I need clarification regarding a human Bladebound Kensai Magus in PFS.
Kensai - "A kensai is proficient in simple weapons and in a single martial or exotic melee weapon of his choice."
Bladebound - "A black blade is always a one-handed slashing weapon, a rapier, or a sword cane."
a) Does the PC get the Aldori Dueling Sword exotic weapon proficiency for free at 1st level? Or would the player be required to spend a feat to get the weapon proficiency?
b) Does the PC only get the Black Blade benefits when using the Aldori Dueling sword 1-handed?
Thanks in advance for your help.
