So I've just run the adventure yesterday with a party of three players, one of them being a Makashi Duelist. The game went okay and players wanted to turn our one-shot into a small campaign. At the end, they gave me their sheets so I could type in some info and plan for the next game.
That was when I noticed that the Makashi Duelist Tree allows you to buy Improved Parry without having the Parry Talent (from the Feint Talent). Okay, that would be fine if only the Improved Parry Talent would give us a brief description of the actual Parry mechanics.
Considering that not all of us are going to have Talent Trees and that having to look up a Talent that you do not possess gives players some extra work, I'd suggest including Parry's description in Improved Parry or removing the direct link, only allowing a character who actually has Parry to purchase its Improved Form.
