to
Tumble Through a creature at least one size category larger than you, using the following effects.
Critical Success You move through the enemy's space, treating the squares in its space as
difficult terrain (every 5 feet costs 10 feet of movement). If you don't have enough Speed to move all the way through its space, you get the same effect as a failure. If you successfully pass through the target's square, the target gains weakness to your precision damage equal to half your level, which lasts until the end of your turn.
Success As success, but the weakness applies only against the next attack you make against the target.
Failure Your movement ends, and you trigger reactions as if you had moved out of the square you started in.
Critical Failure As failure, and you fall
prone.
Traits
Bravado: Actions with this trait can grant panache, depending on the result of the check involved. If you succeed at the check on a bravado action, you gain panache, and if you fail (but not critically fail) the check, you gain panache but only until the end of your next turn. These effects can be applied even if the action had no other effect due to a failure or a creature's immunity.
