So I've look through a bunch of topic about the Swashbuckler's Precise Strike Deed. I get that with higher BAB scores this could add an additional +12 damage at level 6. However, I can't seem to find an answer for what happens when a player chooses to spend a Panache Point.
For simplicity, lets assume a level 6 Swashbuckler with no additional bonuses and a simple rapier. If both attacks hit and a Panache Point was spent, is the damage now 1d6+6, 1d6+12?
At level 11, is the damage 1d6+11, 1d6+22, 1d6+11 or is the damage 1d6+11, 1d6+11, 1d6+22 or is it the player's choice?
Lastly, is spending the Panache Point only usable when multiple attacks with the same weapon is possible such as with higher BAB scores or with a haste spell?
