It is my understanding that you can only select talents in the first row of a talent tree or a talent adjacent to a talent you already have. My question has to do with whether once you get to a talent tree level can you select any talent on that level.
For example (working from a document posted on the web), on the Bounty Hunter (Assassin) talent tree if you choose Grit and then Precise Aim, can you then choose Quick Strike or do you need to select Jump Up first. I assume the latter, but just wanted to make sure.
The latter is correct. Determining what talents you can select is described in the third paragraph of Aquiring Talents on page 65 of the Beta Text.
You can buy talents that that meet either of the criteria below:
Any talent on the top tier of an accessible talent tree.
Any talent links to another already puchased talent. ("links" are drawn through lines between the talents)
And then, of course, no talent can be purchased twice from the same position, e.g. a politico who has purchased "Kill with Kindess" in the top tier of their ree, can't buy KwK again for 5 points, but can buy it on the second tier of their tree if they meet the second criteria listed above. Similarly, that Politico could purchase Plausible deniablity twice for 5pts each because it appears twice on the top teir (each purchase meets the first criteria above). A third purchase of PD would cost 10 pts, because the third appearence of the PD in that tree is in the the second tier of that tree.
Hope that clears it up.
