Not to mention that it is insanely superior to "Skirmisher" {7% Dodge while swashbuckling with a Buckler in your off-hand}! Unless that is...That's +7% MAX Dodge!
Why do I feel that this tree is aimed at making people NOT use Bucklers?
Oh and for the record - I was afraid of one thing when I first heard about this tree and it seems to have come to pass:
Why is this a Bard ONLY Tree?
Why can't Fighters, Rangers and Rogues swashbuckle without taking Bard Levels? Seemingly a heck of a lot of Bard levels too!
P.S. Will Repeater X-Bows be usable with this tree?
Because if not I cannot see anyone taking the Rune-Arm bonuses!
