Swashbuckler! is Going Back to the Drawing Board

So I ran a short playtest of Swashbuckler! with 6 players last night. Three were completely new to roleplaying games. Turns out that Swashbuckler! is incredible deadly and badass, making the tomb of honors look like child's play. I didn't throw anything to difficult at them (or what I at first perceived as too difficult at them), but there wasn't just a TPK, no. We went through 19 PCs that night. Nineteen fucking PCs. Regardless, Swashbuckler! is just a little too deadly at this time and I need at take most everything back to the drawing board.
